About Main Shutoff Valve Replacement

If your main valve will not turn, you are one leak away from a disaster.

The main shutoff is the valve that matters most in an emergency. Old gate valves corrode and seize, and many leak at the stem. If yours is stuck, hard to reach or leaking, it is time to replace it.

We install a quarter-turn ball valve, test it and show you where it is and how to use it. We show you where it is and how to use it.

Questions About Main Shutoff Valve Replacement

Still have a question?

Call (629) 276-6322

Where is my main water shutoff?

Often near where the water line enters the house, at the water heater area or a meter box outside. We can show you where yours is and mark it.

Why replace a gate valve?

They can seize or leak, while a ball valve gives a clear open or closed position.

Will the water be off for long?

We plan the work to keep it as short as possible.

Is there also a street valve?

Usually the utility has a valve at the meter. We explain how to use it.
