    Housing gasket leak!

    Update: My housing gasket started leaking again, so I ordered the round profile O-ring, instead of the square. Presto! Works like magic, no more leaks. So if you've got the Pac Fab Challenger pump, and it's leaking, make sure you get the round O-ring. It comes in the go-kit. If you order the...

    Housing gasket leak!

    I do have an air release valve on top of the filter, but if that was allowing air in when the pump is off, wouldn't it be squirting water out under pressure?

    Housing gasket leak!

    Yes, it is Part #14 on the schematic. If there was a recall or technical service bulletin, as they say in the automotive industry, I'd like to know about it. I'd order that new round O-ring in a minute if I thought it would fit in the square groove.

    Housing gasket leak!

    Mating surfaces seem smooth. O-ring not pinched. The band clamp is unfortunately in a tight place. I've used a rubber mallet and lightly tapped around it as I tighten, but I can't reach all sections of it. Here's an update though: The gasket (square vs. round) fits very nicely into a square...

    Housing gasket leak!

    Every morning when my pool pump starts running, it has to pump large volumes of air out of the system before water emerges from the jets. There has been a leak under the pump for some time. (It's a Pac Fab Challenger 1hp.) I changed the housing gasket - still leaked so I changed the pump shaft...

    pH rise in spa that was just drained & refilled

    Holy Crud! Everything dropped today. I think it may be because I used a different bottle of acid. I'll bet that other bottle, which I finished yesterday, had gone bad or lost strength. My pH is now down below 6.8, and TA is down to 10. Now we're getting somewhere!

    pH rise in spa that was just drained & refilled

    Checked this morning... TA has finally dropped from 100 to 70, and calcium hardness from 220 to 180, no change yet in pH. Added another 22oz. of acid and will check again this aft.

    pH rise in spa that was just drained & refilled

    So technically we're a public pool. It belongs to our condo association, so condo owners and their guests/renters are authorized to use it. We'll go for days or a week at a time with no one in it at all. It's busiest may see 6-8 people per day. I don't know whether it's "legal" or not - it's...

    pH rise in spa that was just drained & refilled

    It's a fiberglass tub. The surface is smooth and not rough with scale. There is no hydrogen peroxide in the tub as I just drained it. Nothing but tap water, which was 7.5 when it went in yesterday and jumped to 8.2+ overnight with nothing but the heater and the jets. The spa is outdoors though...

    pH rise in spa that was just drained & refilled

    New here and this is my first post. In fact I'm new to the whole pool/spa maintenance thing, but I just completed the CPO class. I have a 1,000 gallon hot tub, which is using hydrogen peroxide and U/V light to sanitize. I cannot get the pH to come down and stay down at a reasonable level. In...
