Signs Your Water Heater Needs Repair
- No hot water at all. On a gas tank, the cause is often the pilot or igniter, the thermocouple or flame sensor, or the gas valve. On an electric tank, it’s usually a tripped breaker, a tripped reset button or a burned-out element.
- Lukewarm water, or hot water that runs out fast. Common causes are a failed element or thermostat, a broken dip tube, or a tank half full of sediment.
- Water around the heater. A leak from a fitting, the temperature and pressure (T&P) relief valve or the drain valve can usually be repaired. Water coming from the tank itself usually can’t.
- Rumbling or popping sounds. That’s water boiling under a layer of sediment on the bottom of the tank.
- Rusty, cloudy or smelly hot water. Often a worn-out anode rod. Rusty water can also mean the inside of the tank is rusting.
- A pilot light that won’t stay lit. Usually a bad thermocouple or flame sensor, a dirty burner, or a draft or venting problem.
- A breaker that keeps tripping. On an electric heater this points to a shorted element or a wiring problem. Leave the breaker off and call us.
- An error code on a tankless unit. Codes for ignition failure, flame loss, overheating or scale tell us where to start. Read us the code when you call.
Quick Checks Before You Call
A few safe checks can save you a repair, or help us find the problem faster:
- Electric heater: check the breaker. If it tripped once, you can reset it one time. If it trips again, leave it off.
- Gas heater: make sure the gas valve on the heater is on and other gas appliances work. The relighting steps are printed on the label on the heater. If the pilot won’t stay lit, stop there.
- Thermostat setting: make sure the dial wasn’t bumped down to “low” or “vacation.”
- Leaking heater: turn off the cold-water valve to the heater, then turn off the gas or the breaker. Keep the drain pan and the area around it dry.
If you smell gas, don’t try to relight anything. Leave the house first and call your gas company or 911 from outside. Then call us.
Tank Water Heater Repair: Gas and Electric
We start by finding the real cause, not by swapping parts until something works. These are the parts we repair and replace most often on tank water heaters.
Gas water heaters
- Thermocouple: on a standing-pilot heater, this small sensor keeps the gas on while the pilot burns. When it fails, the pilot goes out and stays out.
- Flame sensor: many newer gas heaters use a flame sensor instead. A dirty or failed sensor makes the burner light and then shut off.
- Igniter: for a pilot or burner that won’t light, or an igniter that only clicks.
- Gas valve: the gas control valve and its thermostat tell the burner when to fire. A failed valve can mean no heat, or water that never gets hot enough.
- Burner and venting: we clean the burner and check the draft, so the heater burns clean and vents safely.
Electric water heaters
- Elements: most electric tanks have an upper and a lower heating element. They burn out over time, and scale from hard water speeds that up.
- Thermostats: each element has its own thermostat. A bad one can leave the water too cool or too hot, or keep tripping the high-limit reset.
- Wiring checks: for a heater that trips its breaker or has scorched wires at the elements.
Parts on every tank
- T&P relief valve: a safety valve that opens if the temperature or pressure in the tank gets too high. It should never be capped or plugged. If it drips, the valve or the water pressure needs a look.
- Drain valve: the valve at the bottom of the tank. Old plastic drain valves often start to leak, especially after a flush. We replace them.
- Anode rod: the metal rod inside the tank that corrodes so the tank doesn’t. Once it’s used up, the tank starts to rust.
- Dip tube: the tube that carries cold water to the bottom of the tank. When it breaks, cold water mixes into the hot near the top and showers turn lukewarm.
- Expansion tank: heated water expands. In homes with a pressure reducing valve or check valve, a working expansion tank absorbs that extra volume. A waterlogged one lets pressure build up, which strains the tank and can make the T&P valve drip.
Tankless Water Heater Repair
Tankless water heaters need different repairs than tanks. Most tankless problems come down to scale, ignition or flow:
- Descaling and flushing: we pump a descaling solution through the heat exchanger using the service valves, and clean the inlet water filter.
- Error codes: we read the code and the unit’s history, then test the part it points to.
- Ignition and flame failure: we check the gas supply and pressure, the igniter, the flame rod and the venting.
- Flow sensor: if the unit doesn’t fire at a low flow, the flow sensor or a clogged filter is a common cause.
For tankless installs, sizing and more on tankless care, see our tankless water heaters in Las Vegas page.
How Las Vegas Hard Water Affects Your Water Heater
Las Vegas water is hard: typically about 16 grains per gallon (SNWA, about 280 ppm), up to about 22 grains in some residential areas. In a tank, those minerals settle on the bottom as sediment. The burner has to heat through that layer, which is what makes the popping sound, wastes energy, and wears the tank out sooner. On electric tanks, scale crusts over the elements until they burn out. In a tankless unit, scale coats the heat exchanger, which can trigger error codes and lukewarm water.
A yearly water heater flush clears out sediment, and checking the anode rod keeps the tank from rusting early. Hard water uses up anode rods faster, so see our water heater anode rod guide for when to check yours. A water softener slows the buildup, and our Las Vegas hard water guide explains more.
Repair or Replace?
A repair usually makes sense when the tank isn’t leaking and the problem is a part, such as a thermocouple, flame sensor, gas valve, element, thermostat or valve. Replacement usually makes more sense when:
- The tank itself is leaking
- The hot water is rusty because the tank is rusting inside
- The heater is older (most tanks last about 8 to 12 years) and needs repairs more often
- It can’t keep up with your household anymore
We’ll tell you honestly which one we’d do, and you get the price before any work starts. If it’s time for a new heater, see our water heater replacement and installation page and what affects water heater replacement cost.
What to Expect on a Repair Visit
- When you call: tell us the brand, whether it’s gas or electric, tank or tankless, about how old it is, and what it’s doing. A photo of the label helps.
- Diagnosis: we test the heater, find the cause and show you what we found.
- Your options: we explain the repair, or when replacement makes more sense, and give you the price before we start.
- Safety checks: we check the T&P valve, the venting, the gas connection and the expansion tank while we’re there.
Brands We Repair
We work on most major brands, including Rheem and Bradford White tank water heaters, and Rinnai, Navien and Noritz tankless water heaters. When you call, have the brand and model handy. They’re on the label on the side of the heater. If the heater is still under the manufacturer’s warranty, keep your receipt or registration nearby, because some warranty parts have to go through the manufacturer.

Frequently Asked Questions
Is my water heater worth repairing, or should I replace it?
If the tank isn’t leaking and the problem is a part, like a thermocouple, gas valve, element or thermostat, a repair usually makes sense. If the tank itself leaks, the hot water is rusty from the tank, or an older heater keeps needing repairs, replacing it is usually the better use of your money. We’ll tell you which we’d do.
Why is my water heater leaking from the bottom or the top?
Leaks at the top are often a loose water connection or the T&P relief valve, and those can usually be fixed. Leaks at the bottom are often the drain valve, which we can replace, or water running down from a leak higher up. If the water is coming from the tank itself, the tank has failed and the heater needs to be replaced. Turn off the cold-water valve to the heater, turn off the gas or the breaker, and call us.
Why do I have no hot water when the pilot is on?
If the pilot is lit but the burner never comes on, the gas control valve may have failed, or the temperature got turned down. If the burner runs but the water only gets warm, a broken dip tube or heavy sediment is a common cause.
How often should I flush a water heater in Las Vegas?
With Las Vegas hard water, we generally recommend flushing a tank or tankless water heater about once a year, or more often without a softener.
Do you repair tankless water heaters? Which brands?
Yes. We repair and descale most major tankless brands, including Rinnai, Navien and Noritz. We handle error codes, ignition problems, flow sensors and scale buildup.

We answer calls 24/7 at 702-577-5505. When you call, we’ll tell you when we can be there. If the heater is leaking, shut off the cold-water valve to the heater and turn off the gas or the breaker while you wait.
