Does anybody here know the name for a plumbing style where the main drain is plumbed into the skimmer with a diverter valve? I remember seeing a post here previously somewhere where it was mentioned as the "X Style", but I can't seem to find it now. Does anybody here know what "X" is? Thanks!

Bought this last week: US Pools Tool Organizer This is a fantastic storage rack from US Pools for all pool cleaning accessories. I had this stuff laying all around my pool area for years before I finally got frustrated not being able to find things when I needed them (tossed loose into a...

I have a mesh cover so I almost always have to SLAM when I open... Second day of SLAM, the water is clear enough to see the debris on the bottom, so I proceed to vacuum to waste. I get my filter online and start filtering. After about 24 hours, the pressure climbs by about 6psi so it's time to...

Who here is brewing this season? What are you making?

Last season I hired a local pool company to close my pool for me because I don't have a blower (and because putting the cover on can be a PITA ) Anyway ... I valve in my filter for the first time and the air bleed won't stop leaking water. Long story short, these jokers removed the little O-Ring...

Due to my zipcode being very hard hit with COVID-19, 12% liquid chlorinator has been hard to come by temporarily. After opening, I saw that both my CYA and CH are below where I like them, so I ordered some granular trichlor and cal-hypo online and I am experimenting with alternating them (being...

I just had rain and was trying to get the main drain to suck up some dirt from brushing, and even with float valve diverter closed I was still not getting full suction. I just figured out a trick to do this. All you need to do is hold the Weir door closed until the skimmer drains. The float...

Does anybody know the correct part number for the pentair / swimquip U3 /8650 Skimmer float valve o-ring? I have tried several that claim to fit, and the width is correct but they all seem to be about 1/4 - 1/2 inch too big in circumferance, including the one that came with the pentair...

My coupon wizard wife got 2 bottles of vitamin C tablets for free, one with zinc and one without. I put the non-zinc tablets into a tube sock, hit it with a hammer a few times and put it on some stained areas at the bottom of our pool. The results were amazing! My question is, is it ok to also...

Turns out, I had initially WAY overestimated the size of my inherited pool at 15k gallons, and was consistently overshooting when adding chemicals. I became suspicious when a carefully measured dose of Muriatic acid caused a much larger pH drop than expected. By doing careful measurement and...

I had a question about the FAS - DPD test. I like to use it to spot check my chlorine levels but want to save on expensive reagent. If I want to do a test with 1 drop reagent = 1ppm Cl, should I be using a 5ml sample or should I be using 5ml pool water diluted with 5ml distilled H2O? I am only...

Just wanted to take the opportunity to thank you guys for providing this resource! I started out knowing nothing about pools but I found this site 2 years ago and now my pool is crystal clear and balanced. :handshake:
