• What to Do if Your Tank is Not Level Out of the Box

  • Your black filter tank base is not glued to the bottom of your tank. Occasionally tank bases will become crooked during shipment.
  • If you find that your tank does not sit level on the floor, you can easily adjust it by holding the empty tank and rapping it on a concrete or solid foundation once or twice to level it.

How Your Sediment Backwash Filter Works

• Water enters the top of the tank and flows down through the media and up the distributor tube.
• The downflow type Turbidex Sediment Media Filter removes sediment and can be backwashed, which cleans and re-classifies the Turbidex Media, preventing channeling.
• During backwash the flow of water is reversed and water flows down the distributor tube and up through the media, lifting and expanding the Turbidex Media.
• During the backwash the Turbidex Media is cleaned by the action of the water flowing through 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 off the water to the house and you have an electric water heater, shut off the power to the water heater before beginning installation in case water heater is accidentally drained. Make the plumbing connections from your existing system to the bypass assembly, installing extra valves, unions, pressure gauges and hose bibs as needed.
3. Pick a suitable location for your filter system on a dry level spot where it won’t be exposed to freezing temperatures. A minimum of 20 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 Carbon 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 particularly if you have 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. Connect the External Flow Control fitting onto the Drain line. If you are going to be turning off the water to the house and you have an electric water heater, shut off the power to the water heater before beginning installation.
2. Make sure there is a working gate or ball valve before the system and also one after as well as a bypass valve.Get all of your plumbing parts together before beginning installation.
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 Carbon 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-REV4 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 fittings if needed.
7. Make sure bypass valves are closed (system is in bypass) when you first start installing and keep on bypass until you are ready to start it up with the first backwash.

How the Bypass Valve Works

• Turn knob so the valve is bypassed when installing.
• When you go to start up system turn the bypass SLOWLY to let water in and put in service.

Installation of Your System into Copper or Metal Piping Systems

• If your new filter system is to be installed in a metal (conductive) plumbing system, i.e. copper or galvanized steel pipe, the plastic components (bypass and connectors) 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 Carbon Filter Works

• Water enters the top of the tank and flows down through the media and up the distributor tube. The backwashing Carbon Filter removes Carbon and is automatically backwashed which cleans and re-classifies the carbon media.
• During backwash the flow of water is reversed and water flows down the distributor tube and up through the media, lifting and expanding the Carbon media.
• The 7500-Rev4 Control Valve is set to Filter Meter Type which means it counts or tracks the amount of water that is used and will backwash every 1400 gallons OR 7 days, whichever comes first.
• Because of the built in flow sensor feature, you can also see how much water has been used by reviewing the Usage Logs if you wish. See page 10.

Tank Assembly and Installation Instructions

1. Wrap the top of distributor tube with electrical or duct tape so that no gravel or Carbon media will go down the distributor tube when adding the media.

2. Add the filter gravel that came with your order. You want the gravel to cover the bottom distributor screen before adding the Carbon media.

3. Next add Carbon media. The tank should be about 2/3rds full of media, do not fill more than 2/3rds, even if there is some media left over.

4. Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube when removing cap or tape.

5. Fill tank completely with water. This will allow the Carbon Backwash Filter media to settle and reduce the need of purging the air out of the tank later. Allow Carbon to soak for at least 1 hour but 24 hours or more is OK. Carbon contains trapped air, and this will help remove trapped air.

6. Add a small amount of silicone grease to the inner O-ring, where the distribution tube goes.

7. Next, install the top screen by inserting upwards and rotating to lock in place. (This is a funnelshaped plastic screen that locks into the bottom side of control valve).

8. Lubricate the main tank O-ring only with silicone grease and screw on the 7500-Rev4 control valve carefully. Do not use pipe-joint compound, vegetable oil, Teflon tape, or Vaseline or other greases to lubricate tank threads.

9. Connect bypass assembly with 1” pipe connectors; install black clips and make sure valve is in the bypass position.

10. Insert meter cable into meter cable port on bypass.oil, Teflon tape, or Vaseline or other greases to lubricate tank threads.

11. Install inlet and outlet piping and hook up drain line.

12. If you are in earthquake zone, strap your backwash filter tank to wall with metal strapping.

13. Proceed to programming your 7500-Rev4 control valve

14. IMPORTANT: you must program the time and then start a backwash and rinse. The filter system must be backwashed and rinsed several times before using. See following pages for instructions.

Start the First Backwash

1. After programming, the system must be run through 2 or 3 backwash/rinse regeneration cycles to clean the new filter media.
2. Start with both bypass valves in the Bypass Position.
3. Press the BACK/REGEN button once to enter the backwashing cycle.
4. When the backwash icon is displayed, slowly open the bypass to a quarter position to make the water flow into the tank and out the backwash drain line to drain.
5. After several minutes open bypass valve completely. If possible, verify that the backwash flow corresponds with the size of your system below. You can easily run the drain hose to a bucket and verify the flow rate in gallons per minute. An adequate backwash is critical to properly clean the Carbon media. For example, if the backwash water fills a 5-gallon bucket in 1 minute, you have 5 gallons per minute (GPM).
6. 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 flowing meter on the left).
7. Repeat the Regeneration (backwash and rapid rinse cycle) step 2 to 3 more times until you see clear water through the drain line.

Congratulations, you are done setting up your valve!

Maintenance

• Every 4 to 6 years (in some cases it can last longer) remove control valve and empty the carbon filter media and replace with new media.
• There is no routine maintenance required for the control valve or filter media, other than making sure the system is set to backwash frequently enough to keep the filter media clean.
• Test the water before and after the carbon filter for a chlorine residual every 4 to 6 months. When you start to see a chlorine residual after the carbon, it is time to replace the carbon.
• Troubleshooting the 7500-REV4 Carbon Backwash Filter

Backwash Flow Rate

• One problem that may occur is if you do not have enough backwash flow rate to properly clean the Carbon Backwash Filter.
• You can verify the backwash flow rate by running the drain line into a bucket and timing it when the 7500-REV4 is in Cycle 1 or backwash.
