I am replacing my old shutoff valves under my bathroom sink and toilet. How do you go about getting them off when they are soldered on? I know they need to be sweat off , but not familiar with the technique. Please help.

Normally you cut them off. Most of the time theses are compression fit. Are you sure they are soldered.

Thanks for your quick response. Yes the vales are soldered on. The house was built in 1978 and they are original. So I just need to cut them off and can use ones with compression fittings? Sounds easy enough. Thanks

If you have room to cut it, and install the compression angle valve see the picture, good luck.

I have seen these valves in Home Depot. If it sticks out a bit, cut it off. Otherwise, you have to take a torch, heat it up and pull old valve away from the pipe. Now, you can either use compression type valve or solder on 1/2" Male Adapter and screw on regular 1/2" MIP valve.

You may have a problem with compression valve since the pipe will be "dirty" from previous installation. I think the second option is better way to go.

Also, I have already seen "SharkBite" fitting type angle stop valves in Home Depot. No soldering. Just push it on to the pipe and you are ready to reconnect your water supply.

I would suggest to use the compression type of valve if it is possible, Thanks.

I agree with John,
Asking the home owner to solder on a male threaded adapter is just piling on more work. If, by "dirty" Milo means solder left on the pipe simply heating the pipe and wiping the solder off will allow you to install a compression or a Sharkbite angle stop. Good luck, Tom

Tom Or the shrkbite angle stop out yet where can I find one?

Our Home Depot carries them. But if you can't locate them locally then I'll give you a link from the internet. Regards, Tom

Our Home Depot sells them too. They are 1/2" Comp x 3/8" Comp in PC. So far, 3/8" Comp only.
