    Default Need adivce on replacing washer shutoff valves

    Well its happening once again but now its worse. The valves for my washing machine are leaking. But I noticed they look they are threaded/screwed on to the pipe. However there is a soldered threaded piece soldered to the copper pipe. Can these be unscrewed? Or soldered off? Could someone please tell me how to remove this?

    Where are the valves leaking? Is it at the solder joint or at where it screws in.

    You may be able to tighten up the bonnet nuts at the stem.

    Or if you replace, you can heat them and slip them off the copper.

    It's leaking at the stem, I already tried to tighten and the bonnet won't budge. Also do I have to get a new threaded piece? Or can i just re use the old one?

    Should be able to re-use the threaded adapter. Get ball valves next time. You can get an adapter that screws into the FIP threads on the ball valve for the hookup hoses.

    You may want to post a better picture where the threads meet the copper.
    It looks like you have an outside thread with inside sweat fitting.

    Those are male hose faucets soldered to a copper line. The thread is part of the faucet so it will come off when you remove the faucet from the copper. You probably WILL want to solder female threaded adapters onto the copper then screw the new hose faucets into them.

    I think i'm understanding this now, The "threaded" piece is literately in the valve and can't be physically unscrewed. Also if that being the case then I will replace the packing. Cant I just get the new bonnet/packing from a new valve that is exactly the same?

    This is a perfect example of what the average person cannot know.

    Plumbers will put together any pieces-parts that fit together regardles of whether these parts were intended to be used that way.

    It looks like you have a solid faucet intended to be threaded into a 3/4" fitting.

    It just so happens a 1/2" copper pipe will fit inside the threaded part and can be soldered there perfectly.

    Done all the time because it saves on carrying many more parts.

    Of course the picture is not detailed enough for me to be 100% sure, so...........................

    Carry on!

    To take a better picture, use a camera and put it into "macro" mode. That mode is often represented by a tulip icon. Shoot a side view.

    That confirms HJ, and I think ImOld is sure now too.

    That looks like one of those 1 fits all that is threaded on the inside and out.
    Theory only works perfect in a vacuum.
