1.0 Introduction
This guide provides the information required to install, use and maintain the BRAC Systems RGW
series residential grey water recycling system. Carefully read these instructions and complete the
installation checklist, this will ensure that the grey water recycling system is installed correctly and
safely. Leave these instructions near the system after installation for future reference.
When integrated into the plumbing of your home, the RGW system captures the water used in your
shower, bathtub and laundry machine (if allowed) and recycles it to flush your toilets.
The grey water from your shower, bath and laundry enters the RGW system through the grey wa-
ter inlet pipe where it passes through a 100-micron pleated cartridge filter, and collects in the lower
portion of the RGW system tank. A 3” overflow pipe connected to your sewer line prevents the tank
from overfilling.
A potable water inlet pipe controlled by an electronic pressure sensor and solenoid valve, assures a
minimum level of water in the tank, preventing the pump from running dry and making sure there is
always water to flush your toilets.
The collected water is drawn through a foot valve by a pump which provides grey water at pressure
through the grey water outlet, supplying grey water to your toilets and if allowed, a closed loop ir-
rigation system.
An electronic chlorination system circulates the grey water through a separate chlorinator valve at
programmable intervals, allowing the grey water to be treated to a safe level without becoming over-
chlorinated.
The RGW series requires a connection to your home’s sanitary drain and should only be installed by
a licensed plumber. We recommend that your plumber also install a fresh water bypass and shut-off
valve to provide backup clean water to your toilets in the event of a power failure or should your sys-
tem require removal for servicing. We also recommend a grey water bypass overflow and shut-off
valve so that in the event of a filter obstruction, your bath and shower drains will not back up.
Laundry Option:
Check local plumbing codes If the laundry option is allowed in your jurisdiction. While laundry water
is suitable for reuse, the presence of lint may increase the frequency of filter cleaning required. If
using laundry water as a grey water source, BRAC Systems offers a prefilter that will increase the
duty cycle of the primary filter. Contact your local BRAC Systems service representative for more
information.
Research and testing has shown that in the average household, with each member taking an aver-
age of one shower per day, sufficient quantities of grey water are generated by bathing alone to
match the amount of average flushes per day in the same household. So you may choose to omit
capturing the laundry water when installing your system.
You may also consider installing both a traditional drain alongside a grey water drain to the RGW
system behind your laundry machine. This will allow you to include or exclude your laundry water
from grey water collection simply by moving the hooked drain hose behind your washer from one
hole to the other. Be sure to refasten the hose securely.

Power Transformer:
Connect the 24V DC power transformer to the AC power cord. Connect the 24V DC jack into the
corresponding slot marked “ELECTRICITY” found on the outside of the upper portion of the RGW
system. Do not connect the AC power cord to the AC outlet at this time.
Clean Out Drain Valve:
The clean out drain valve is a 1” socket and 1" male threaded PVC ball valve and is included in the
installation kit. Apply Teflon to the male threads of ball valve and screw into the bottom of the tank by
hand until it is snug, being careful not to cross-thread. Orientate so the valve handle is on top.
Suction Foot Valve Unit :
This assembly is identified by a plastic foot valve on one end and a grey PVC elbow with a
stainless steel flange attached at the other end. Remove two bolts and rubber gasket from
the side of the pump. Fill the pipe with approximately 2 liters (.5 gal.) of water through the
elbow. Place the foot valve end of the pipe through the 2” hole closest to the centre of the
black platform disk and lower the pipe until the steel flange aligns with the corresponding
mating surface on the pump.
Press the black rubber grommet found on the pipe, into the 2” hole on the black support
disc to make the proper seal. Securely attach the flange and gasket to the pump with the
two bolts using a 12 mm wrench.
Water Level Sensor Unit:
This assembly is identified is identified as a long grey pipe with an electrical wire and con-
nector exiting from one end. Use the yellow rubber gasket (supplied) and gently slide it over
the pipe up against the PVC flange. Place the end opposite of the wires through the 1-3/8”
hole near the edge of the platform disk and lower the pipe until the PVC flange rests on the
black support plate. Secure with three Phillips screws (supplied) using a Phillips head screw-
driver. Connect the level sensor pipe’s electrical connector to the vacant connector on the
wiring harness.

8.0 Installation
Plumbing codes vary by jurisdiction. Your certified plumber will know the codes for your area. These
notes are provided for informational purposes only and as a general guide for your plumber to fol-
low. Cross Connection Control Devices (CCCD) is a generic term that refers to devices or methods
that prevent potable water supplies from being contaminated by non-potable water. A CCCD can
be as simple as an air gap, or as complex as a Reduced Pressure Back Flow Assembly (RPBA).
Other common types of CCCD’s include Double Check Valve Assemblies (DCVA) and simple check
valves. Your local plumbing official will determine which type of CCCD is required for your particular
installation.
Position the RGW system in a location so that all connections will remain accessible.1.
Calculate the fixture units for the tubs and showers that will drain into the RGW system, then size2.
the inlet, vent and overflow pipes accordingly. Adapters with threaded union fittings can be used
on the grey water inlet and overflow outlet to allow the RGW system to be connected or discon-
nected from the plumbing system.
Following local plumbing codes, connect the drain lines from the fixtures to the grey water inlet3.
port of the RGW system. Install a bypass and vent pipe to the overflow drain. For bypass piping,
install a WYE upstream of the grey water ball valve 16" vertically with a minimum of 6” horizon-
tally between the bypass and vent WYE. Then connect to the overflow piping upstream of the
backwater valve. The 6” horizontal length will prevent the loss of grey water through the bypass
during normal operation. (See figure 5).
Install a P-Trap and an approved backwater valve (such as a swing check valve) down stream4.
of the overflow port and connect the overflow pipe directly to the building drain. (See figure 1).
Local codes may require that the overflow piping be indirectly connected to the building drain. If
so, run the drainpipe so that it will terminate above an open running trap, such as a floor drain.
Be sure to provide the proper air break distance. Your local plumbing official will determine what
type of connection has to be made to the building drain.
The vent port must terminate to open air, or be connected to another vent that terminates to5.
open air. (See figure 5).
If local codes require, Install an approved cross connection control device (CCCD) on the po-6.
table water pipe to the “fresh water in” port of the RGW system. (See figure 5).
For reasons such as power failure, it is recommended that a bypass line with shut-off valves be7.
installed between the potable water in and the grey water out lines, downstream of the CCCD.
This will ensure that the toilets are supplied with pressurized water for normal operations at all
times. (See figure 5).
Connect the potable water line to the 3/4" MPT fitting on the RGW system labeled "Fresh Water8.
In"
Connect the grey water supply line to the 3/4" MPT fitting on the RGW system labeled "Grey9.
Water Out"
It is recommended that a standard hose bibb be installed on the grey water outlet piping down-10.
stream of the shut-off valve. (See figure 5). This faucet could provide water at pressure for use
in a closed loop irrigation system (if allowed) and can also used to prime the system pump and
release system pressure prior to servicing the pump.

10.0 Priming and Start-Up
After the RGW system has been completely installed, follow these steps to prime and power up the
system.
Open the ball valve on the freshwater IN pipe to allow the line to pressurize.1.
Plug in the power transformer AC cord to a wall outlet and connect the 24V DC jack to the RGW2.
system. The fresh water solenoid valve should open and the tank should begin to fill with clean
water. When the water level reaches the minimum amount required for the pump to operate
safely, approximately 38 liters, (10 USG) the valve will automatically close and shut-off the fresh
water supply. Make sure the suction pipe has been filled with water prior to installing.
Remove the small red cap from the top of the pump housing. Fill the small compartment re-3.
vealed under the red cap with water then replace the cap. (See figure A).
Tip: If a freshwater bypass line has been installed, slowly open the bypass shut-off valve to allow the
lines to pressurize. Place a bucket under or connect a short hose to the external irrigation/priming
faucet and open the faucet to expel any remaining air in the lines. Close the bypass shut-off valve.
Plug in the pump’s AC power cord. The pump should begin drawing water and pressurizing the4.
service lines. Once the pump is primed and the grey water OUT line is pressurized, it will take 8
seconds before the pump shuts off. If the pump fails to prime, unplug the pump, and repeat the
three previous steps. Do not let the pump continuously run when not primed. It may take multiple
repeats of this step to get the pump primed. Use the above tip if possible.
Place a bucket under or connect a short hose to the external irrigation faucet, if installed, and5.
slowly open the faucet to test for adequate flow and proper pump function. This will also release
any additional air trapped in the system.
If the pump fails to start or stop, the factory set pressure switch may need to be adjusted. The in-
structions for the location and adjustments of the pressure switch can be found in the pump manual
(Section 12.0)
Flush the toilet furthest away from the RWG system to test it's function and to release any air
trapped in the service lines. Then flush all additional toilets to test their functionality.
If you are still experiencing problems with the start-up procedures and have followed all instructions
thoroughly contact your BRAC Systems service representative.

11.0 BC-100 Controller
Your RGW series system is equipped with the BC-100 water management controller.
The BC-100 controller in your system has been pre-set to manage the grey water throughout the
day for optimal disinfection. There are 16 possible settings ranging from No Extra Chlorination (twice
per day chlorination) to Maximum Chlorination. The default setting is Level 6 Chlorination, which will
keep optimal levels of chlorine in the grey water based on daily flow volumes of 250 liters (66 USG).
If more or less daily flow volumes are expected, the dip switch settings on the BC-100 controller
should be adjusted accordingly. Each setting will increase or decrease the chlorine level by 0.5 ppm.
(Parts per million) (See the chart below for chlorination level settings)
The BC-100 controller will process the grey water at a minimum twice per day every 12 hours based
on the quantity of water in the holding tank. If the switch setting is set to minimal chlorination or
more, the system will monitor in real time the grey water entering the system and will process on an
ongoing basis to insure proper water quality. If the system is unused for more than 12 hours, the
system will enter “vacation mode” and will process the grey water to optimize the resources such as
electricity, water and chlorine.
Please take note that regardless of the chlorination level setting, the system will process the wa-
ter at a minimum of every 12 hours. The system clock starts at 0 hour when powered on. To avoid
pump starts during the night, we recommend that the unit be powered ON between 6-10 AM or 6-10
PM. This way, the system will go through its water processing cycles at more convenient times for
the household.
The enabled LED should be green to show that the system is operational. If the LED flashes, this
indicates that water level sensor has not been connected.
The chlorination cycle can also be manually operated by pressing the blue “Chlorinator” button
on the BC-100 controller. The chlorination valve will operate only while the “Chlorinator” button is
pressed. Once you release the button, the chlorination valve will close. The “Chlorinator” button
should not need to be pressed for more than one minute at a time.
The fresh water make-up circuit is automatically managed by the BC-100 controller. It too can be
manually operated by pressing the blue “Fresh Water” button on the BC-100 controller. The fresh
water make-up valve will operate only while the “Fresh Water” button is pressed. Once you release
the button, the fresh water make-up valve will close. The “Fresh Water” button should not need to be
pressed for more than one minute at a time.
Warning: Do not depress the blue buttons on the BC-100 controller for an extended period of time.
This could cause damage to the controller.

12.0 Pump Manual
Operating conditions:
1. Ambient temp: Max. + 40oC (104oF)
2. Liquid Temp: + 4oC (39oF) ~ + 40oC (104oF) Max.
3. System pressure: Max. 120 psi
4. Relative humidity: Max. 85% (RH)
Ensure the mains voltage is the same as the value shown on the motor plate and that the pump is
safely connected to ground.
Precautions:
1. The pump should be shut down and the trouble corrected if the pump is running at speed and
found to have any of the following problems:
No liquid discharged - Not enough liquid discharged – Excessive vibration – Motor runs hot.
2. Do not allow pump to continually start/stop (cycling). This will reduce motor life.
3. Cycling can occur on pressure units when pressure tank pre-charge drops or when there is a leak
in the discharge plumbing.
4. Pressure tank pre-charge should be checked at regular intervals of every 3 months and after
the pump has not been used for a prolonged period. To check the pressure tank air pressure turn
off power, open a tap on the discharge line to release pressure from the pump, unscrew the black
plastic cover and apply an accurate pressure gauge to the valve. Pressure should be adjusted to the
original pre-charge as follows: TQ400: 24 psi (1.7 Kg/cm2) - TQ800: 28 psi (2.0 Kg/cm2)
Maintenance:
Under normal operating conditions, the pump does not require any maintenance as long as the fol-
lowing points are observed:
1. Periodically check the condition of the check valve located under the red fill cap. Remove the
prime cover to check the condition of the check valve.
2. Periodically check the condition of the pump strainer located on the inlet of the pump. Remove
the two flange bolts from the suction pipe assembly to access the strainer.
3. If the pump sticks after periods of inactivity, a screwdriver slot is provided on the motor shaft end
to free up the pump/motor. To do so, insert a screwdriver in the slot in the motor shaft and turn to
free the rotor.
Adjusting the flow and pressure switch:
The pump is supplied with a preset pressure and flow switch. In some cases a different pressure or
flow may be required.
Flow switch: Remove the hex screw using a 5mm Allen key.
Insert a Phillips screw driver into the hole and turn clockwise. Make sure the system is primed.
Pressure switch: Remove three Phillips screws on the pump cover. Remove the cover. Insert a Phil-
lips screw driver on to screw on the pressure switch.
1. If pump does not start when priming faucet is open, adjust clockwise (+) until it starts.
2. If pump does not stop when priming faucet is closed, adjust counter-clockwise (-) until it stops.
3. After adjustment is made, open and close priming faucet several times to make sure the pump
operates normally.

14.0 Maintenance
There are four main areas of routine maintenance that must be attended to:
•Chlorinatingsystem
•Filtercleaning
•PumpScreenCleaning
•Tankcleaning
Chlorinating System
When left untreated, grey water can quickly turn to black water. The BRAC RGW System features
an automated programmable chlorinating system, which circulates the grey water in the holding
tanks through the chlorinator and back through the filter housings at pre-programmed intervals.
While the timer controlling this system is preset at the factory, proper chlorinating requires the user
to visually inspect the chlorinator for remaining tablets, and replace when necessary. This is most
conveniently done during the filter cleaning procedure. (See next section – “Filter Cleaning”).
The chlorinator is located in the upper portion of the tank and is visible when the lid is removed.
When the chlorine tablet supply is getting low, simply remove the threaded cap of the chlorinator by
turning counter-clockwise.
Warning:
Do not inhale the chlorine gas when removing the chlorinator lid as serious injury may occur!
Following the manufacturers Calcium Hypochlorite handling instructions, refill the chlorinator. The
chlorinator will hold eight (8) 140-gram (5oz.) tablets. Replace the chlorinator lid and tighten se-
curely. We recommend that the NORWECO brand “Bio Sanitizer” Calcium Hypochlorite disinfecting
tablets be used.
Some jurisdictions require that grey water be dyed blue or green before being served to toilet fix-
tures. In this case, contact your BRAC Systems representative for information on our BDD-30 Blue
Dye Dispensing Unit.
Filter Cleaning
As we are unable to determine the exact grey water inflow volumes for each application, we recom-
mend that you inspect and clean the filters every week. If you realize that the build up of residue in
the filters does not warrant cleaning the filters every week, we recommend that you decrease the
frequency of inspecting and cleaning of the filters by three days at a time, every ten days, every
thirteen days, every sixteen days and so on, until you determine the proper time interval for your
particular situation. (See figure 6 page 18)
Also bear in mind that the capture of laundry water will cause the filter to clog more frequently due to
laundry lint.
Procedure:
If the potable water bypass is installed, open the bypass valve to allow the toilets to operate on1.
potable water during this procedure.
If the grey water bypass is installed, close the bypass valve to divert the grey water to the sewer2.
during this procedure. If a grey water bypass has not been installed, do not use the bath, shower
or laundry while cleaning the filter.

Replace the RGW system lid.13.
Close the potable bypass valve, if applicable.14.
Open the grey water bypass valve, if applicable.15.
Plug in transformer and power cable.16.
If the filter is damaged and has to be replaced, please use the extra filter which has been supplied
by BRAC Systems.
If there is a tear or hole in the filter the tanks should be cleaned out. We recommend that you pur-
chase replacement filters from your BRAC Systems dealer, so that you always have an extra filter
on hand.
Tip:
Some users have found it convenient to alternate the use of the factory-installed filter and the extra
filter provided at each cleaning procedure.
There are also cartridge filter cleaning devices on the market that are used to clean the filters for hot
tubs and pools. These will work to clean our filters and can be found at most pool supply vendors.

Disconnect the pump AC power cord from the mains supply.
Remove the system lid. Locate the connection of the suc-
tion pipe unit on the side of the pump identified by the steel
flange with two bolts and grey elbow.
Using a 12mm wrench, loosen and remove the two bolts
connecting the steel flange to the pump. Gently manoeuvre
the suction pipe unit to allow access to the black rubber gas-
ket containing the strainer screen.
Inspect the strainer screen for material build up. If the
strainer screen is clean, no further action is necessary and
the flange can be replaced onto the pump and the two bolts
inserted and tightened.
Remove the gasket from the flange and take out the strainer
screen. The strainer screen can be cleaned or replaced and
inserted back into the gasket. Replace the gasket and flange
of the suction pipe unit onto the pump and insert and tight-
ened the two bolts. Replace the system lid. Reconnect the
pump AC power cord to the mains supply.

As we are unable to determine the exact grey water inflow volumes for each application, we recom-
mend that you inspect and clean the pump strainer screen every three months. If you realize that
the build up of material on the strainer screen does not warrant cleaning every three months, we
recommend that you decrease the frequency of inspecting and cleaning of the strainer screen by
one month at a time, until you determine the proper time interval for your particular situation.
NOTE: Do not operate the RGW system without the strainer screen as pump damage could occur.

Tank Cleaning
Note:
It has been our experience that with a properly chlorinated system there will be no sludge build-up
in the bottom of the RGW system. Under normal circumstances, it should be sufficient to clean the
tanks once every six months. Initially, we recommend that you inspect and clean the tank every
three months until you have determined the proper cleaning interval.
WARNING:
If a grey water bypass has not been installed, do not use the bath, shower or laundry while cleaning
the tank.
Procedure:
Unplug the pump AC power cable and the 24V DC power transformer from the power source.1.
If a grey water bypass is installed, close the bypass valve to direct the grey water drainage to the2.

15.0 Frequently Asked Questions
Q. What is grey water?
A. Grey water can be classified into to groups; Light and Dark. Dark grey water is the wastewater
generated from kitchen sinks and dishwashers. It has a Fat, Oil, Grease content (F.O.G.) Light grey
water is the wastewater generated from the use of the shower, bathtub, hand sink, and laundry.
Q. Is grey water different from wastewater?
A. Yes. Household wastewater, also known as sewage, is composed of two distinct sources:
"Black water” is wastewater contaminated by feces or urine, and includes wastewater from the toilet,
urinal, or bidet.
“Grey water” is the remaining wastewater coming from the laundry, bathroom and kitchen.
Q. Why should I reuse grey water?
A. Grey water is a significant water resource, provided it is managed in an environmentally respon-
sible manner, and public health and the health of the household are protected. By capturing grey
water and using it in an appropriate manner as an alternative to your water supply, you can reduce
your water consumption. Your water account will reflect this reduction in water use and there will
also be positive environmental outcomes.
Q. Is it safe to reuse grey water?
A. Yes, when first disinfected and used in an appropriate way. Grey water can contain disease-
causing micro-organisms such as bacteria, protozoa, viruses and parasites. It may also contain fats,
oils, detergents, soaps, salt, nutrients, food and hair derived from household and personal cleaning
activities. These constituents can pose both health and environmental risks. However, the public
health risks associated with on site reuse of domestic grey water are considered low, as the source
of the contamination would be from the immediate family. Other sources of transfer of pathogens
around the immediate family are considered a higher risk, such as direct contact or sharing of food
and utensils. Similarly, the risk of environmental damage from the careful use of grey water is low.
Q. How can I reduce the risks associated with grey water reuse?
A. The following measures will reduce the health and environmental risks associated with the use of
grey water:
Do not use sprinklers to distribute grey water.•
Use subsurface irrigation systems.•
Do not spray grey water directly onto food plants.•
Do not put grey water on lawns where children are likely to play.•
Do not irrigate with grey water during periods of wet weather.•
Do not allow grey water to enter the storm water system.•
Make sure grey water does not create a nuisance, for example through odors or ponding.•
