What you may be seeing
Main Water Shutoff Valve usually starts with visible clues.
Start with the symptoms you recognize. We will help separate the likely plumbing system involved before recommending work.
Valve is hard to turn
A stiff or seized valve may not be reliable when you need it most.
Valve leaks when operated
Some old valves begin dripping when moved, especially after years of not being used.
Water does not fully shut off
If water keeps flowing, the home may not be protected during a leak.
Old gate valve feels unreliable
Older gate valves can spin, seize, or fail to close fully.
Damp or corroded shutoff area
Visible corrosion or dampness near the main shutoff should be checked.
You want reliable control before other work
A shutoff upgrade can make future plumbing work safer and cleaner.
Diagnosis first
The main shutoff should be assessed before forcing it.
