Lukewarm Showers or Water Around the Tank? Water Heater Repair in Artesia, CA

Gas or Electric? What the Symptoms Point To

The first thing to know is which kind you have. A gas heater has a burner at the bottom, a gas line and a flue pipe going up through the roof. An electric heater has no flue and runs on a dedicated circuit. The symptoms overlap, but the causes do not.

Safe Checks Before You Call

• Look for water around and under the heater. If you find any, shut the cold-water supply valve on top of the tank and tell the dispatcher.
• On a gas heater, read the pilot instructions on the label. If you smell gas, leave the house and call the gas utility or 911 from outside.
• On an electric heater, check the breaker, but do not open the access panels, which expose live wiring.
• Check the thermostat dial. A setting knocked down can mimic a fault.
• Turn on a hot tap at a different part of the house to tell a heater problem from a single-fixture problem.

SafetyA gas smell is never a do-it-yourself problem, and a leak near the electrical connection of an electric heater needs the breaker off before anyone touches the unit. Leave the repair to a plumber.

Leaking Tank or Leaking Fitting: Repair or Replace?

Water at the base is the symptom that most often ends in replacement, but not always. A dripping temperature-and-pressure relief valve, a loose supply connection or a corroded fitting can be repaired for much less than a tank. A leak from the tank itself, or from the seam at its bottom, cannot be patched. The plumber can often tell the difference by drying the area, running the heater and watching where the first drop forms.

Ask three things. Where exactly is the water coming from? How old is the heater, which you can read from the data plate? What would replacement involve, including the permit? When the answer is a failed tank, the water heater replacement page explains the next step. If a failed tank has flooded the floor, the water damage repair Artesia page covers drying.

Flushing, Sediment and Hard Water in Artesia

Minerals settle at the bottom of every tank, and a layer of it insulates the water from the burner or element, so the heater works harder and the tank can run hot at the bottom. Flushing removes the loose layer, and regular water heater maintenance keeps it from building up. If the sediment has hardened, a flush will not clear it, which is why rumbling returns.

Scale builds faster in harder water. Golden State Water's 2025 report for its Artesia System puts hardness at about 8 to 16 grains per gallon, an average near 11. That is one utility's figure. If your bill comes from the City of Norwalk's Artesia Service Area, ask that utility for its report. At those levels, ask the plumber how often to flush your heater and whether a softener or scale filter is worth considering, which the water softener page explains.

Where the hardness figure comes from

Golden State Water's Artesia System, 2025 water quality report: hardness roughly 8 to 16 grains per gallon.

Earthquake Strapping on the Heater You Already Have

State law, Health and Safety Code section 19211, requires residential water heaters, new or existing, to be braced, anchored or strapped to resist earthquake movement, and a seller must certify it. A heater that tips can tear loose its gas and water connections. Look at your heater now. Straps should wrap the tank at the upper and lower thirds and anchor to the wall framing. If yours has none, add it to the repair visit.

Noises, Pilot Lights and Smaller Problems

• Popping or rumbling: sediment, usually cured by flushing.
• Pilot that will not stay lit: a failing thermocouple or a draft, a short repair.
• Igniter that clicks but does not light: a failed igniter or gas valve; leave it to a plumber.
• Electric heater that trips the breaker: a shorted element, replaced by a plumber.
• Water that smells like sulfur: sometimes a spent anode rod reacting with bacteria in the tank.

The relight instructions on the heater's label are the safe starting point. If the pilot goes out again within a day, the cause is not a draft.

Permits, and When Repair Becomes Replacement

Artesia's plumbing permit form names water heaters, and swapping a whole heater, including a move to a high efficiency model, is new work, not a repair. The rules for a plain repair are on the leak detection page. Ask the plumber whether the job needs a permit, and Building and Safety, (562) 865-6262, can confirm it. Ask who pulls the permit and for the final inspection record.

If a leaking tank floods the floor at night, call the same number; the homepage steps are under after-hours plumbing help.

Water Heater Questions Artesia Homeowners Ask

How do I relight the pilot on my water heater?

Follow the instructions on the heater's label. They usually involve setting the gas control to pilot, holding a button and lighting the pilot, then turning the control to on. If you smell gas, get out and call the gas utility first. If the pilot will not stay lit, a plumber should look at the thermocouple.

Should I flush my water heater, and how often?

Flushing removes loose sediment and can quiet a rumbling tank. How often depends on your water; ask the plumber to look at what drains out. Hard sediment will not flush clear, and forcing it can damage an old tank.

How long do water heaters last?

A tank heater often lasts about a decade, and the data plate shows its manufacture date. Age matters less than condition: a heater with a leaking tank has reached the end whatever its age, and a younger one with a bad part can be repaired.

What size water heater do I need, and does it matter for a repair?

The capacity is printed on the data plate. For a repair it matters little, since the plumber is fixing the heater you have. Size matters when replacing it, which is covered on the water heater installation page.
