Your pool filter valve is one of the most essential elements to your pool operating correctly. Problems caused by a filter valve dysfunction include water that leaks out of the backwash line, dirt going back into the pool when vacuuming, and the pool water never becomes clear. These are all indications that your pool filter valve needs to be replaced. With the proper tools and instruction, you will be able to replace the valve on your own. Follow these steps to get your pool running properly.

Step 1 - Take a Picture

Replacing your pool filter valve on your own will require the dis-assembly and reassembly of the valve housing. There will be a lot of parts that you will have to touch. Taking a picture of the valve before you disassemble will prevent any issues when the valve is reassembled. It is also a good idea to write down your steps if you do not have a camera.

Step 2 - Disassemble Valve Housing

Before you begin dis-assembly, be sure that you turn off the pump. Depending upon your valve's manufacturer, there are six to eight screw and bolt combinations that secure the top of the valve housing. Place your screwdriver into the screw and with your adjustable wrench, loosen and remove the bolts from the screws. After all screws and bolts are undone, remove the top. A dome-like piece is attached to the top. This is the key stem which controls the flow of water in and out of the filter housing.

Step 3 - Locate Spoke Valve

Look down into the valve housing and locate a spoke-like device. This is the valve filter. In most valve housing, this filter is glued into the grooves of the valve housing. You may discover that the spoke valve has come unseated from the grooves of the housing or it may be ripped or torn.

Step 4 - Remove Spoke Valve

With your pocket knife, scrape the spoke valve from the grooves of the housing. Scrape firmly but not hard enough to damage the grooves for the valve. After you have removed all traces of the spoke valve, lay the valve assembly to the side and allow it to dry completely.

Step 6 - Prepare And Place New Valve

Prepare the replacement filter by turning it upside down and adding a light coat of the PVC glue to the whole underside of the valve. It is important that you use a light coating of glue so as not to seep from under the valve once it is seated. Once the glue is in place, place the valve back onto the grooves of the valve housing and ensure it is properly seated. Allow the glue to completely dry.

Step 7 - Reassemble Valve Housing

After the glue is dried, you may now reassemble the valve housing. Before seating the key stem assembly, ensure that the O ring is in good repair. Install the valve housing back to its place and turn on the pump.
