Leaky Shut Off Valve - Need help


Hi,

I have replaced the shut=off valve unit and it still leaks. The Lowe's guy said that i do not need teflon or packing material to keep it from leaking, but obviously, something is wrong. I have the type of shut off that goes onto copper tubing. There is a packing/conversion nut that attaches to the shut-off valve. The leak is coming from that connection.

Please help!

If it is threaded, it needs joint compound of some type. It can be teflon tape or paste type pipe dope. Not knowing this is one reason he is working at Lowes and not out actually doing the work.

Yea, I know what you did.

You didn't slide the valve on the pipe enough before tighting the nut with the feral in it.

What you need to do is the following:

1) Shut the water main off

2) drain water in that sink etc , have a pan under the valve

3) loosen the packing nut a few turns.

4) take a mallet or small hammer and tap the valve in more, so the pipe slams home inside that valve

5) re-tighten the valve and make sure to use to wrenches, ITS NOT tight enough until your hear it start to squeak

MAKE sure to use two wrenches , One to turn the valve nut and One to hold the valve. You will have to tighten this valve pretty tight

Here is the valve you have correct? ( Come in rough brass and chrome )

Its called a compression angle stop

Leaky Shut Off Valve - Need help


Good Morning! - First Post

I shut off the valve to our toilet this morning and when I turned it back on it is leaking a steady drip. If I turn it off, no drip. I'd assume that there is something wrong with the seal around the threading? I have little to no experience with plumbing. Is this something I can fix on my own?

Thanks!

Find the leak first. The leak can come from different things ... check the flush valve, the seals underneath on the flexible pipe or the seal coming from the shut-off valve itself. It could be leaking from where the bowl connects to the tank ... shutting of the water will stop most leaks.

My toilet was leaking from the flush valve and the shut-off valve. It's really not that hard to figure out and repair. I called a plumber and he wanted $300. That was enough motivation for me to try and by george, I did it!! If you have to replace the shut-off valve, then turn the water off from the curb. But first, touch the pipes and feel around under the toilet to see where it is wet. Before you do anything, clean the toilet area very well. That will help! You need two wrenches ... Home Depot sells something specific for pipe repair.

Hopefully, you can find Wethead .., he knows his stuff if you get in there and need greater details.

Is it the valve leaking? It sounds like that's what you're saying.

Is the leak coming from around the stem to which the handle is connected?

If so, you may be able to make it stop by opening the valve all the way, as far as it will go. You can also try tightening the nut around the handle stem just a little.

But more likely you just need to replace the valve, which will require turning off the water. Replace the hose to the toilet at the same time. These things aren't hard, but they're easy to mess up with unpleasant consequences, so if you know someone who's handy, it might be best if he or she can help while you watch and learn.

#3: I assume you meant "compression nut?"

Yes, sorry about that, I did mean compression nut but when I was writing that I was probably looking at the packing nut or thinking of how a lot of the times people replace the valve when they just could have tightened the packing nut.

Thank you for the correction, and once again sorry about that ,
