    Brass Air Relief Valve for Pentair CCP420

    Can anyone recommend a brass manual air relief valve for a Pentair CCP cartridge filter? My filter sits in the AZ sun and the plastic ones just don't last. John

    Water Evaporation Volume - Phoenix

    Has anyone in the Phoenix area accurately calculated their pool’s water loss due to evaporation over the course of a year? I was thinking that a flow meter on the autofill line would be nice.

    Water Softener for Pool?

    Does anyone make a water softener specifically for a pool? A unit that can be placed outside in direct sunlight by the other pool equipment. If I can soften the water supply that feeds my autofill, I can eliminate one headache….CH too high. My municipal water supply is 240 ppm. My pool is in AZ...

    Should I Lower TA Slightly

    There’s not really anything else I can manage except TA and PH. Fill water TA is 120, fill water CH is 240, and fill water PH is 7.7. Test kit is Taylor K-2006. As stated above, I have to manage CL with stabilized chlorine most of the time. When I’m in town, I use liquid. Hence the low CYA for...

    Should I Lower TA Slightly

    I have a 10K gallon pool in AZ. I use a combination of bleach, trichlor, and dichlor to manage the CL. I can’t solely use liquid chlorine because I am not there on a day to day basis. Here are my numbers from this morning: FC=3 CYA<30 PH=7.6 TA=90 CH=240 I want to keep my PH in the 7.4-7.6...

    Fast way to dissolve CYA Conditioner ?

    I'll be draining my pool next week for tile cleaning and also due to "off the chart CYA". I'll have a few days to kill before I get started and was wondering if I could start the CYA dissolving process in a 5 gallon bucket 3-4 days before I'll be refilling the pool? Has anyone tried this with...

    Valve Identification Help

    I don't have a picture of the bottom, but the actuator handle does say Pentair. I think it's safe to say it's a 2" Pentair. I'm pretty new at this...LOL. I'll likely order 2 shaft O rings, 1 spacer, and a cover O ring. Is there a preferred place to purchase these online?

    Valve Identification Help

    Can someone please help me identify this valve? It has a shaft leak and I'm assuming I need to replace the shaft seals. I think it's a Pentair, but really not sure at all.

    What am I Missing? CYA and FC

    I've read volumes about the relationship between CYA and FC. However, I must be missing something. If FC is what actually sanitizes the water, and the actual FC level is, let's say 3ppm, why isn't that enough FC even if the CYA is extremely high at say, 300 ppm? Isn't there still 3ppm FC that is...
