When a water heater problem is an emergency
Cold showers are a nuisance. Water leaking from the tank, a gas smell or a hot, popping unit are different.
- Water on the floor around the base of the tank, especially if it keeps coming.
- A rumbling or popping sound from the tank, which can mean heavy sediment and overheating.
- A pilot that will not stay lit, with any smell of gas in the room.
- Rust-colored hot water, or hot water that is far hotter than normal at the tap.
What to do while you wait
If you smell gas, leave the building and call the gas utility or 911 before you call us. Do not flip switches or light anything.
For a leak with no gas smell, close the cold supply valve at the top of the heater, turn the heater off at the gas control or the breaker, and protect the floor.
Why a gas heater stops heating
Gas tank heaters fail in a handful of predictable ways. A dirty or failing thermocouple shuts off the gas when the pilot flame is not hot enough. A weak igniter or a clogged burner assembly prevents a clean light. A failed gas control valve, which is the unit with the dial, stops the burner for good.
We check the flame, the venting and the gas supply before we replace any part. A backdrafting vent can be a safety issue as well as a cause of a lost pilot.
Why an electric heater stops heating
Electric tanks have two heating elements and two thermostats. When the upper element fails the tank gives a short burst of hot water and then runs cold. When the lower element fails the hot water runs out quickly.
A tripped high-limit reset button on the upper thermostat is common. Resetting it once is fine, but if it trips again something is wrong and the heater needs testing instead of another reset.

Call (480) 741-9332Sediment, rust and the anode rod
A tank heater has a sacrificial anode rod that corrodes so the steel tank does not. Once the rod is spent, the tank itself starts to corrode, and sediment collects on the bottom and insulates the water from the burner or element.
Flushing a tank and checking the anode rod can extend the life of a younger heater. On an older heater, a flush can loosen a leak that was held shut by scale, so we tell you that risk before we start. If the tank itself is leaking, no repair saves it.
Florence Water supplies groundwater according to the Town of Florence water quality page, and the Consumer Confidence Report does not state a hardness figure. If you have a water softener or filtration system, tell us. It changes how fast scale forms.
Water heater leaks: tank, fitting or valve
Not every puddle means a dead tank. A weeping inlet or outlet fitting, a dripping temperature and pressure relief valve or a leaking drain valve can often be repaired, and the tank is fine.
- Water around the top of the tank usually comes from a fitting or the relief valve.
- Water at the bottom with a wet jacket or insulation points to a leaking tank.
- A relief valve that drips regularly can signal high pressure in the house and not a bad valve.
When the leak is a hidden supply line behind a wall or under a slab, it is a leak detection job. If the tank has failed, we move to replacement and explain the options on the spot.
Repair or replace: a simple way to decide
Age, leak location and the cost of the part drive the decision. This table is how we frame it for you.
| Situation | Usual answer | Why |
|---|---|---|
| Tank leaking from the shell | Replace | A corroded steel tank cannot be patched. |
| Bad element, thermostat or igniter on a younger unit | Repair | The part costs far less than a new heater. |
| Old unit needing a gas valve and a vent repair | Often replace | Money goes into a heater near the end of its life. |
| Fitting or relief valve leak | Repair | The tank itself is still sound. |
| Heavy sediment and rust-colored water | Depends | A flush may help, but rusty water can mean tank wear. |
What water heater repair costs and what moves the price
You get a number before we replace a part. These are the factors that change it.
A thermocouple or element costs much less than a gas control valve.
The two types use different parts and different testing.
An older tank may be better replaced than repaired.
A cramped closet or an attic unit adds time.
A missing pan, drain line or expansion tank may need to be addressed with the repair.
Want your real number? Call (480) 741-9332 and tell us the make, the fuel type and what it is doing.
Code note: relief valves and safe repairs
Both the UPC and the IPC call for a temperature and pressure relief valve with a discharge pipe on storage water heaters. A repair that touches the gas train, the venting or the relief valve is a safety item, and we explain what we changed and why.
Water heater repair near the Townsite, Hunt Highway and Anthem
Garage and exterior closet installs are common in Florence, and a slow leak can soak a slab edge long before anyone sees it. We serve homes in town and at Anthem at Merrill Ranch, and dispatch also covers Coolidge and San Tan Valley.
Tankless units have their own faults and maintenance. See tankless water heater service for flushing and error-code work.
Questions about water heater repair in Florence
Yes. The line is staffed 24/7 and a leaking tank or a gas smell near a heater is treated as urgent. For gas odor leave the building and call the gas utility or 911 first. Then call us.
On an electric tank that usually means a failed upper or lower element or a tripped thermostat. On a gas tank, a dip tube problem or heavy sediment can do the same.
If the pilot lights easily and stays lit, fine. If it will not stay lit, or you smell gas, stop. A pilot that keeps going out can mean a failing thermocouple or a venting problem.
Dry the heater and the pipes, then watch. Water that appears at a pipe connection or the relief valve is repairable. Water that seeps from the bottom of the jacket usually means a leaking tank.
Yes. Tankless units have error codes, flow sensors and scale buildup that tank heaters do not. Details are on our tankless water heater page.
Yes. Landlords and property managers can call to arrange a visit with the tenant, and we note access instructions before we arrive.
