Greetings All! Please forgive this longer post.
I know this info is in my signature, but sometimes it won't show on the phone app:
I have a large AGP 18x33 that is buried with a 7ft deep end. I have a 250 lb sand filter with a 2-speed 1.5 hp pump. Things have been going well but yesterday I noticed a lot of debris floating. Having recently backwashed I thought that there is probably just a larger amount of leaves than normal, so I turned the pump on high and let it do it's thing. Last night, turned it back to low and things were going well. This morning, of course, floating leaves.
Usually I can just run it on low 24 hrs/day with no problem and it gets everything. So I think to myself, probably just needs to be backwashed. I turn the valve to backwash and turned the pump on high, but I noticed that the pressure gauge is at 4.
Normally on high the pressure is at 10, I will backwash when it hits 12-13 (Every 2 weeks or so).
Also the water coming out of the discharge hose is not gushing out as normal either.It's still coming out at a pretty good pace, (like a garden hose?) just not as high as normal. I let it run til it's clear, rinse, and then it back to filter as usual. (I do turn the pump off any time that I'm turning the multi-port)
So the pump is running on high and now the pressure gauge is at 0. On high it looks like it's only running on low if you look at the skimmer and return jet. Also, I'm seeing some tiny bubbles coming out of the return.
I did a quick search and the forum posts suggest that there may be a blockage in one of my lines, so I took the garden hose and ran it through, it doesn't seem as if there's anything in the line going from the pool to the filter. Also, I would think that if there were something clogging the return line the pressure would go up, not down?
I'm thinking I may have more than one problem, but who knows?
Can anyone help me figure this out?
Also, do you think it's safe to continue to run my pump on high, even with the lower flow? I just don't want to get an algae build-up on top of this.
