What to Do if Your Tank is Not Level Out of the Box:
Your black lter tank base is not glued to the bottom of your tank. Occasionally tank bases will
become crooked during shipment. If you nd that that your tank does not sit level on the oor,
you can easily adjust it by holding the empty tank and knocking it on a concrete or solid oor
once or twice to level it.

Pre-Installation
1. Review your packing list and make sure you have received all the parts before installation.
2. If you are going to be turning o the water to the house and you have an electric water
heater, shut o the power to the water heater before beginning installation in case water
heater is accidentally drained.
3. Pick a suitable location for your lter system on a dry level spot where it won’t be exposed to
freezing temperatures. A minimum of 30 PSI is required. Maximum pressure is 90 PSI.
4. Get all of your plumbing parts together before beginning installation, and make sure you
have received all of your packages before beginning or scheduling an installation. Installation
typically takes 3 to 5 hours. However, after installation the Turbidex Backwash Filter must be
allowed to run through a complete backwash and rinse cycle.
5. After the system is installed and running, your water may be discolored, or full of sediment or
rust, particularly if this is older or corroded piping. This typically clears up over a day or two.
Best Practices for Piping & Drain Installation
1. Make sure to connect the Inlet from your water source and outlet, following arrows on
control valve.
2. Make sure there is a gate or ball valve before and after the lter system.
3. A hose bib (which is a faucet to which you can attach a garden hose) is strongly
recommended after the Sediment Backwash Filter and before the second ball valve. This
makes it easy to rinse your new Sediment Backwash Filter on start-up and gives you a place
to test the water.
4. If you will be using copper piping, do not sweat the copper pipe
directly on to the 7500-REV2.5 control valve.
5. To connect drain line to drain, use an air-gap connection, so that if
your sewer or septic tank backs up, it cannot cross connect with the
drain tubing.
6. The pipe connectors are 1’ male pipe thread but you can add a reducer
to reduce to ¾” pipe with common pipe ttings if needed.

How the Bypass
Valve Works
Turn knob so the valve is bypassed
when installing.
Installation of Your System with Copper
or Metal Piping Systems
If your new lter system is to be installed in a metal (conductive) plumbing system, i.e.,
copper, or galvanized steel pipe, the plastic components of the system will interrupt the
electrical continuity of the plumbing system.
As a result, any stray currents from improperly grounded appliances downstream or
potential galvanic activity in the plumbing system can no longer ground through the
contiguous metal plumbing.
Some homes may have been built in accordance with building codes, which encouraged the
grounding of electrical appliances through the plumbing system.
Consequently, the installation of a bypass consisting of the same material as the existing
plumbing, or a grounded “jumper wire” bridging the equipment and reestablishing the
contiguous conductive nature of the plumbing system must be installed prior to your
systems use.
This is simple and easy step to take if you are installing your water treatment system into
copper piping.
A simple ground jumper wire with a pipe clamp can be purchased at any Home Center, or
hardware store etc. for a few dollars.

How Your Sediment
Backwash Filter Works
Water enters the top of the tank and ows down
through the media and up the distributor tube.
The backwashing Sediment Backwash Filter
removes sediment and is automatically
backwashed.
This cleans and re-classies the Turbidex lter
media, preventing channeling.
During backwash the ow of water is reversed
and water ows down the distributor tube and
up through the media, lifting and expanding the
Turbidex media.
During the backwash the Turbidex is cleaned by
the action of the water owing through the media
and rinsing out sediment to drain.

Tank Assembly and
Installation Instructions
1. Make sure no media enter distributor tube by covering the top
of distributor tube with tape. If are you using a black funnel with
distributor tube cap built-in to the funnel, no need to use tape.
2. Make sure you “test t” distributor tube, nd divot that keeps
tube centered, before adding gravel so distributor tube does
not extend past top of tank.
3. Add all the lter gravel that came with your order.
4. Next add Turbidex media. The tank should be about 2/3rds full of media, do not ll more
than 2/3rds, even if there is some media left over.
5. Remove tape from top of distributor tube. Be careful not to pull up distributor tube.
6. Add ¼ cup of household bleach (optional) and ll tank completely with water. This will allow
the Sediment Backwash Filter media to settle and reduce the need of purging the air out of
the tank later. Allow Turbidex to soak for at least 1 hour but 24 hours or more is OK. Turbidex
contains trapped air will help clear this out and prevent dry media from entering the control
valve during the initial backwash.
7. Add a small amount of silicone grease (sent with
your order) to the inner O-ring, where distributor tube goes.
8. NOTE: Your Sediment Backwash lter does not use a top screen. If you are looking for a top
screen, there isn’t one provided, it is not needed or recommended.
9. Lubricate the main tank O-ring with silicone grease and
screw on the 7500-REV2.5 control valve carefully. Do
not use pipe-joint compound, vegetable oil, Teon tape,
or Vaseline or other petroleum greases to lubricate
tank threads.
10. Connect bypass assembly with 1” pipe connectors to
control valve, making sure Inlet and Outlet is correct.
11. Insert meter cable into meter cable port on bypass.
12. Install inlet and outlet piping and hook up drain line
tubing to drain.

13. If you are in earthquake zone, strap
your backwash lter tank to wall
with metal strapping.
14. Proceed to programming your
7500-REV2.5 control valve timer and
backwash frequency.
IMPORTANT: you must program the
time and then start a backwash
and rinse. The lter system must
be backwashed and rinsed several
times before using. See following
pages for instructions.

Review Software Version Version 5.0
Start the First Backwash
1. After programming, the system must be run through 2 or 3 backwash/rinse regeneration
cycles to clean the new lter media.
2. Start with bypass valve in the closed or bypass position.
3. Press the BACK/REGEN button once to enter the backwashing cycle.
4. When the display shows the valve in backwash position, open the bypass knob until you hear
the water going through. Now, wait for the water to start coming out the drain line- it will
come out slowly, and may have some air in it.
5. Wait 2 minutes, and open to a quarter turn, note the increase in ow. Wait two minutes, go to
Half open, wait two minutes and go to Full open (there will be a bit less than 2 minutes left on
the ten-minute cycle). If the water continues to ow out the drain, then let the cycle nish and
do the rinse and then return to service.
6. If you see the Turbidex media itself coming out of the drain line in a slurry during the
startup back wash, CLOSE THE BYPASS KNOB IMMEDIATELY. Make sure that the proper
Drain Line Flow Control button is installed.
7. Now, open the hose bib after the lter and run for a minute, or until any air has nished
coming out. Next, starting with the bypass full open, start and run 2-3 more backwashes,
running some water out the tap after the lter in between each backwash.

8. The backwash is now counting down from 10 minutes- you want to keep it in backwash for a
while, so unplug the power supply from the wall, and the valve will stay in backwash.
9. Open the bypass a bit more, and conrm you have a bit more ow out the drain line. Wait
ve minutes. Open the valve a bit more, let it run for ten minutes. Do that a couple more
times, until the valve is full open.
10. Each time you open the bypass valve more, the ow out the drain line should increase.
Immediately close the bypass if you see media coming out the drain line.
11. If possible, verify that the backwash ow corresponds with the size of your system below.
12. You can easily run the drain hose to a bucket and using a watch verify the approximate ow
rate in gallons per minute. An adequate backwash is critical to properly clean the Turbidex
media. For example, if the backwash water lls a 5-gallon bucket in 1 minute, you have 5
gallons per minute (GPM).
13. After the backwash, the system will automatically go into the fast rinse stage. The control
valve will return to service status (indicated by the up owing meter on the left) after the
backwash and rinse are complete.
14. Repeat the Regeneration (backwash and rapid rinse cycle) step 2 to 3 more times until you
see clear water through the drain line or your hose bib.
15. Finally open the closed ball valve after the system to allow water to ow to house. Water may
be discolored at rst if pipes had some scale or sediment. Run water to rinse pipes.

Maintenance
Every 4 to 6 years (in some cases it can last longer) remove control valve and empty lter media
and replace with new media.
There is no routine maintenance required for the control valve or lter media, other than
making sure the system is set to backwash frequently enough to keep the lter media clean.
If you notice a pressure loss you might consider changing the backwash to every 2 or 3 or in
some cases every day if there is a lot of sediment (also depends on amount of water you
are using).
Troubleshooting the 7500-REV2.5 Sediment
Backwash Filter
Backwash Flow Rate
One problem that may occur is if you do not have enough backwash ow rate to properly clean
the Sediment Backwash Filter.
You can verify the backwash ow rate by running the drain line into a bucket and timing it when
the 7500-REV2.5 is in Cycle 1 or backwash
