It’s okay to be frustrated about a stuck water valve. But it can be fixed pretty quickly without hassle. Follow these steps and you’re good to go:

Step 1: Turn Off The Water Supply

First, turn off the water supply at your home at the main shut-off valve. Take some time to make sure there’s no water in the pipes. Then try moving the faulty valve again. 

Try to loosen the valve by moving it with your hands. Apply some pressure and try to turn it on or off. If it works, you’re good to go. If it doesn’t, go to step two.

Step 2: Use Wrench and Lubricant

For this step, you’d need some good-quality y lubricant and a pipe wrench. First, apply lubricant all over the valve and let it rest for about 20 minutes. 

Make sure the lubricant has reached everywhere. Especially, the part where the handle enters the actual body of the valve. 

After the lubricant has been set, try moving the valve with your hand again. If it still doesn’t move, tap the head lightly with a hammer to loosen it up.

Now, take your pipe wrench and try moving the valve on and off. Check if the water is turned off. This is because not turning off the water supply beforehand can be troublesome.

We recommend you to  place a piece of cloth or rag between the rag and the handle. This will protect the valve from damage.
