We are working on opening our above ground pool, we have a Hayward pump. Last year we were noticing sand in the pool repeatedly, so this year prior to opening we decided to take all sand out of the filter and check the laterals. We did that, all look fine, and put all back in, sand included. I then unscrewed the multi port top to check spider gasket, which appeared ok too. I screwed it back on, and we then proceeded to fill pool, hook everything up. Today I noticed large amounts of water coming from the top of the filter at the junction, and also water leaking into waste. No matter which position the lever in, the same. I noticed a couple screws not in all the way, so I tightened. It still seems to be leaking, though I plugged the return in the pool to slow it down. What could be going on here? I made sure the lis went on same way it came off, but did I need to lube or reseal something?? Thanks for any help! It’s ALWAYs Something. Ugh
