Why is my toilet shut off valve leaking?
The most common problem for a toilet shut-off valve is that it can develop a leak. Leaking is caused by loose packing nuts on these valves. In some cases, this may also be caused by minerals deposits on the washers. A leaking shut-off valve doesn’t necessarily mean it always needs replacement.
How do you fix a leaky supply valve?
First shut off the water to the leaking water valve. Next remove the handle from the stem and then loosen and remove the packing nut. Remove the old washer and slide on the new one. Reinstall the packing nut, tighten lightly with a wrench (don’t over tighten at this or any other point) and reattach the handle.

Should toilet water valve be open all the way?
All the way open. The valve controls flow not pressure. Those angle stop valves should be fully open because they have a back seat to prevent leaking in case the stem packing leaks.
Can a water shut off valve go bad?
You can spend time rebuilding the old valve, but the problems will just reappear years from now. The best way to deal with bad valves is to replace them with modern quarter-turn ball valves. They rarely lock up, leak or wear out and best of all, they’ll take just an hour or so to install.
Can you repair a leaking PVC ball valve?
You can replace it fairly easily. Turn off the water and cut the valve off about 1 1/2 inches away from each end. Then glue in a new one with slip couplings.

How do you replace a water shut off without turning off water?
Although it’s not advised, you technically can replace a faucet without turning off your water. To do so, you need to turn on faucets elsewhere in your house to reduce the amount of water pressure going to the faucet you want to replace.
