West Coast Heating Air Solar & Plumbing installs and replaces main water shut-off valves in San Diego homes, along with automatic leak shut-off systems that close the supply on their own when they detect a problem. When a pipe bursts or a supply line lets go, the speed at which you can stop the water decides whether you are mopping a floor or replacing one.

In most San Diego homes it is where the supply line enters the house, often near the front hose bib or garage, sometimes in a small ground box. If you cannot find it, we will locate it and label it.
Yes, once or twice a year. Close it and open it fully to keep it from seizing. If it will not turn, do not force it; call us.
Sensors placed near likely leak points signal a motorized valve on the main line to close when they detect water, and many systems also send an alert to your phone.
Yes. We can install a dedicated house-side valve so you never need a meter key to stop the water.
Most replacements take one to two hours, and the water is only off for part of that time.
We locate your main shut-off, test whether it closes completely, and look at its condition and accessibility. Many older homes still have gate valves with round handles that corrode internally and never seal fully again. We typically replace those with full-port quarter-turn ball valves that close with a single motion and do not restrict flow.
If your home lacks a house-side shut-off and relies on the meter box, we can add one where the supply enters the house. For extra protection, we install automatic shut-off systems that pair a motorized valve on the main with leak sensors near water heaters, washers, and sinks, and many of them can alert your phone. You get a written price before any work starts, and we restore and test the water before we leave.
Houses across San Diego County often have main valves set in the ground near the front hose bib or hidden behind landscaping, which makes them hard to reach in a hurry. Hard water and decades of disuse leave many of these valves frozen in the open position, and owners usually discover that during an emergency.
Shut-off services we provide:
A main valve that closes on the first try, in a spot you can reach, limits water damage to minutes instead of the half hour it can take to find a meter key and reach the street. Automatic systems go further by shutting the water off while you sleep or travel, before a slow leak turns into a ruined floor or mold behind the walls.
Putting this off usually becomes expensive at the worst moment. Insurance claims for water damage are among the most common for homeowners, and a valve that fails during an emergency leaves you waiting for the water department while water keeps running.
If your main valve is old, stuck, or hard to find, call (619) 349-4189 and we will make sure you can shut the water off fast.
