The valve seat gasket inside of the valve may have become worn or loose. If this is the case, you will need to replace the gasket. With the pump off, remove the cover screws of the valve. Note: Mark the top and bottom of the valve with a marking pen. It's very important that you do not change the location of the cover when re-assembling. Some newer valves will have a flat spot along side one of the cover screws. When re-assembling, align the flat spots. Gently remove the old gasket and glue, ensuring the channels are clean and clear. Use 3M adhesive, part number SPX0710Z9, or crazy glue**. Lay a bead of adhesive into the channel where the gasket sits. Place the flat side of the gasket into the channel. Apply pressure to firmly seat the gasket and let dry for 24 hours or contact your Authorized Hayward Dealer for repair./li> **Crazy glue: Use caution when using crazy glue. You will have only one chance to seat the gasket. Why does my filter run at a high filter pressure and has reduced water flow to the pool? A dirty filter maybe the problem. When the filter pressure rises 8-10 PSI over the clean starting pressure, it is time to backwash or clean the filter. If there is algae in the pool, it maybe clogging the filter, keeping the pressure high. The filter cannot kill algae. Contact your Authorized Hayward Dealer for proper chemical applications. If the filter pressure continues to run high with reduced water flow to the pool, the pump may be moving more water than the filter is designed to handle. Check the flow ratings of both the pump and filter to ensure they are sized correctly. You may have a blocked or plugged return line. Contact your local Hayward dealer for service. DE Filters The Diatomaceous Earth (DE) filter contains filter elements that are either curved grids or Flex tubes (long finger-like tubes). They are covered in a fabric on which the DE forms a coating. The DE acts as a filter by permitting water to filter through the DE and leave the impurities behind. The DE filter has the ability to filter out microscopic particles. Why does my filter pressure rise very quickly, even after backwashing? D.E. filters filter the water down to 1-3 microns, every time the water passes through the filter. Maintain a balanced clear pool and this will reduce incidents of rapid pressure rise. One possibility is that the filter grids or Flex tubes are clogged with minerals or oils. You should clean your grids once a year, or season, with a degreaser and if needed an acid bath. Minerals and oils embed themselves in the fabric of the filter and reduce the available surface area used for filtering. If too little DE is added during pre-coat, debris and particles will embed in the fabric. Cleaning with a high-pressure hose, NOTE A POWER WASHER may be needed to remove the grids. If cleaning does not work, then replacement is the only option. Will backwashing thoroughly clean my DE filter? When a DE filter is properly backwashed you will be removing about 80-90% of the DE. Remaining DE may be clumped in the corners of the filter or caked in the middle. This is common. After backwashing, new DE must be added to the filter. Add the entire amount of DE the filter recommends. If you see DE returning to the pool, vacuum it to waste, after it settles. The next time you backwash and recoat, decrease the amount by 1 pound. This will avoid DE going back into the pool. The only way to remove the entire DE is to disassemble the filter. The next time the filter is disassembled and cleaned, pre-coat with the entire quantity of DE. Remember, the filter should be taken apart and cleaned at least once a year. How do I add DE and how often do I need to change my DE? DE is added through the skimmer with the pump running. Each filter has a different requirement of DE. At initial start up or after a thorough cleaning, the filter will need to be pre-coated with DE. The filter label will state the amount of DE required. Start the pump and once the pump is fully primed, measure the DE using a DE scoop, part # EC10SC. Slowly add the DE into the skimmer. The pump will draw in the DE and send it into the filter, where it coats the grids or Flex tubes. Once all the DE is added, take a reading of the filter’s pressure gauge. This is the clean starting pressure of the filter. When the pressure rises 8-10 PSI above the starting pressure, it is time to backwash or clean the filter. After the filter is backwashed or thoroughly cleaned, by taking it apart and hosing it out, you will need to pre-coat the filter again with the entire amount of DE stated on the filter label. Why is DE leaking into the pool? There are only a handful of reasons DE is leaking into the pool. They vary depending on which DE filter you have. Vertical Grid:
(1) Too much DE was added
(2) Tear in the fabric of the grid
(3) Crack in the top manifold
(4) Bad o-ring on the standpipe (the pipe the DE cluster sits on) Perflex "Bump" Filter:
(1) Too much DE
(2)Tear in the fabric of the fingers
(3) Bad diaphragm gasket
(4) Cracked tube sheet(s)
(5) Loose or missing tube sheet bolts
(6)Bad o-rings on the bump shaft How do I backwash my DE filter? Vertical Grid:
When the filter pressure rises 8-10 PSI over the clean starting pressure, the filter must be backwashed. Turn off the pool pump. Rotate the multiport valve to backwash position or slide the slide valve up. When the pump is turned on, the dirty DE and water will flow out to waste. Once the water runs clear, turn off the pump. With a slide valve, push the handle down and start the pump. Once the pump is primed, add the required DE. If using a multiport valve, rotate the handle to rinse. Turn on the pump and let water flow for 20-30 seconds, cleaning out the plumbing lines. Turn off the pump and rotate the valve back to filter. Turn on the pump and once primed add required DE. Perflex "Bump":
Perflex filters are unique because they cannot be backwashed. Once the filter pressure rises 8-10 PSI over clean starting pressure, it is time to bump the filter to regenerate the DE. Turn the pump off and grasp the bump handle. Slowly raise the handle then firmly push it down. Repeat this action 3- 4 times. Inside the filter the Flex tubes are being raised and lowered, shaking the DE and debris off the tubes. The DE is then sitting on the bottom of the filter.
When the pump is turned on, DE will recoat the tubes. The filter pressure will not drop to the original starting pressure, but will drop lower then the previous reading. (Example: the original starting pressure was 10 PSI. You "bumped" the handle when the pressure reached 20 PSI. After the bumping, the pressure dropped to 13 PSI.) The pressure reading after bumping is the new starting pressure. When the pressure goes 8-10 PSI over this, the filter will need to be bumped again.
When there is no pressure drop after bumping or the pressure rises very quickly after bumping, the DE will need to be drained and replaced.
To replace DE turn off the pump, bump the handle to shake DE off of the tubes and open the drain valve. The pump can be turned on to help expel the dirty DE, but it should be for no longer than a minute. A jet-action cleaning wand can be used to remove any remaining DE.

Once a year, the filter should be taken apart and thoroughly cleaned. Note: Take a reading of this new clean starting pressure, so you have a reference point for the next backwash cycle. Water may need to be added to the pool to replace the backwashed water. Sand Filters The sand filter tank is round or egg shaped. The sand contained in the filter strains the impurities from the water as the water passes through the sand. The sand filter uses a multiport valve to direct the water through the filter or out to backwash. The valves are either top or side mount. Both valves work the same way. In filter position, the water is directed over the top of the sand bed and, as the water flows down through the sand, the sharp edges of the sand catch the particles in the water. The clean water is pushed out of the filter through the bottom lateral assembly. The laterals are in the shape of a wagon wheel, with tiny holes along the top edge, to allow the clean water back to the pool and the sand and dirt to stay in the filter. Why is the filter continuing to run at high pressure even after backwashing? Make sure you are following the instructions in your Hayward owner’s manual. The sand bed may be clogged with mineral deposits or other material that will not backwash away. Some calcium based chlorines and other alternative sanitizers could cause a build-up in your sand bed. You may need to change the sand. Before you change the sand in you filter, try removing approximately 1” of the top layer of sand, and replace with the exact amount of sand removed. This sometimes rids the sand bed of the deposits clogging the filter. You may have to clean you filter system with a special filter cleaner, check with your Authorized Hayward dealer for proper procedures. Check to see if there is a closed or partially closed valve on the return piping. Your pump may be too small to provide sufficient flow for proper backwashing. Your filter will filter properly, but if your pump does not supply at least 60% of the filter’s designed flow rate, you filter will never backwash completely. Refer to the label on you filter for flow rate requirements. It may be necessary to upgrade the pump or downgrade the filter. Your pump may also be exceeding the maximum allowed flow rate of you filter causing excessive backpressure. Check you Hayward filter owners guide or the operations label on you filter for the maximum allowed flow rate. You may have to downsize the impeller or pump to a lower horsepower or change the filter for one that will accommodate the pump’s flow rate. If allowed to continue, a pump that exceeds the recommended flow rate of a sand filter could cause the sand bed to channel (small channels in the sand that allow debris to pass unfiltered). This would cause debris to by-pass the filter.
