Hi - first time poster, long time lurker. Great site
I have a 16x32 IG vinyl pool. Hayward 48 DE microclear (DE) filter. 1 skimmer, 1 return and two 'jets' by the steps/bench at the far end of the pool. on the edge of the pool by the step is a twist cap that used to adjust the amount of air into the two return jets, creating sort of a jacuzzi type effect by the seat/stairs.
Pool company opened the pool last weekend and it's been running well. only problem is now when I open that twist cap by the stairs, it just overflows w/water. Also the pressure of the jets seems less than it should be.
Any thoughts on what went wrong? Should i just remove the adjusters and try larger ones? Clogged pipes? wrong jets installed? Any harm in replacing them w/different types?
