    Corroded hot water feed to washing machine
    The water feed connection at the spicket is very corroded. It is in the inset in the wall and difficult to get a wrench on. I have used Liquid Wrench and WD-40 but cannot break it loose. Any suggestions?

    Hi Fifthgear:

    You could try a BASIN WRENCH here... see picture. It can fit in tight space and has good mechanical leverage to loosen that baby... ;)

    Available at all home supply stores.

    Let us know how you make out...

    This was an excellent idea. I actually have a basin wrench and never even thought of using it. Unfotunately, I worked with the basin wrench, even used channel locks to add torque and could not break it loose. That sucker is really stuck. I'm thinking of taking a hack saw and trying to cut through the female end. Will be tricky to avoid cutting into the threads on the male end. Have you ever tried that?

    Its possible, but very risky. If you damage the threads you will be looking at more work. Try tapping on the hose connecter with a hammer(all the way around). Then try the basin wrench with channel lock again. I suggest shutting water to house off before twisting to hard on the hose connection, just in case something decides to break loose before washer shutoff..

    Also, (and I know it sounds crazy), try tightening hose, just to see if you get any movement in that direction, then back it off. Just trying to get it broke loose.

    Another good idea, but this thing seems to be welded on. Of course, on problem is the connection is facing into the wall, so I can spray WD40 into the connection. The tapping and reverse pressure don't break it loose. I will soak it again and let it sit overnight. If that doesn't give it time to soak, looks like my choices are to do the hack saw thing of cut into the wall below the valve, cut the pvc and splice in a new valve. Not fun.

    You have a good idea about using the hacksaw. I have done it many times. If you will get one of the miniature hacksaws you will have better control on how deep you cut.

    Use the saw in a way that will cut across the threads at about a 45 degree angle. Saw until you think you are getting close to the threads of the faucet. Now use a thin bladed screwdriver, put it in the slot you made and twist, if the nut pops apart you did good if not saw a few more times and try the screwdriver again. While sawing at this point saw more up at the part closest to the faucet, that way if you do get into the threads you will only saw threads at that area not in the area where the hose washer will seal. Keep sawing just a bit at a time and keep twisting the screwdriver, you might also try to get the blade under where you have sawn and pry that part up.

    Good luck and let me know if this helped.

    Man, what a job! I did saw the female end, used the screwdriver, and was able to get the nut off. It took two cuttings. Thanks for the tip! Now the corrosion is in the threads so that I can't screw on the new water pipe. I have tried using the small screwdriver to clean the threads, using WD40 and Liquid Wrench to loosen the corrosion. I am going to let it soak over night to see if I can clean the threads. Then I can tell is I damaged the threads while sawing or twisting the old nut off. Visually, the threads look OK, but we'll see. Any other suggestions for cleaning the threads?

    Very stiff wire brush, or a wire wheel in a drill.

    I ended up using a small utility knife and the stiff brush and finally got the threads cleaned. I had not damaged the threads in the sawing and am now back in business. Thought for sure there for a while I was going to have to cut into the wall and replace the spigot. Thanks for the help!
