Ph 7.7 Cl 2.0 TA 75 Cya 70 Ch 500 Salt 3600

SWG IntelliChlor-40

My salt water pool has five Pentair check valves and one Jandy check valve. The pool is 14 years old. The Jandy valve has never been replaced and looks and works fine. The Pentair valve flappers only seem to last about three years. And cost like $75 - $130 each, and I need five each time...

I happened to look at the brown boxed $19.98/2 gallon acid at Home Depot today. It was labeled 31% (Typical of pool store MA). Vs the old white boxed $16.98/2 gallon labeled 15%.

I have four actuator valves and four Pentair check valves in my system. I recently disassembled them for the first time since buying house. I think they are 12 or so years old. I found that every actuator had at least one stripped screw and same with check valves. One check valve, the screw...

I live in Southern CA. Not much rain. Just lots of evaporation and adding. I have a separate water meter for the pool and add about a pool's worth of water a year. The tap water here is quite high in CH, up to 400ppm. It's not hard to see why in five years, my CH was out of control bad. I...

A couple years ago, my Pentair Whisperflow VS 3050 locked up. Turned out the motor was "sagging". On further inspection, under the pristine paint, the aluminum(?) casting/flange between the motor and fiberglass pump backplate had dissolved into white dust to the point that the motor flanges were...

I have one, but I'm a worry wart engineer who thinks the the pump bearing will go bad or a pipe will break or something tragic...

We once had a neighbor we had never even met call us and pretty much tell us she was coming over with her kids. My wife firmly said no and the woman said, "but it's so hot". My wife said, "then you should build a pool". I'm afraid to have anyone house sit because I'm afraid they'll have a pool...

Thanks for fixing my URLs and the quick expert analysis. I'm surprised that the references use ethylene glycol (which I thought was poisonous) considering I think their work is intended for reservoirs etc. Maybe that's why the one msds references propolyene glycol? And thanks for reminding us...

Anyone using the newer Natural Chemistry Cover Free? I found the ingredients (stearyl alcohol, propylene glycol) here: https://media.nat.cm/filer_public/3a/c4 ... _aug14.pdf I also found a fascinating, though over my head patent here: http://patentscope.wipo.int/search/en/d ... escription...

Has anyone tried extending the life of a solar cover by using something like 303 "aerospace protectant" (high tech armour all)? Any other thoughts?

If I use a softener for top off, is the added/accumulated salt you guys are talking about from poor rinsing of the resin after regen? I would have thought sodium buildup would be a problem as that is what is exchanged with the calcium. Or does the sodium combine with your chlorine and make...

Topic split from 3 year old thread to create new thread. Please start a new topic when asking a question. Bama I have a salt system. Salt test says 4000PPM. CH 1100PPM (Southern, CA. fill water is really high - just keep adding more CH) How does trading high CH cause high salt? Were they...

If topping off with softened water, is there any concern that the sodium (from the ion exchange) will build up? I have a salt pool and I'm still baffled as to what happens after the sodium/chlorine get split by the cell (do they recombine back to na/cl?) Will all that extra NA eventually cause...

I have a one year old SW pool w/ Pentait ECG. I'm getting flakes at the returns. It doesn't tast like salt (Leslies dude told me that's what it was) CL, PH, CY are good. Last month I cleaned the filter carts and inspected the cell. nothing in it. put in some mild acid/water. no bubbles. I...
