How can I get this supply hose off?

[Ak Jim]

Figured it was time to change the washing machine supply hoses just to play it safe. The cold was no problem but it looks like the hot has some corrosion. I’ve been soaking it with PB Blaster but I haven’t gotten it to budge. I can get some channel locks on it but I don’t want to put too much torque on it because I don’t want to break the plastic housing or damage the copper pipes. I figure if need be I could use the dremel with a cut off wheel to cut a slit in it. Is there any other techniques I’m missing?

I like the dremel tool idea, seems the safest way to me.

I would pick up a new box a valve in preparation to fix it correctly. You’re going to have to do it eventually, or the next owner will.

If it’s the next owner, you’re going to get dinged by the home inspector, so you’ll be paying someone else to fix it anyway.

Get a pipe wrench or pliers on the valve body and do your pulling against that instead of the pipe or housing. If the screw will come out of the knob, it'll be easier to do that.

2 pairs of pliers, hold the valve with one use the other to work the hose back and forth.

Agreed. Counter torque. Have you tried a heat gun. Protect the area with a welding blanket.

I would shut the water off to it first...I was there last winter at the SIL house.

Support the fitting on one side with a metal object while you tap lightly and repeatedly on opposite side of the part you wish to remove after soaking with penetrant a few days. It will help break the bond.
Be prepared for project creep.

What's in your water to cause that much corrosion?

Buy a pair of new valves and swap them both. I wouldn't spend a second changing that supply hose which doesn't include a new valve

 

[tarmy]

Is that valve leaking OP? Sure looks like a lot of staining on the handle and body that may mean that is failing too. As others said…careful counter pressure as you loosen the hose fitting.

Yes. I faced this situation recently. I didn't think any of the conventional loosening approaches would be at all effective. As it was it took a cut-off wheel on a die grinder and more than just one slot to get it to move.

H2O?

Mine looked worse than that after 10 years, it was really hard to get it out. I applied silicone grease on the threads when installing the new hoses.

Quickest way is probably to split it with a Dremel and little cut off wheel. Either two cuts opposite one another or one in the top they spray some penetrating oil down the split.

Not going to hurt anything if you get into the threads on the valve a little.

another good reason to buy quality hoses with all brass fittings

Steel hose ends are pure junk.
I had a garden hose i had to cut off by cutting a slot long ways and peeling it off .
Careful not to damage the threads on the valve though.

I wasn’t aware of it but there was a small leak at the top of the faucet where the stem comes out. I tightened the packing nut and it stopped the water leak. The box is pretty well hidden by the washing machine.

I wish I thought of this when I installed these hoses. I’ll always look for brass in the future.

More importantly, when you replace the hose, be sure to get braided hoses. Some insurance companies highly recommend them versus rubber or plastic. I put braided lines on everything in my house that requires a hose.

 

[Junkman]

When I installed new hoses on the washing machine about 10 or 12 years ago, I went with braided hoses, and they came with a device on the supply end that would shut off the water if the hose burst. Before I hooked it up, I put the end into a bucket and turned on the water. It shut the water off almost immediately.

I thought that at GJ, that advice only came with a full explanation of how the braided hoses you see at the store aren't really braided hoses...

Can’t help with that part. I don’t buy plumbing stuff from a big box store. I buy from my local plumbing supply house.

I've had them shut the water off when the washer valve opened to fill the washer before.....

Yep. It's fairly common.
