Old Tubing

@ March 22, 2010 3:45 PM in Old Tubing

I have some tubing that is from 1984ish. The only info I can get directly off of the tube is: 3200 upc, sdr11, 180deg., 100psi, B1378, IAPMO IS 22-8-W8, 1/2"otc, 5/8"od, C 07-18-84.
The tubing is a medium grey color and is used for infloor heating in concrete.
What is it? Is it an oxygen barrier tubing? any info would be appreciated.
Thanks,
Bob

Can someone post the link or contact info for a guy that makes the pnumatic tool to put 5/16" pex into Viega climate panels? I saw it on The Wall a few months ago but I can't find anything on it now. I seem to remember it being called the "hound dog" or something like that.
Thank you.

Thanks again

I'll pump away next time. Why not zone valves on the return? It's a valve right. It never has blown the pressure relief, why would it? The autofill is in the bottom of the air seperator not the inlet to the pump.
Anyhow, it didn't work before I got there and now it does.

This one is from the fall of 2008. Client said he needed a new boiler. I did a connected load vs. heat loss to determine the boiler was sized properly. Reworked the piping and pump and it was awsome last winter.
