Maybe you guys have a suggestion to try because I dont know what else to try. I keep getting sand in my pool. I have kids and I'm sure some of it is them. I think the problem goes beyond that. I have already replumbed the filter, bought a new multiport valve, changed the sand and lateral assembly in the Hayward S244T filter. Not sure what else I can do?? I just got a new liner installed so I thought that would help too because the old one was coming off the wall.
