Hello everyone, noob issue here. I've inherited an above ground 15x30 oval pool that i'm trying to put under my control. I think I understand where I need to take things chemically, but right now I seem to be having a mechanical problem...
I have a Jacuzzi 190L sand filter (no idea on the age of the sand), and a 1HP pump. The pump filter basket has a drip around the big O ring when things aren't running, but its not serious enough to be causing anything anywhere near what i'm seeing.
All of a sudden in the last week whenever I shut down the filter/pump (after running it for say 12+ hours), I seem to get about a 1.5 foot geyser out of the skimmer for a few brief seconds.
I'm not sure if its related or not, but the only thing I can think of doing before this was just trying to use one of those suction brushes that attaches to a pole to clean up the bottom of the pool after we were out of town for a few days.
The return pressure in the pool seems to feel about the same as it did before this started happening (scientifically measured by placing my hand a few inches from the return outlet and feeling how much resistance i have to put up to keep it at that spot).
I noticed that after after cleaning up the pool bottom with that suction brush that day, turning the pump off (for whatever reason i don't remember at the moment, probably backwash/rinse), and then turning it back on caused the return water to appear to be shooting back all that stuff i cleaned off the bottom of the pool (discolored water).
The pressure gauge on the filter seems to be busted, so I ordered a replacement. but not sure what else to try.
I've tried cycling the filter through the various modes of filtering/rinsing/backwashing/draining/whirlpooling in hopes that something would kick over, but alas, i am here seeking guidance
i'm leary of running the filter/pump further, worrying that i might be damaging something.
I understand this is a pressure issue, but not sure what its stemmign from. could it be that the sand filter hasn't been changed in forever and a half and just finally got too clogged up after my most recent cleaning?
TIA for any gems you may bestow upon me.
