Cpvc is fine for direct hook up on water heaters.

Not in my world it's not...

Be real careful with any chemicals around CPVC. Manufacturers have a full list of the chemicals to stay away from including WD-40.

I had a condo project where the plumbers used Acousto-Plumb isolators on FlowGuard Gold which seemed like a great idea but it was a major blunder. The chemicals in the Acousto-Plumb changed the CPVC into a balloon like material that popped and would flood units.

I was being sarcastic bud. And no, cpvc is not OK to hook direclty up to water heaters if they are gas. Go read your flowguard installation manual.

I was following matt's sarcasm about transitioning to cpvc for heaters and boilers. I guess no one caught that.

I'm the guy who showed everyone the article about environmental stress cracking in the thread "Not a way to start the new year" remember?

What, like this (see picture)?

That was from WD-40.

The isolators you are talking about contain a plasticizer that softens the cpvc when it leaches into the resin. When it softens, it balloons up because it is too soft to resist the internal water pressure anymore.

I can't understand why anyone would want to use CPVC pipe on a large scale with all that list of products that are chemically incompatible with it. It just seems like a disaster waiting to happen.

I was surprised to see IPS White Seal is not compatible with CPVC. The can I am holding in my hand says "White Seal may be used for threaded connections on all metals, ABS, PVC, CPVC, including FlowGuard Gold, BlazeMaster, Corzan, and Polypropylene and Nylon plastics." I'm glad I don't deal with much CPVC out here.

What was so aggravating to me is that both the FlowGuard and the Acousto-Plumb literature says they are not compatible with each other and still the plumber used them.
