How water heater installation works in Santa Ana

We install tank and tankless water heaters in Santa Ana, sized to how each household uses hot water and completed to California code.

Santa Ana's hard water builds sediment in tanks, and many heaters in older homes here are past their expected life.

When to call for water heater installation

Think about a replacement when the unit is 10 to 15 years old and giving repeated trouble, hot water runs out sooner than it used to, the hot water is rust-colored, the tank is corroded or leaking at the base, or a repair would cost nearly as much as a new unit.

What Santa Ana homeowners should know

One of the county's densest and oldest cities, with many homes built before 1970.

  • Built before 1940Galvanized steel supply and cast iron drains, in Floral Park, French Park, and Downtown. Both are past their rated life, and clay laterals here are exposed to roots from street trees.
  • 1940s to 1970sCopper supply with cast iron or ABS drains. Hard water speeds up pinhole leaks in copper, and aging cast iron stacks in apartment buildings clog often.
  • Built after 1980Plastic supply and drain lines, around South Coast Metro and newer tracts. More resilient, though slab foundations still carry slab leak risk.

Water hardness

The City of Santa Ana supplies the water, which is hard. The city publishes the current figure in its annual water quality report. Regular water heater flushing helps, and a softener is worth considering on older copper or galvanized lines.

Water Heater Installation questions in Santa Ana

What Santa Ana homeowners most often ask us about water heater installation.

Tank or tankless: which is better for a Santa Ana home?

It depends on the size of the household and how you use hot water. Tankless units use less energy and do not run out, which suits larger households. Tanks cost less up front and are simpler to service. We look at your home before recommending either.

How long does a water heater installation take?

Most installations take two to four hours. Tankless jobs take longer when the gas line or venting has to change.

Do I need a permit to replace a water heater in Santa Ana?

A water heater replacement in California generally requires a permit and inspection. We tell you at the estimate what applies and how it is handled.

What customers say

★★★★★

Great experience with Miguel and Steven! Fixed my stubborn kitchen sink clog. Very informative and respectful of my home in addressing the issue. Highly recommend!

I had an excellent experience with SoCal 1 Plumbing! Eliass came out to clear a blockage in my kitchen line by snaking it through the outside wall clean-out, and everything was done efficiently and with great care. He also installed new tubular drains under my kitchen sink to stop the leaks I’d been dealing with. The work was high-quality, and they even provided a 1-year warranty on parts and labor, which gave me peace of mind. Highly recommend their professional and reliable service!

I had a plumbing issue that needed to be repaired sooner than later. Miguel came out and knew how to fix it immediately. Miguel was professional, friendly and knowledgeable. I won't hesitate to call them in the future.
