How to bench test copper plumbing?

uvascanyonJuly 18, 2013

We have a cabinet install next week and not sufficient time to finalize the connections below the house to the water supply and drain. We'd like to have the drain stub-out in place and the hot and cold water pipes sticking-out of the wall, then after the cabinet install make the proper connections in the crawl space...

We would feel better knowing that the copper pipes I sweated are leak-free before hanging the drywall and the cabinet install.

What comes-to-mind is sweating on a fitting to receive a hose, cap the other end, and see if it holds. Other ideas?

Where H&C are stubed out,go ahead and install angle stops. To allow connecting air pressure and psi guage at angle stops,solder on male or female pipe thread fittings to accomindate pipe thread angle stops. You can use the pipe threads to connect air fitting. Alternatly,you could just solder the stops to stub outs but make sure you know how you plan connecting air where facuect supply lines will connect latter. Beg,borrow,buy or steal a Dutch Finger to plug other end of H&C lines.

You are most welcome. BTW,the best and most common brand is "Jet Sweat" and many plumbers say Jet Sweat regardless the mfgr's name. Great quility but pricy.

Ingenious. For one time use, I can't justify the cost, but what a neat tool. For those who don't know (like I didn't previously), see the link below...

Thanks again klem1.
