Replacing valve question

CityKid · Apr 27, 2006

I plan on replacing all the valves in my house with ball valves. A project to last quite a while, no rush. My question is do you/would you cut the pipe or just heat up the pipe to soften the solder and remove the old valves. Clean up the pipes and replace with new, better valves.

The ball valves are usually going to be longer than the old valves, you may not have enough movement to pull the copper out of the old valves, and you will probably have some water in the lines, so you might as well cut the pipe.

It was worth a shot. Thanks for the input.

If you have the old style angle valves you can unscrew the nut under the handle and remove it and drain the water out.

Then you could unsweat the old valves and sweat on the new valves on.

You could at least try and if it didn't work then cut the pipe.

If you are referring to the valves under the sinks and toilets, then unsweat the valve, use a rag to wipe the hot solder smooth and then install compression style valves. I haven't even seen a sweat fixture valve in over 20 years, around this area.
