In my home, I am also facing this issue, and I wanted to know the reason for the main water shut off valve leaking outside. So, I researched online and found a few common causes. It can happen because of a damaged pipe connection, loose fittings, or even leakage near the handle area. I am sharing all the possible causes I came across below.
Why is the Outside Main Water Valve Leaking?
The rubber seal inside the valve may have become old and weak.
Water can leak if the joints or connections are loose.
An old valve may have rust or small cracks that let water escape.
High water pressure can push water out through weak spots.
A broken or cracked pipe near the valve can also cause leakage.
After researching, I understood the common causes and realised that finding the exact reason is important to fix the problem properly.
