A puddle under the tank often means it is time for a new water heater. ASC Plumbing handles water heater installation and replacement for homes and businesses in Salinas and the Monterey Bay Area. We put in gas and electric tank water heaters, sized to how your household uses hot water. If one part failed on a sound tank, water heater repair may be the better fix.
Each job starts with a look at the old heater and the space around it. We check the gas line and vent, or the power, and put the quote in writing before work starts. For hot water without a tank, see our tankless water heaters page. Call or text (831) 262-9943 to set up a visit.
Tell us about the leak, clog, water heater or repipe and where the property is. We look at the job and put the quote in writing.
First we shut off the water, along with the gas or the power. Then we drain the old tank and disconnect it. The new tank goes in, and we connect the cold and hot water lines.
On a gas tank, we connect the gas line and the vent that carries exhaust outdoors. The relief valve gets a discharge pipe the full size of its outlet. Outdoors, that pipe ends between 6 inches and 2 feet above the ground and points down.
We fill the tank with water before the burner or the elements come on. Then we check each joint for leaks and run hot water at the taps. Remodeling at the same time? Our plumbing installation work covers new fixtures and rough-in.
The California Plumbing Code sizes a storage water heater by its first-hour rating, found on the Energy Guide label. That rating estimates the hot water a fully heated tank can supply in one hour. For a three-bedroom, two-bath home, the code's minimum is 62 gallons in that hour. We match the tank to the hour your home uses the most hot water.
A gas tank needs a gas line sized for its burner and a vent to the outdoors. An electric tank needs a circuit sized for it, and a new circuit is an electrician's job.
You will also hear about heat pump water heaters, sometimes called hybrid electric water heaters. They draw heat from the room air and can cool the space they sit in. Federal energy guidance calls for about 1,000 cubic feet of air around one. The room should stay between 40 and 90 degrees all year.
California law says every new or replacement water heater must be braced or strapped against earthquake motion. The California Plumbing Code places the straps within the upper third and the lower third of the tank. The lower strap sits at least 4 inches above the controls.
Selling a home in Salinas or anywhere else in California? The seller must certify to the buyer, in writing, that the water heater is braced.
Where a leak would do damage, such as in an attic, the code calls for a drain pan. The pan is at least an inch and a half deep, with a drain to an approved spot. The relief valve may not drain into that pan.
