Main shut-off valve repair/replacement in Yonkers, NY

A main valve that actually works when you need it most.

Your main shut-off valve is your first line of defense in a plumbing emergency. Unfortunately, many older gate valves seize from years of disuse or leak when finally turned. Main shut-off valve repair or replacement ensures you can close off water to the whole house quickly.

Why main valves fail

Many older homes have gate valves as their main shut-off. These use a wedge that lowers into the valve body, and after years without use, mineral buildup and corrosion can freeze them in place. When finally turned, the stem can break or the wedge can separate, leaving the valve stuck open. Packing around the stem can also leak.

Quarter-turn ball valves are more reliable because they use a simple ball with a hole through it, turning a quarter turn to open or close fully.

Testing your valve

We recommend testing your main shut-off once or twice a year by closing it and confirming water stops at a faucet. If it's hard to turn, leaks, or doesn't stop the water, it should be repaired or replaced. Knowing your valve works gives you confidence that you can stop water quickly in an emergency.
