Water Heater Repair & Replacement in Alhambra, CA

When the hot water fades early, the pilot keeps going out, or the relief valve drips, the fix is usually one part on the heater you already own. We find which part it is and repair it, and when the tank has rusted through, we replace it with a matching one in the same place.

What we do

  • Thermocouples, pilot assemblies and igniters on gas tank heaters
  • Temperature and pressure (T&P) relief valves tested and swapped when worn
  • Sediment drained and flushed until the water runs clear
  • Leaky drain valves replaced with sturdier brass ones
  • Connector, nipple and shutoff leaks traced and resealed on top of the tank
  • Like-for-like replacement: a new tank of the same fuel and similar size on the existing water, gas and vent connections
  • A once-over checkup: burner flame, draft hood, drain pan and thermostat setting

In Alhambra homes

A city report on Alhambra’s housing finds that about 77 percent of its homes were built before 1980, so many heaters here sit in closets, garages and service porches that were laid out for an earlier tank. Tight spaces make it hard to reach the drain valve or see the pilot window, and that is often why routine upkeep gets skipped. We bring short hoses and a light, and we work around what is there.

Signs a water heater needs a look

Hot water that runs out faster than it used to, rumbling or popping while the burner runs, rusty or smelly hot water, a pilot that will not stay lit, water in the pan, or a relief valve pipe that drips. Any one of these is worth a photo by text before it becomes a bigger job.

Flushing an older tank

Minerals settle at the bottom of every tank and insulate the water from the burner, so the heater runs longer to do the same work. We shut off the gas or power, connect a hose to the drain valve, and drain and refill until the water comes out clear. On a tank that has not been drained in years, we open the valve slowly and stop if it starts to clog, rather than forcing it.

Setting the temperature

The U.S. Department of Energy’s Energy Saver guide suggests setting the water heater to 120 degrees Fahrenheit, which it calls safe for most of the population. We check where your dial sits after any repair and set it where you want it.

A yearly checkup

Once a year we look the whole heater over: the burner flame should be steady and mostly blue, the draft hood should pull air in, the pan should be dry, and the relief valve should open and reseat cleanly. We also run a short drain from the bottom valve to judge how much sediment has built up, and tell you whether a full flush is due now or can wait another year.

Replacing a tank that is done

Water seeping through the shell of the tank means the steel has rusted through, and no part fixes that. If the new heater can use the same spot and hookups, we drain and disconnect the old one, set the new tank, reconnect it, fill and light it, check every joint and set the temperature, all in one visit.

What we hand off

A new or rerouted gas line, a vent that must be changed, a tankless conversion, or a new electrical circuit goes to a plumber, gas fitter or electrician, and we say so in our first reply. If you smell gas, leave the house and call the gas company.
