How to change sand in a s244s sand filter
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
