Why is my water heater not working?
Most water heater problems come down to a few parts. No hot water on a gas unit is usually the pilot, thermocouple, or gas valve. On an electric unit it is usually a heating element, thermostat, or tripped breaker. Rumbling or popping is sediment in the tank, and Phoenix hard water builds it quickly.
A leaking valve or fitting can be repaired, but water coming from the tank body means it has rusted through and needs replacement. Fast Layne Plumbing repairs gas, electric, and tankless water heaters across the Phoenix metro. We confirm the cause before recommending a repair or a replacement, and we tell you when a repair no longer makes sense for the age of the unit. Gas units also get a safety check of the venting and gas connections. If you ever smell gas, leave the house and call 911 or Southwest Gas before you call us.

Our water heater repair services
We diagnose and fix common issues, such as faulty thermostats, heating elements, or pilot light failures. This hot water heater repair service covers all models and includes safety checks, flushes, and replacement of worn parts to keep your unit working efficiently.
Tankless units can deliver endless hot water, but still need service when flow sensors or burners fail. Our tankless water heater repair includes descaling, gas valve testing, and digital error code diagnosis. It’s a smart service to pair with upgrades like sink and faucet installation or shower and bathtub installation for consistent hot water across new fixtures.
Electric units often fail due to tripped breakers, failed elements, or sediment buildup. We provide full electric water heater repair, verifying voltage and resistance, replacing faulty components, and flushing tanks to restore consistent heating. Before wrapping up, we test the unit to confirm proper operation.
We offer fast gas water heater repair if your pilot light won’t stay lit or your water takes forever to heat. Our team checks thermocouples, burners, and gas connections to ensure clean water heating. We also test for gas leaks to avoid hidden safety issues.
We provide reliable commercial water heater repair for businesses that minimizes downtime and keeps hot water flowing. Whether it’s a restaurant, rental property, or retail shop, we respond quickly and carry the right tools to get your larger-capacity system back up and running.

Reliable, safe performance
Regular maintenance of your water heater is essential for its reliable and safe operation. We check for leaks, flush the tank, and examine every component to identify problems early and address them before they become serious.
Lower energy costs
The efficiency of a well-maintained water heater may result in reduced energy costs. You can optimize your water heater’s energy efficiency and reduce your monthly utility costs by maintaining it in good working order.
Fewer breakdowns and repairs
Regular maintenance guards against expensive future repairs and unplanned malfunctions. By addressing minor issues promptly, you can extend the lifespan of your water heater and avoid the inconvenience of running out of hot water.
What causes water heater problems in Phoenix homes?
- Hard water sediment. Phoenix-area water is commonly 200 ppm or higher, per City of Phoenix water quality reports. Minerals settle at the bottom of the tank, insulate the water from the burner or element, and cause popping noises.
- Garage and attic heat. Heaters in hot garages and attics work in a harsh environment, and fittings and valves age faster.
- Worn anode rod. The anode rod protects the tank from rust. Once it is used up, the tank starts to corrode.
- Failed thermostat, element, or thermocouple. These are common, repairable parts.
- Pressure problems. A relief valve that drips can point to high water pressure or thermal expansion.
How is a water heater repaired, step by step?
- Check the symptoms and the unit. We read the data plate for the age and model and ask what you have noticed.
- Make it safe. We shut off the power or gas and water as needed.
- Test the parts. We test the thermostat, elements or burner, thermocouple, gas valve, and relief valve to find the failed part.
- Repair or flush. We replace the failed part and flush sediment from the tank if needed.
- Run and verify. We check temperature, pressure, venting, and for leaks, including gas leaks on gas units.
Do water heater repairs need a permit?
Parts repairs usually do not. Replacing the whole heater normally does. If we find the unit should be replaced, our water heater installation team handles the permit and code requirements. Gas supply problems may call for gas line repair.
When should I call a plumber about my water heater?
- No hot water, or hot water that runs out much faster than it used to.
- Water around the base of the tank, or rust-colored hot water.
- The relief valve is discharging or the pipe from it is dripping.
- Loud popping or rumbling from the tank.
- A smell of gas. Leave the house first, then call 911 or Southwest Gas.
A tank that is actively flooding is an emergency plumbing call. Shut off the water to the heater and call us.
We fix it right the first time, with upfront pricing before any work begins.
