Chlorine in water

BDR529

Noticed with all the added chlorine in the water it is distorting the toilet flush valves keeping them from fully seating.

Bigger concern is what it might be doing to domestic pex. Any Thoughts?

Thanks for the info. So they don't know either just.. "Frequent or continuous exposure to water conditions beyond those used in ASTM Test Method F2023"

Hi, Maybe off topic a bit, but I've found that the red rubber flappers hold up better to chlorine and chloramine than the black rubber flappers.

What about the blue ones?

Hi @ChrisJ , I don't have experience with those, so hopefully someone else does 😇

Years ago the red rubber flappers were supposed to have been introduced as more of a chlorine-resistant flapper. The blue flappers? I haven't read or heard a thing about how well they hold up with chlorinated water.

The OEM Gerber I'm using right now has lasted several times longer than the red adjustable Fluidmaster ones I used for years in the same toilet. They're like a translucent clear color.

I think the OEM Kohler flapper I had was blue.

The plastic valves in the toto's look like there are melting

When my local water department switched to using chloramine from just plain chlorine as a disinfectant, that’s when the problems started. I think it’s the ammonia component that is more aggressive than the chlorine.

Article is from a cpvc manufacturer.

The poly B failures were less likely on the piping as the bad fittings. (acetal fittings and Aluminum crimp rings.)

Bad water (yes high Chlorine is bad water) will damage any piping long term.
