Yes, usually. In one development we're often replacing 40-year old angle stops because the existing are frozen open. We strongly prefer not to change anything in the walls - we pay cash money for a couple of hours of building water shutdown, to replace a dozen angle stops and a couple shower valves, and we have to hustle. Sometimes the old fixture was cranked on and the olive is mashed into the copper. Even if we can get the old olive off without making things worse the new one doesn't always seat very well. Sometimes the old olive stays.
Yea. My opinion is he's the one that's nuts and does not understand how they work.
That happens pretty often when a lubricant ain't used. People struggle to tell how tight them have the olive then over tighten/strangle it. I use plumbers paste for 2 reasons. One it lubricates the surfaces and it fills voids in the surfaces. PTFE tape can do the same thing as the Teflon helps the threads slip better but it pulls it self from surfaces that touch tight. Paste stays put much better.CarpenterSFO said:
Screw that go to a welding shop, get some dry ice and freeze the line. Cut the pipe and propress on a new shutoff, just leave the old pos on there.
Have you actually done that before or are you kidding?Inner10 said:
It's an idea.... Some of the 11 angle stops are right on tees running up the full height of the building. It would be the end of my business here.
It does work. I have used pipe freeze kits a few times in the past. Sure gets worrying when you start heating the pipe up lol.dielectricunion said:
Yes dry ice does work ,that's what we use when replacing a water main in a finished area .
Never, I just watched in amazement as a plumber did it.
We always subbed out the pipe freezing to a company that specialized in it, it put the burden of liability on them instead of us.
