how to loosen a water faucet that screws onto a thin threaded copper pipe ?
The pipe size is 10mm, and you will need to use a Sink spanner to undo it. You only need the one tool, as you should be able to steady the faucet with your other hand. Turn it anti Clockwise. When you replace the faucet, make sure the fibre washer on the end of the copper Pipe is still there, and in good condition. If it is not, change it to stop any leakage of the connection. Do not overtighten the joint, or you will crush the fibre washer. just hand tight, and a half turn with the Spanner.
If the pipe is threaded (i.e. a pipe similar to galvanized but made of copper) a pipe wrench should be able to loosen it sufficiently. However, because you call it a THIN copper pipe, I'm assuming you have a copper line with a sweat fitting threaded adapter. Sometimes a little heat will loosen the threads. However, in the case of a sweat fitting, too much heat will soften the solder and likely slip before the threads come loose. Also keep in mind that applying heat can damage any plastic or rubber parts. If you can, disassemble the valve before you apply any heat. If it IS a sweat fitting, just go ahead and unsolder it. They are cheap enough to replace and you are more likely to have an easier time just putting a new fitting on the end of the pipe. If you try to FORCE the valve off the threads you could twist the pipe and kink it. Then you would be replacing a whole lot more than a cheap threaded sweat fitting. Good luck. )
Hello rm, This is Shecandoit22 from Home Depot. The easiest way is to use 2 pipe wrenches. One on the end of the pipe and the other on the faucet. Turn them in opposite directions and the faucet should turn right off. I hope this helps.
