Why is the shut off valve on my toilet leaking?

By Jessica Hardy

Why is the shut off valve on my toilet leaking?

The plumbing supply shutoff valves behind toilets or under sinks can go for years without being turned off and then reopened again. That inactivity can cause the neoprene washers to become either brittle or crusted up with mineral deposits, and they lose their ability to seal leaks.

What is the shut off valve behind the toilet called?

Stop Valve: This is also called the toilet supply valve because it controls the fresh water supply going into the tank. It is usually located behind the toilet near the floor, and turning it off is another way to stop an overflowing toilet because the tank cannot fill once it is turned off.
