Hi all. I have a Pentair (actually a Purex Triton) filter that has a hairline crack in the lid. Given it’s more than likely 22 years old, I’m thinking about replacing the whole filter housing vs just the lid. Not sure how much life is left in it anyway, it’s got that “old fiberglass” look to...

I've read a bunch of threads on here about the Pentair lights leaking - mine is the old incandescent type with the retaining ring clamp. I have 2 in my pool, and both are leaking to varying degrees. I figured out that one of them was leaking at the cord, so I sealed them both with a-b putty...

Just wanting to understand why TFP recommends a CH level that is quite a bit higher than what I've seen elsewhere. My pool warranty sheet, for example, gives a range of 200-400, while Poolmath is saying 250-650, with 350-550 being ideal. Mine is at 300. I'm inclined to stay there unless there...

The last few days I've been adding a small amount of acid every day. I get pH to 7.6, by next morning it's back up to 7.9. TA was 70 yesterday - we got a ton of rain a few days ago, and plaster is new. I expected to be chasing pH with new plaster for a while, but didn't expect every day...

Had pavers cleaned and sealed on Friday. They used a sprayer to apply, and even though they did what they could to keep it out, some did drift in. The water was pretty hazy the next day, but cleared some. Now 3 days later it still looks weird to me, like it has an oil slick on top. The sealer...

Couple questions, actually. I have 3 way jandy valves to go from pool mode from spa mode. Spa is draining slightly at night into pool. If I have the valve set just right I can keep it from draining, mostly. There is no check valve. 1. Is the 3 way valve supposed to be completely watertight...

Very new here. Just had my pool redone so I'm making a commitment to mostly doing all the treatment myself. The pool builder has been doing everything up until today, and I've been relying on the pool store to do my water testing in the past, and I'm in the process of ordering test equipment...

In the midst of a pool refinishing startup. Lots of things have changed since there are new drain covers, jets, etc. I’m getting air in the system periodically that I can generally solve by lubing the pump filter cover o-ring. Since I’ve been messing with it more over the last few days and...

Hi all - I’m a pretty new pool owner. We bought our house 3 years ago and I’ve been looking after it myself since the beginning. We just had it redone and it looks beautiful, but of course now I want to keep it as good as possible, so here I am! Attached photos of before and after.
