What Customers Say
Not every failing water heater needs replacing. A bad thermostat, heating element, igniter, anode rod or relief valve can often be fixed for far less. The one repair that does not exist is a leaking tank body. We tell you which you have before any work starts.
The goal is to find the real cause, not swap parts until something works. If a repair makes sense for the age and condition of your heater, we fix it. If it doesn't, you hear that too.
When to Call About Water Heater Repair
- On gas heaters this is often the igniter, pilot or gas control. On electric heaters, an element or breaker.
- A failing thermostat or one burnt-out element in an electric tank is a common, fixable cause.
- The pressure relief valve may be worn, or pressure in the system is too high. Both need checking.
- Usually a reaction with the anode rod. Replacing the rod or changing its type often solves it.
- A dirty burner, failing thermocouple or venting problem can cause it. Venting issues are a safety concern.
- Scale in the heat exchanger, gas supply or venting are the usual suspects.
- Sediment from hard water. A flush may help if the tank is not too far gone.

Water Heater Repair in the East Valley
Hard water is behind a lot of East Valley water heater trouble. Sediment builds up in tanks and scale builds up in tankless heat exchangers. Summer heat in garages and closets also wears down thermostats, gas controls and connections faster than in milder climates.
A failed water heater deserves an honest conversation, not a high-pressure sales pitch. Sometimes that conversation ends with a small repair. Sometimes it ends with a plan to replace the tank before it leaks.
Water Heater Repair by City
Common Questions
- Is it worth repairing an old water heater?
- It depends on the part and the tank's condition. Replacing a thermostat, element, igniter, anode rod or relief valve is usually worthwhile. If the tank is leaking, heavily corroded or near the end of its life, a costly repair may only delay replacement. A plumber can tell you which it is.
- Who repairs water heaters in the East Valley?
- Renova Plumbing & Drain repairs gas and electric, tank and tankless water heaters in Gilbert, Chandler, Mesa, Queen Creek, Tempe and Scottsdale. The Renova team diagnoses the heater first and tells you honestly whether a repair or a replacement makes more sense.
- Why does my water heater relief valve keep dripping?
- Either the valve is worn, or pressure or temperature in the tank is too high. High pressure is common where a pressure regulator stops heated water from expanding back into the main line. Replacing the valve alone may not fix it. The system pressure should be checked too.
Frequently Asked Questions
It depends where the leak is. A leak from a fitting, valve or connection on top can usually be fixed. Water coming from the tank body itself means the inner lining has failed, and that cannot be repaired. We'll find the source and tell you which it is.
On an electric heater, one failed element or thermostat is the usual cause. On a gas heater, it can be the gas control, burner or thermocouple. Heavy sediment from hard water also reduces how much hot water the tank delivers. A diagnosis narrows it down quickly.
The anode rod is a metal rod inside the tank that corrodes so the tank doesn't. Once it is used up, the tank starts to rust. Hard water and softened water both affect how fast it wears. Checking and replacing it can add useful years to a tank.
When the tank body leaks, when the tank is badly corroded, or when a costly repair is needed on an old heater. In those cases the money is better spent on a new heater. We explain the reasoning so the decision is yours, made with the facts.
Yes. Common tankless problems include scale in the heat exchanger from hard water, gas supply shortfalls, venting issues and sensor faults. Many are fixed with a flush or a part. We read the error code, test the unit, and explain what is wrong before recommending anything.
