Do ball valves need lubrication?
Ball valves are not very high maintenance parts. Other than worn O rings that seal the ball inside the valve body, keeping the valve clean and free-turning with a little lubrication is all it needs. It’s when a valve looses its lubrication and debris or corrosion builds up that it can become hard to turn.
How do you free up a stuck PVC ball valve?
If it is still hard to turn, tap the valve slightly with a hammer, and place a pipe wrench around the handle to turn it (position a rag between the handle and wrench to keep the wrench from chewing up the handle). Keep attempting to turn the handle on and off for a few minutes.
Can you lubricate PVC ball valve?
