Creating a new post for myself because using the search function I found conflicting answers to these questions.
1 When replacing the skimmer face plate and gasket(s) what is the order of components.
2 when replacing the return (eyeball) face plate and gasket(s) what is the order of components.
3 when replacing the fiberglass steps trim and gasket (s) what is the order of components.
Currently my hayward skimmer is like this (non wide mouth)
Skimmer housing --- gasket (assumed)--- Metal wall --- foam --- gasket --- liner --- face plate --- water.
after reviewing the instructions on liner for a new hayward skimmer they do not require a gasket between the liner and the metal wall. But do require a gasket between the liner and face plate. they also don't make mention of foam. My thought is to try and cut back the foam and then reinstall like their instructions but maybe add an extra gasket between metal wall and liner.
Skimmer housing --- gasket (assumed)--- Metal wall --- gasket --- liner --- gasket --- face plate --- water.
On my returns i believe its just a face plate and liner, I have not tried to pull the liner off fitting yet. But I am thinking doing same thing sandwiching the liner with two gaskets
Return fitting --- gasket --- liner --- gasket --- face plate --- water
On the fiberglass stairs the trim is shaped like a shallow C and the stairs have grooves that receive the trim.
Fiberglass Stairs --- gasket --- liner --- trim
I am thinking that this is correct because the C on the trim and grooves on the stairls almost crimps the liner to the 1 gasket. 2 gaskets would probably be too thick.
Any problem with running a gasket on either side of the liner for the returns and skimmer, even though the manufacture does not specify it?
brief history on the pool
20x40 liner pool install in 1979. 2 returns 2 skimmers no main drain. I bought the house in Nov of 2014, pool was last used in summer of 2010. It had two years with a cover and two years without. last summer I was able to scoop all leaves and get pool blue and working again. halfway through the summer I noticed I was losing water (about 2 to 3 inches per week) and determined it was in the pool (not the pump or lines). uncovered the pool this spring and only have about 12inchs of water in the shallow end, so all signs point to the stairs gasket.
Noticed that the lower trim of the stairs gasket is not locked into the grooves like it should, my thought it 4 years of dormant it was able to stay sealed, but after a year of use that lower trim just worked its way loose and the gasket is no longer holding.
I hope to have some pictures for you this weekend.
thanks in advance.
