Leaking shut-off valves are a common problem in the home that can cause a lot inconvenience and waste water. A leak in the shut-off valve can cause increased water bills, damage to your home and even mold. To avoid expensive repairs, it is important to fix the problem as soon as you can. This article will give you a step by step guide on how to repair a leaky shut-off valve.

Step 1: Shut off the water supply

It is important to shut off the water before you start any repairs. Find the main shut-off water valve and turn it off. You may have to shut off the water at the well or meter if you can’t find the main valve. To avoid accidents, it is important to make sure that the water is shut off completely.

Step 2: Remove Handle and Nut

After the water is shut off, you may begin to disassemble the valve. Remove the handle. It is usually secured with a screw. Remove the nut holding the valve stem with a wrench. After removing the nut, you can remove the valve stem.

Step 3: Check the Valve Stems and Washers

Check the washer and valve stem for wear or damage. The washer will need to replaced if it is damaged or worn out. Take the old washer into your local hardware shop to get a new one.

Replace the washer

Install the replacement washer onto the stem of your valve after lubricating it with plumbers’ grease. Make sure the washer is seated properly and fits snugly onto the stem.

Reassemble the Valve

Reassemble the valve, inserting the stem of the valve into the valve. Tighten the nut using a wrench. Be sure to tighten the nut enough to stop any leaks, but not too tight so that it damages your valve.

Step 6: Switch on the water supply

After reassembling the valve, you should turn on the water and check for leaks. If you see any leaks, shut off the water and tighten the nut until the leak is stopped.

Replace the valve

You may have to replace the whole valve if the valve is badly damaged or if the washer replacement does not solve the problem. It is best to consult an expert plumber if you are replacing a shut-off. This process can be more complex and requires more knowledge.
