Hi all, this is my first post! I’ve had my pool for 10 years and this year my problems started with cloudy water. I noticed that when vacuuming fine silt, it re-appeared in my pool from the return lines. I’ve done a number of things but now I’m getting sand in my pool. Here’s what I’ve done: replaced the sand, inspected the laterals/standpipe, replaced the multi-port head on the sand filter, replaced the sand again (I thought it might be the wrong sand) and re-inspected the laterals again. I’m also getting fine pine needles going right through the filter back into the pool. I’m pulling my hair out right now…don’t know what more I can do! The only other thing I’ve noticed is that where the multiport fits into the stand-pipe, it’s not a snug fit. Is it possible that this is where the problem is? HELP!
