Unhappy how do i replace a leaky toilet shut off valve?

The shut off valve that goes to my toilet is leaking/dripping. How do I replace it? Is this a DO IT YOURSELF type of job?

Is it a compression type or a screw on type of shut off?

Well, first of all, where is it dripping from? If it is under the handle, you need to just tighten the packing nut first... if that doesn't fix your problem, then you can work on replacing it... Make sure to hold the valve with one wrench while you tighten the nut so you dont break it off the threads...

This is a bad looking valve and it does need to be replaced.



You have a compression stop, shut the water off to the house, get a compression stop that slips over 1/2" copper pipe, I call them 1/2" comp by 3/8" angle stop like this one




Home Depot should be able to get you the correct stop, better yet once to remove it take it with you. also pick up a new supply line, 3/8" comp x 7/8 toilet supply line like this one.




Hold the back nut steady and unscrew the old stop off of there, chances are you will have to reuse the back nut on the old shut off, this won't slip off of there, use the new shut off with the old back nut. Tighten it back up and look for leaks.

When you go to screw the new stop back on the old nut however, hold against yourself so you dont strain the copper, and also, brush some pipe dope over the old compression ring, or wrap a couple wraps of teflon tape over it... That will significantly reduce the chance of a leak...
