Question about Hayward SAND FILTER, PRO SERIES
It is simple and take about 1 1/2 hours . Turn off system off and close valve on the top to closed position. Remove clamp at the bottom of the valve that holds the tank and valve together. Remove the Valve by lifting
up the valve off the sand tank. You will need a device called a "Sand Changer" which is a device that syphons out the sand via a water hose and a discharge hose. This device is a life saver. Duck tape a 1 1/2" pvc pipe the length of about the height of the tank plus 6" so you can press the sand changer with the hose wide open down into the sand. "do not empty water in the filter as this aids in the syphoning process. then connect the hose provided in the sand change box to the sand changer device. this will be the discharge hose. You are ready to start the syphoning process. It may take a minute to get the syphon but it will syphon depending on the condition of the sand.after discharging most of the sand you will need to remove the the center pipe that has a hub with Latterals at the bottom. the latterals typically unscrew for the hub. These tubes act as the Pressure burst that cleans The sand when in Backwash mode. Remove the latterals by un screwing them from the hub. Once tank is clean reintroduce the hub pipe and latterals into the tank. Ad proper amounts of sand. The amout of media can be found on the side of tank on the sticker. consult owners manuel or if you have the make and model consult manufacturer. once proper amount of sand is back in tank. Typically sand tanks or 300# media or 600# media. Ps when introducing sand into tank cover open pipe at the top of the hub so sand does not enter pipe or sand will return to pool. fill with water and reassemble valve. and Backwash sand till dust in the eye glass is clear. then Rinse. Return to filer and your done.

Unhook the plumbing from the multiport valve, hopefully you have unions, it would make it easier. Take off the multiport valve on top by removing the bracket, usually held on by two phillips held screws that go into corresponding nuts. After bracket is removed, carefully wiggle the valve straight up, Don't wiggle it side to side, the PVC shaft in the is like Schedule 20 and breaks really easily. After valve is off do not try and pull the shaft up, there is too much sand waying it down and you will break it. Remove the sand with a cup or pop bottle cut in half or whatever. It is a pain to keep scooping it out with the shaft in your way, but I emphasize the strongly, do not try to move the shaft out of you way or pull it out without getting enough sand out of there. The other way to get the sand out, a little easier, is use a shop vac. You have to do it slow and kinda jiggle the hose while sucking sand because it'll clog the hose up. Get all the sand out, pull the shaft and lateral assembly out. The newer laterals fold up kinda like an umbrella so you can remove it, the older ones you have to unscrew each later individually to remove it. Inspect the shaft and laterals thoroughly to make sure none of them are cracked or not seating properly. Spray everything off, reinstall the lateral assembly, center it in the filter as best you can, most of them don't lock into anything, they just kinda sit there. Put duck tape or something over the top of the shaft so no sand gets in it. Pour about 50lbs. of sand in, (usually 1 bag), and recheck the shaft to make sure it is centered. An S244 requires 300 lbs. but just double check the label on your filter. Pour it all in, take the duct tape off of the top of the shaft, slide the valve back on, lubricate the gasket on it first, retighten the valve via the bracket you took off. Hook the plumbing back up and you are good to go. Backwash it right off the bat for a couple minutes before putting it on filter. You can potentially blow dust into the pool if you don't

This indicates that one or more of the laterals are cracked or broken. You will need to open the tank, remove all the sand, inspect the laterals(tubes that come off the center 'stand pipe'). replace any that have cracks or are broken. If you can't tell, replace them all. Fill tank back up with the right amount of sand and close it all back up.

SOURCE: model # s244s has dirty
This is a serious issue. These vessels are only pressure rated to 50 PSI. Anything more can be an explosion hazard.SHUT DOWN THIS SYSTEM!
You need to remove all the sand and replace it. While your inside, you must clean the LATERALs. (small tubes on bottom of the filter)
This will reduce the pressure.
It is a good idea to replace the laterals in the bottom of this filter if it is in your budget to do so. The pvc laterals become brittle and often break when tampered with .
Note: only use #20 silica pool filter sand as a replacement.
