When we install pex here we have to hydrostatic test to 200 psi but this voids manufactor warranty. Anyway around this?

No. But you need to let every manufacturer of PEX know about this.

See if they will fight your battle.

Have you made the local inspectors aware of this?

I've shown them the literature from zurn and they don't relent.

Then make them sign a liability form that makes them responsible for system failures before pumping the system up.

They approve a material then make you use it in a way for which is wasn't designed and void the warranty. I'm not attorney but they may well be liable.

Perhaps, but if you document it there is no grey area.

Not only that, but if they refuse to sign then GJ has a basis for refusing to compromise the integrity of the product, it puts the ball in their court to prove it doesn't void the warranty.

What is Hydronic testing? If it is an air test to ensure no leaks the code I believe it states "Working Pressure" for the test.

Hydrostatic. Flood the system and use a hydrostatic pump to pump it up to 200psi. Its code down here for all potable water systems inside the walls to be tested at 200 psi. Not working pressure at least for here. I have pumped PEX up to 200psi, but I was very leary of it. Inspector said it had to be tested and he threw the code book on me.... I would be curious to know how they will answer it when you show the man. warrenty issues.

Good idea, if you don't have a hydrostatic tester then you can use a pressure washer. I used a pressure washer on a 12" water main in Guam and it worked just fine.

Here they only have to test the water supply and the designed working pressure.

 

[Herk]

When they first came out with Polybutylene here, the state insisted that we had to have hydrostatic pumps and pump everything up to 120 or more. Maybe it was 140 - been a long time ago.

So I bought the pump and shortly later they decided that working pressure was fine. ::blert::

200psi potable water test is kinda silly. . . if it won't hold at 60psi (average water pressure here) then it won't hold at 200psi. . .here, we test domestic water piping to the "minimal working pressure" and the highest we go is 100psi on CPVC that has been installed under ground.

It might be silly but its code here....

Since this is a plumbing forum and not a construction forum all I can say is I had an argument with an inspector about windows and their method of installation vs the inspectors version. Called his boss and asked who will be responsioble if it fails. Installed them according to the manufacturers specifications. End of story!

Call his boss and ask him who is responsible then. May be surprised.

No.

Yes here they do. Manufacture installation directions override all codes.

 

[ASUPERTECH]

Most fine print in manufacters literature will state that all local code is to be followed.

 

[Ron]

Here installation instructions will supersede our code, if the code supersedes the installations instructions and you install it not to there specs, it will void all warranties.
