I AM PUTTING A BROLIER SYSTEM IN AN OLD HOUSE AND THE MAN WANTS ALL APEX FLEXIBLE PVC RAN AND I HAVE NEVER RAN APEX, ONLY COPPER.... AND AM HAVING TROUBLE WHEN I AM PUTTING IN THE AIR TEST ON, IT IS NOT HOLDING PRESSURE...I PUT 100 PSI ON IT AND CANNOT FIND A LEAK NO WHERE EVEN USING SOAP AND WATER. ANY HELP HERE WOULD BE MOST GREATLY APPRECIATED.
Cule me in please..I never herd of apex plastic pvc pipe.But
then I dont get out much.
I would call the people that make the pipe and see what temp
/pressure its rated for.
I sure hope you not using this stuff on a steel boiler,with
out him signing off on it first.
I'm also wondering why is the customer being the one to
choose what material you should be using.
I never use plastic in my broiler only metal. If you're making garlic bread watch it close cause it burns fast under the broiler.
Wildcat, first thing is to turn off your caps. People find it offensive around here. It is harder to read with the caps on.
The problem. Pex tubing is becoming more and more popular in the hydronic heating industry. So get used to seeing it and an learn how to use it.
When testing a "wet" system it is not a good idea to use air. You will drive yourself crazy. I have found that the packing around valves will leak air but when they are wet they won't leak. Fill the system with water. You may get a drip here and there but so what. Drain the system fix the leaks then you are ready for the glycol. If you aren't using glycol what is the big yank about being so intense about leak checking?
Hey Benny, I believe the system has to hold pressure for 24 hours for inspection however I do not think its 100 psi but more like 25 psi...around here in mich. anyway.

coolwhip I believe the code here states 100psi for 30 minutes on hydronic testing. From memory, my book is in the office.
