This pool is so frustrating I'm tempted to make a volleyball court out of it by filling it with sand.
It originally had a sand filter but had never worked properly (the barracuda would never get out of the deep end)
I replaced the sand filter with a hayward c800 cartridge filter and a new hayward 1.5 h/p pump pump a couple years ago (thought bigger was better) also replaced the barracuda with a different brand pool cleaner (cant remember brand). Pretty much the same results with the cleaner, it gets to the transition from the deep/shallow end and just cant seem to get up the incline and then just pretty much stays in the deep end.
I have cleaned the filters and even replaced filters with OEM hayward filters.
Additionally, when i first clean the filter and start the pump the circulation is very strong but dies out within a hour or so to a slow dribble with minimal debris in the filter. If i leave the filter out of the canister the circulation stays strong throughout but I obviously have no filtration.
Fast forward to present day, the 1.5 h/p pump died my local pool store said the 1.5 h/p was causing the problem since it produced too much gpm for the c800 filter. I bought a 3/4 h/p pump on their recommendation but I still get the loss of strong circulation after a short time.
They say they will come out & look at it for a charge of course (Im sure they will recommend a new bigger filter) if that doesnt solve the problem they have already told me they would have to charge me to come back out and further diagnose the problem.
I'm not in a position to just change out parts till they come up with a solution & be charged every time they come out.
I have no problem changing the filter size but dont want to if that's not the problem. Any suggestions on correct filter size or other thoughts etc would be appreciated.
the pool is approx 13000 gallons if my math is right.
