Technical Overview
I. Important Notes
For correct operation of this appliance, it is essential to observe the manufacturer’s instructions.
If this system is to be installed permanently as a POU or POE system,
installation must be carried out by a qualified plumber or authorised
technician to comply with Australian Plumbing Codes. This system contains
electrical components and plumbing components; Use caution and if
leaking occurs, turn the power off immediately before conducting
maintenance or repair to the system.
This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the
appliance.
If the supply cord is damaged, it must be replaced by a special cord or
assembly available from the manufacturer or its service agent.
II. Before You Purchase/Open
The system requires specific working conditions to be met before installation, some general guidelines* are
listed below. If these conditions are not met, the system may not be suitable for the application and may not
function as specified.
These systems are designed for filtration on mains water for the removal of minerals, salts and other
impurities. The system may also be used on other sources such as Bore Water however you should
enquire with the supplier before purchasing for any use other than mains water to ensure the system is
correct you the application.
III. Space Requirements
The LSRO Systems are not IP rated and therefore are not suitable for external installation without adequate
weatherproofing or cover from the elements including but not limited to Rain/Moisture & Frost.
The Frame of the system includes mounting holes so the system can be mounded to a wall. It is
recommended that the system be mounted if possible, rather than free-standing as this will help support the
weight of the system when full of water. If necessary, the system is able to also free stand.

If the system is to be enclosed in a cover, allow adequate ventilation around the pumps & power supplies to
prevent overheating.
IV. Before You Begin Installation
These RO units come pre-assembled on the bracket will all connections in place. These units are tested for
leaking before they are sent to ensure there are no leaks due to assembly. Due to transit, fittings and other
components may become loosened or damaged. Ensure the system is inspected for damages prior to
employing a plumber for installation.
V. What is Reverse Osmosis
The Reverse Osmosis Membrane is the workhorse of any RO system. It is constructed from a wrapped
semi-permeable membrane material that uses pressure to separate impurities such as ions, minerals and
other larger molecules from the water, carrying them to waste.
*Reverse Osmosis membranes do not have a L Capacity for filter replacements due to the variables that
can make the filter life vary significantly. This is mostly due to the water quality. The most accurate way to
test an RO membrane for effectiveness is to use a TDS Meter. TDS meters measure the total dissolved
solids in ppm in the water. To test your membrane, get a baseline reading out of your tap (unfiltered water)
and then compare that to a reading directly off the membrane (disconnect the tube before it goes into the
post filter cartridge). You can expect to get a difference of approx. 90-98% between the readings which
indicate that the membrane is functioning correctly. If this % is beginning to drop below 90% it suggests
that the RO membrane requires replacement.
VI. Example Applications
The LSRO systems are versatile and are suitable for a range of different uses. There are 3 main
applications for these systems; Manufacturing Water, Bore Water TDS Reduction & Medical
Sterilisation
Manufacturing Water generally required town water to be filtered through the RO membranes to reduce or
remove the dissolved solids from the water. These systems are favoured to produce this water ‘in house’
rather than purchasing commercial quantities of de-mineralised or distilled water which can be costly. Most
mains water applications are straight forward however some water supplies contain higher levels of
hardness which may require treating before the system.
Bore Water filtration is used when the water meets specific conditions where an RO unit will be suitable to
remove elevated salt levels in the water (generally TDS <2,000 mg/L*). Where salt levels exceed the
ADWG and need to be removed to supply potable water to a household.
Medical Sterilisation; it is now a requirement for dental & medical industries to utilise reverse osmosis +
de-ionised + UV sanitised water for use in equipment sterilisation. These systems can feed 0 TDS water
into Autoclave systems for the compliant sterilisation of medical equipment. (UV system not included).
VII. Installation with other Systems
It is common for these systems to be supplied with other additional filtration systems for different
applications. The most common of these would be a Water Softener. Below are some example scenarios.
NOTE: These are just guidelines and may be different depending on the requirements of the job. Check
with the client or supplier as to which type of installation order is required for not standard installations.
UV Systems: There are 2 ways to utilise UV with an RO system
1. UV can be used to sanitise the incoming feed water into an RO system. This is generally required on
scenarios where there are high or potential bacterial loading levels in the feed water. Bacteria can severely
affect an RO system performance and may cause Bio-Fouling. UV is used to eliminate or significantly
reduce bacteria.

2. Post storage sanitation is required if your RO water is filtering into a storage tank. This is the same
principle as treating rain water from a tank into your house. While RO water is generally free from
contamination, it is possible for the stored water to become contaminated especially if the tank is not sealed
or mixed with rain water.
Water Softener: Water softening is generally used when the feed water hardness, iron or manganese
exceeds the feed water requirements for the RO system (outlined in Technical Overview Sec. II.). A
Reverse Osmosis System is much more efficient at removing salts such as sodium chloride, rather than
hardness (calcium carbonate). Hardness produces scale and this scale can block a membrane or increase
the rate at which the membranes need to be chemically treated with an acid for de-scaling. It is better to
have higher incoming salt rather than higher hardness. For this reason, a water softener is installed behind
an RO System.
Due to the flow rates of a water softener, it will generally need to be installed in the following order: Feed
Supply Softener Holding Tank Pump RO System Use or further filtration.
Aeration/Filtration: Given the correct water chemistry, levels or iron/manganese may be the only issue in
the water. This method is designed to remove these metals from the water without affecting the other
minerals in the water and without increasing the salt levels. The aeration/filtration will be set up in the same
configuration as the water softener.
Calcite Filter: Reverse Osmosis will strip the minerals and salts from the water. The trade off is that the
water will then usually become ‘aggressive’ much like rain water. The pH will be low and the LSI of the
water will be low.
To use this water safely in a domestic setting, the pH and LSI will need to be balanced by using a Calcite
Filter. This will dissolve small amounts of calcium into the water to balance the pH and LSI. The most
common use of a calcite filter is in the following orientation: RO System Tank Calcite Filter 
Standard Filtration (Big Blue) UV House
De-Ionising (Demineralising): DI units are common as they are now required for medical sterilisation. DI
systems or housings are installed in the following configuration; RO System Tank (If Applicable) DI
Filter Direct Point of use.
Installation Introduction
I. Site Preparation
When a suitable installation location is identified, you will need to determine if the system will be mounted
to a wall or free-standing. The System should ideally have both the water supply (feed water) &
Storage/Point of use within a 5m radius of the system to reduce negative effects on the pressure/flow and
performance of the system. It is also recommended that the process water (filtered water) does not have to
travel more than 2m elevation above the system. This will ensure that minimal backpressure is applied to
the pumps. Where possible, have the water running to a point lower than or at the level of the system for
best results.
Ensure that adequate space is allowed for to access all parts of the system and if mounted to a wall, the
fixings should be removable which can help maintenance.
II. Installation – Mounting
When mounting the system, you will need to position the system to the desired location and mark out the
mounting holes. NOTE: it can help to unscrew and remove the blue cannisters on the front of the unit to
reduce weight and gain better access to the mounting points to mark them.
III. Installation – Free-Standing
The frame of the unit is suitable to support the system if it is not mounted to a wall. You will need a firm
stable base such as concrete for the system to sit on. Where possible, it is best to fix the system to the
ground or adjacent structure that is already secured. This is to prevent the system tipping over and also to
prevent the system putting pressure on any of the plumbing connections.

IV. Installing Connections – Quick Connect
If you come across a push-fit fitting, you need to firmly push the tubing into the opening until you feel a
“click” which signifies that the tubing has pushed through the internal O-ring and is seated correctly. If
leaking occurs, it may be due to roughly cut tubing OR the tubing is not pushed in far enough. To remove
tubing from push-fit fittings, depress the floating collet (shown to the right), then pull the tubing out. The
LSRO units are fitted with Blue locking
clips. These will need to be removed first
so you can release the fitting. You will also
need to remove them from the fitting if you
are trying to re-install the tubing.
V. Filter Protection
These systems are supplied with an inline Pressure Limiting Valve fitted to the inlet port of the system. This
valve limits the pressure incoming to 50 psi (350 kPa). If your incoming pressure is below 350 kPa, you can
remove the PLV as it may further reduce your incoming pressure.
The system does not come standard with inlet fittings – this should be supplied by the installer unless the
purchaser of the system included fittings in the original purchase.
It is recommended that an anti-water hammer devise is installed on the house to dampen water hammer
commonly caused by washing machines. It is best to install these devices at the point of hammer such as
on the cold-water line at the washing machine or dishwasher for residential applications, or for commercial
applications install near any electric solenoid valves.
VI. Drain/Waste
Reverse Osmosis Systems produce waste water due to the RO process. This water will need to be
discarded in accordance with local government regulations. For applications where the feed water quality is
fair (mains water) the waste water is able to be sent to sewage/septic. NOTE: for septic, consult with the
manufacturer to ensure the increase water discharge is within specification for your septic system. In some
cases where the feed water quality is good, the discharge water may be suitable for utility use and watering
not food plants. It is best to check with the supplier before using the discharge water. If the feed water is
high in salt, the waste water will be concentrated with higher levels of salt and may not be suitable for
discharge into sewage or septic.
If the waste water is not suitable for conventional septic or sewage, you will need to dispose of the water in
a rubble pit or evaporation pit in compliance with local regulations. The waste water should not be allowed
to flow into the environment unless permitted by local authority.
VII. Cartridge Installation
(a) Pre-Filters
Cartridges should be installed in order of: Pleated Before Spun, Spun Before Carbon, Highest Micron
Before Lowest Micron.
As an example, a common filter set would be 5uM Polyspun, 20uM Low Pressure Carbon, 0.5uM
Chloramine Reduction Carbon. You would install them in that order as per the above guideline. Usually We
will invoice the filter in order of installation (reading down the invoice).
Cartridges will need to have the outer plastic shrink wrapping removed before being installed. Maintain
minimal contact with the surface of the carbon filter, handle by the end caps only to avoid contamination as
carbon will absorb smells and oils from the skin.
Gently lower the cartridge into the white sump and locate the filter so the stem in the bottom of the sump
inserts into the centre hole of the cartridge. Do not drop the filter in as this centre stem may break the
plastic caps of the filters. Once the filter is located, screw the sump into the cap (in a vertical position). It
can help to wobble the sump to help the filter locate into the guide lugs in the top of the cap.
The caps should screw up rather smoothly with little resistance so it is usually suitable to firmly hand tighten
the housings. If you encounter resistance before the housing is more than ¾ tightened you may not have

the cartridge aligned with the guide lugs; remove the sump and line it up correctly before tightening. An
opening spanner if provided with these systems and is only required for installation if hand tightening is not
easily achieved or if slight leaking occurs. It is important not to overtighten the housings as this can lead to
excessive stress on the cap thread which may cause damage to the housing long term. The spanner can
be used to help unscrew the housing when filter changes are required as the housings are usually more
difficult to unscrew over time being installed.
(b) Membranes
NOTE: The Membrane filter is not pre-installed. There will be a blue filter cartridge supplied with the
fitting kit that will need to be installed into the membrane housing.
1. Disconnect the tubing from the screw cap end of the membrane housings, check the o-ring to ensure it is
in good condition, if the o-ring gets stuck in the cap – remove it and install it on the housing.
2. Unwrap the Reverse Osmosis Membrane and install it into the membrane housing, ensure that you only
handle the membrane by the end stems. The membrane is inserted into the housing o-rings first so the
stem without the o-rings is visible. Replace the membrane cap firmly but do not overtighten.
(c) Post Filters
These filters are generally pre-installed. When you need to replace them, simply disconnect the tubing from
each end and remove the fittings from the filter. Replace the fittings into the new cartridge then re-install.
Connecting the System
I. Tubing
Measure a length of tubing (White 3/8”) from the feed water connection to the system. Cut the tubing using
poly cutters or a sharp box cutter. Ensure that it is a clean straight cut with no rough edges.
Measure a length of Black ¼” tubing from the drain valve (located behind the micro computer) which is
marked as ‘to drain’ or ‘Flow 800’ to a suitable drainage point.
Measure a length of Blue ¼” tubing from the outlet point of the system to your intended usage point or
storage.
II. Power
The system is supplied with a 2 pin AU plug. Install this into a GPO (10A min). It is advised to also install a
surge protector to protect the electrical components of the system in the event of a power surge or
blackout. NOTE: If there is any damage to the cord DO NOT install – contact the manufacturer immediately
Start Up & Operation
I. Micro-Computer Instructions
SAC Indication: “SAC” will flash on the display when the water supply has stopped
FSH Indication: “FSH” will flash on the display when the system is flushing
PRO Indication: “PRO” will flash on the display when the system is producing pure water. After 4
minutes “PRO” and the TDS value will alternate
FUL Indication: “FUL” will flash on the display when the tank is full. After 10 sec the “FUL” and TDS
. value will alternate
Light 1: Light is blinking when filter 1 is due for replacement
Light 2: Light is blinking when filter 2 is due for replacement
Light 3: Light is blinking when filter 3 is due for replacement
Light 4: Light is blinking when the RO membrane requires replacement
Light 5: Light is blinking when Post (Final) filter requires replacement (if Applicable)
SET Button: Used to modify settings on Micro-Computer ,Change filter times and TDS Setting
Zero Button: For resetting filter change reminder & adjusting filter change times and TDS Setting
TDS Display: Shows TDS of pure filtered water, shows Replacement time and TDS setting
“ “ Light: Light is on when TDS is below set value – System operating correctly.
“ ! “ Light: Light is on when TDS is above set value – Change Membranes

(b) Functionality Instructions
1. After completed installation, the LED will show “FSH” and the system will flush the membranes for
15 sec. After flushing the system will start to produce RO water, the micro controller will start to
display a TDS value after 4 minutes
2. When the Storage tank is full OR the system becomes a closed circuit (by turning off the outlet line
using a tap), the TDS will stop detecting. The “FSH” will display on screen, then the system will
trigger an automatic flush lasting for 15 seconds. During this flush cycle, you must maintain inlet
(source) water so the system has a supply of water for flushing. After flushing “FUL” will display on
screen for 10 sec
3. When the Storage tank is empty OR the System becomes an open circuit (by opening the outlet
valve or tap) the high-pressure switch will be delayed for 25 seconds before starting the flush
process, then will begin to produce pure water. The high-pressure switch will be switched on and off
which will cause the electromagnetic valve to open and shut (this will make an audible noise).
4. When the source (influent) water is stopped, the low-pressure switch will delay for 10 seconds
before triggering the system to shut down. This delay prevents over pressurisation when the flow
rate is insufficient. To prevent such things from happening, the low-pressure switch will turn on and
off triggering the solenoid valve to do the same (this will make an audible noise). During this delay
period, if the influent water is turned back on, it will cancel the shut off process. When the influent
water has stopped, this will also cease the TDS from being detected.
(c) Preview Default Settings:
1. First, press and hold the Setup button for 2 seconds, this will display the first setting mode. The LED
will show 103 and light 1 will begin to blink. Factory settings are 103 which indicate that the first filter
replacement is sent to alarm every 3 months. The first digit signifies the filter number and the last 2
digits signify the month.
2. Press the Setup button to bring up the filter 2 timer. It will show 206 and light 2 will blink. The factory
setting for 206 means the 2nd filter replacement reminder alarm is set to 6 months
3. Press the Setup button to bring up the filter 3 time. It will show 306 and light 3 will blink. The factory
setting for 306 means the 3rd filter replacement reminder alarm is set to 6 months
4. Press the Setup button to bring up the filter 4 time. The LED display will show 075 and light 4 will
begin to blink. 075 indicates the TDS limit of the RO membranes. This means when the TDS is
above 75 ppm, the replacement change light will blink and the membranes will require replacement.
5. Press the Setup button to bring up the filter 5 time (post filter). It will show 512 and light 5 will blink.
The factory setting for 512 means the 5th filter replacement reminder alarm is set to 12 months
6. If you want to return to original settings, hold the Setup button again for 2 seconds and wait for the
“Beep, Beep”.
7. If you need to change multiple settings, do them all in sequence then press and hold the Setup
Button for 2 seconds and wait for the “Beep, Beep” to complete all the settings.
(d) Changing computer Settings:
For applications where the influent water is municipal and free from most sediments, you can extend the
replacement warning for filter 1 to 6 months. To do this, Press and hold “SET” key for 2 seconds, then
proceed by entering the 1st setting mode. The LED display will show 103 and filter 1 light will begin to flash,
Press “ZERO” key then the number on the LED display will count up from 103 -> 104 ->105 and finally 106.
Press and hold the “SET” button for 2 second and wait for a “beep” two times. If you do not confirm the
settings by holding down the Setup Button for 2 seconds, the settings will not be confirmed and they will
stay the same.
The time alteration procedure is identical for filters 2,3,4,5 as above
(e) Automatic Reminder Instructions:
When the system is alarming for a filter change, the filter replacement light will begin to flash and the alarm
will sound. Each time water production starts, the alarm will sound for 1:30 minutes. This will occur every
time until the filter reminder has been reset.
When the filters have been replaced, hold down the “ZERO” Button for two seconds until you hear 2 beeps.
The filter replacement light will shut off and the timer will reset.

NOTE: When you replace the new RO membrane, the TDS value may be higher than the alarm setting.
This is due to the chemical preservatives inside the membrane. After adequate flushing, this sanitiser will
be removed and the TDS will stabilise to normal levels. Due to this, the Micro-Computer alarm has a 4-day
delay. If the TDS has not stabilised after 4 days, please contact the manufacturer.
II. Commissioning
NOTE: New filtration systems will require a pre-flush before being used. The GT1-23LS system will need to
run for at least 15 – 20 minutes before first use to clear and residue or fines from the filters.
•Use a TDS meter to monitor the water to determine when the system is suitable for the intended
application.
•When the system is connected correctly, turn on the incoming water supply and allow the first filter
cartridge to fill with water. Once this has stabilised, turn on the power to the system.
•Turning the power on will actuate the inlet solenoid valve and the water will then begin to pass
through the remaining 2 pre-filters then to the membrane.
oThe pump will turn on at this point – the working pressure gauge will remain at 0 until the
water reaches the membranes.
•Once the water reaches the membranes, the drain line should begin to sputter and produce water –
it is normal for this to be cloudy and discoloured on first use.
•At this point, the water will then need to slowly pass through the membrane and post filter so the
system will need to run for several minutes until water will begin to flow.
Your water is now suitable for use.
III. General Operation
The rating of this Reverse Osmosis system is 100GPD as per the membrane specifications meaning this
system is capable of approx. 15L/Hour of water production, this will vary depending on water quality and a
number of factors. The systems are designed to be run in a closed loop configuration where the system
runs off a float switch or timer, this type of configuration allows for system downtime and helps extend the
lifespan of the pump as the system is intermittently producing water
When the system is installed in an open loop configuration and the pump hasn’t been allowed any
downtime you may expect to see a decrease in the pumps lifespan due to overheating. If you intend to use
the system this way please contact us as we may have a better solution for your specific circumstance
Production scenario for closed loop configuration – The system is run for up to 8hrs a day (intermittently
with down-time for cooling pump), in this configuration the system will produce approx. 125L +/- per day.
This is the recommended runtime scenario specified by the manufacturer for extended pump lifespan
Production scenario for open loop configuration – The system is run for continuously without a cool down
period, in this configuration the system will produce approx. 375L +/- per day. This is the maximum
capacity of what this system can produce however this may also decrease pump lifespan*
*Note: the pumps come with a 90-day replacement guarantee/12-month pro-rata warranty per pump from
date of invoice. If the pump fails within the first 90 days of operation, we will replace it, if it fails from 90-365
days, we will cover it on a pro-rata basis. The pumps as well as the filters are classed as a consumable
item
IV. Automation
The system is fitted with high and low-pressure switches. This will allow the system to know when to shut
off due to the tank being full, or the feed water has been shut off.
When power and water is connected to the system and the outlet is open, the system will automatically
produce water. When the outlet shuts off, the high-pressure switch will trip after a period of time (similar to
a household pump) and then the system will shut down. When the outlet is opened and the pressure falls
below the limit, the system will start up again.
Similarly, when the feed water is cut off to the system, the low-pressure switch will trip and the system will
shut off after a few seconds.

If installing this system to a float switch in a tank, you will need to disconnect the high-pressure switch and
connect the float valve terminals in its place. This will then run the shut off based on the float rather than
the pressure.
TIP: If the system needs to be shut down and serviced, a handy tip is to shut off the inlet water supply and
allow the pressure to bleed out (few seconds) before shutting off the power. This will make it much easier to
disconnect any fittings.
Maintenance
I. Replacement Parts
A list of replacement parts is listed below with their corresponding recommended lifespan for replacement.
II. Replacement Cartridges
On Municipal water supplied, the pre-filters should be changed every 20,000L (300 Hours constant Run
Time) OR 6 Months, whichever occurs first.
Post Filter:
This filter should be changed per the manufacturers recommendations.
DI Resin:
Due to the nature of resins and the variance of water quality, this media will also need to be monitored with
a TDS pen or meter to determine when the filter media has expired. DI resin will extract residual ions from
the water reducing the RO water back to a 0 TDS reading. The filter media will require changing once the
TDS exceeds your required limit. To change the DI media:
•Inline DI Filter: Disconnect the tubing from the inline filter and remove the filter from its mounting
clamps. Unscrew the end cap in an upright position and remove the sediment pad and o- ring to
avoid getting debris on the o-ring seal. Discard the filter media and rinse the cartridge with clean
water, removing and remaining DI resin. Refill the housing with resin, replace the pad and o-ring
and replace the head cap.

Unseated tubing
Check all tubing connections by firmly pushing them into the
fitting. Check that there are no kinks or any obvious issues. If
the problem persists, remove the tubing and check for a
clean cut with no burs. Push the tubing back in and try again.
If this does not work please contact customer support.

2. Individually remove each filter 1 at a time to determine at
which point the water is unable to pass. Check to ensure that
the filters are installed correctly in a vertical position and that
they are unwrapped.
3. These systems require a minimum feed pressure of 350
kPa to function correctly. <350 kPa may work however the
pump may have issues with priming and may not be able to
reach its full working pressure.
4. Ensure that your feed water does not exceed the
specifications of the RO system. If your water contains higher
levels of impurities, your membranes could be scaled and
may need cleaning or replacing.
5. Check for obstructions of blockages. Check that the switch
on the float valve actuates correctly.
6. the pressure is either insufficient, or the inlet solenoid
valve may be damaged or faulty not allowing the water to
pass through.
High pH reading
1. GAC Filter
2. Insufficient Testing
Equipment
1. If you have a GAC or Block filter (Carbon), this will
naturally increase the pH of the water. pH is the measure of
Hydrogen in the water and this hydrogen will vent off the
water if you leave it to stand and the pH will then drop back
down to the normal level.
2. pH testing equipment can range from a cheap test pen
right up to lab grade equipment. Before coming to a
conclusion on pH issues, it is best to ensure the equipment
used to measure the pH of the filtered water is of high
standards and suitable for reading pH levels in lower EC
water (i.e. The guy at the pool shop is not going to cut it). We
have access to high quality testing equipment and frequently
test our units and conduct research. If you feel that there is
an issue with your pH, please contact us.
Strange taste to
the water (New
System)
1. Residue
2. pH Alteration
3. Contamination
1. The filters are dry packed, the carbons, alkaline filters will
have ‘fines’ on them.
2. As previously stated, Activated Coconut carbon will react
with the water when new and will increase the pH. People
who are not accustomed to higher pH water may notice a
strange taste/sensation due to the large variance of pH.
Flushing the system will help stabilise the pH from the system
and also allowing the water to stand before drinking can also
help allowing the water to ‘vent’ the pH
3. Bacterial contamination is highly unlikely, but not
impossible. If there is a strong ‘foul smell’ or organic taste to
the water, it is possible that there is some form of
contamination. Contact us straight away so we can rectify (or
diagnose) the problem if there is one present.

The TDS Is
Higher than the
inlet water (or
the same).
1. New Filter
2. No Effect on
Dissolved salts
1. While filters are new, it is normal for the TDS to be
elevated while the system is flushing. Continue flushing the
system & contact support if the high TDS persists longer than
1 week.
2. Standard filtration has little to no affect at reducing the
salts in the water. In some cased the TDS can reduce
however it is not uncommon for the TDS to stay the same or
slightly rise (as the system in new) due to the fines from the
filter.
Flow has
suddenly
slowed down to
a trickle
1. Blocked filters
1. Check the feed water conditions & cartridges and replace
the filters if they are passed the recommended change times.
Pumps Stopped
working
1. Damaged or worn
out pump
2. Power Supplies
Faulty
1. The pump may require replacing if it has been overworked
outside the manufacturer’s guidelines.
2. Power surges may cause the power supply to short out.
Other things include water leaking or overheating. An
electrician can test the components to see if power is making
it to the pumps.
