How to Fix a Leaking Ball Valve

You know how annoying it can be if your ball valve leaks. If left unattended, it can harm your property in addition to being a waste of water. Fortunately, repairing a leaky ball valve is an easy job that can be completed with a few simple tools and some expertise. We’ll take you through the procedures in this manual to repair a leaky ball valve and restore functionality to your plumbing.

Step 1: Shut off the water supply

You must stop the flow of water to the troubled area before you begin working on the ball valve. You can accomplish this by shutting off the valve that regulates the water flow to the ball valve or by shutting off the main water supply valve. Once the water supply has been shut off, open a nearby tap to let any water that may still be in the pipes out.

Next, you need to disassemble the ball valve. Start by removing the handle from the valve. You can do this by loosening the set screw located on the side of the handle. Once the handle is removed, you should see a packing nut that surrounds the ball valve. Loosen this nut using an adjustable wrench.

Ensure that the replacement gasket fits your ball valve properly. Replacement gaskets are available at your neighborhood hardware or plumbing supply store.

Step 5: Reassemble the ball valve

Once you have replaced the gasket, it’s time to reassemble the ball valve. Place the ball valve back into the valve body and tighten the packing nut with your adjustable wrench. Replace the handle and tighten the set screw.
