Washing Machine Valve Leakage

You need to be more clear. Provide a photo indicating leaking spot?

Thank you for your reply.
I haven't used it for a few months. When I turned on the SYMMONS washing machine valve, some water squeezed out from the switch. Luckily when I turned it off, no more water squeezed out.

So buy a new valve and replace it? Whats the question?

Have you tried to tighten the screw on the valve shut-off handle? If that doesn't stop the seepage, I would replace the valve.

Please edit this thread title from "Value" to "Valve"

I tried , but no use.
I am thinking to replace the valve, but I am worry that this is a high pressure water pipe input. Somebody told me it has 500 pound pressure.
I do not know how to replace it safely under this high pressure.

LOL - no water pipe in your house has 500 pounds of pressure. Perhaps 50 or so.

You can't replace a valve with 1 pound of pressure - you need to turn the water off and drain the pipes.

Call a plumber before you flood your house.

If you mess around with this valve it could start leaking. And I'm betting you don't know where the main shut-off for the water is to your house to stop it.

If you want to take this on - and I'm all for home owners learning to DIY, first watch some YouTube videos on rebuilding a water supply valve. You likely need some new o-rings.

Then, once you have the parts you need, you need to shut the water off to this valve. Chances are it means you need to turn the water main off which should be where the water comes into your basement. This turns all the water off for your entire house.

Then open all the faucets in your house to drain the water out of the pipes and release the pressure.

Then disassemble the valve and repair as per the self-training you got on YouTube.

While you're at it replace those junky black rubber supply hoses to your washing machine with new braided stainless lines.

Or - call a plumber.

Here's the video on how to replace the valve.

Great advice torontotim. Seeing members go the extra mile to write detailed instructions and even sourcing an exact video tutorial is what keeps me coming back to these boards. ( It certainly isn't the snide "I'm so much smarter than you." comments sometimes posted.) Way to go the extra mile. And OP, this guy just took the time out of his day to give you a detailed explanation to your question. It would be a good thing to at least "thank" him.

Torontotim thank you very much for your information. Since I haven't come to the forum for a while and the email of reply sent to my junk folder, I did not seem your reply.
It is very helpful and clear. It looks like very easy, but I have some bad experience of flooding, I am afraid that I will messy up with it. The valve do not leak when it is off. I did call plumber for a price quota, it cost me $170 labour and $135 for part. This is the plumber that condo management want me to use, I may try to search another cheaper one.
Once again thanks Torontotim, you gave me the best answer.

Besides, one more question, do you have any ideal how to remove this sliding door bottom guide. The sliding must be remove before I move out the washer.
