Last year i started to notice 2 things - a small leak out of the MPV waste port of my Hayward de filter while in filter mode and a sense that i had a constant presence of "silt" at the bottom of the pool. This year I replaced the spider gasket, the old one looked fine but did it anyway. well these 2 conditions still persist. Any suggestions on how to address/confirm these items? As some back up history, I read somewhere that the gaskets should be glued in some way, the original was not that I could tell. I did lube it top and bottom before putting it in. Also, after I vac the pool, today being the most recent to finally got it clean after the spring opening, within a hour I noticed the "silt" on the side wall of the deep end right under the return nozzle. Are the 2 issues I am experiencing related? In the meantime, just like last year, I plugged the waste port to keep the water from constantly dripping onto my pool pump motor. Any insight is greatly appreciated.
