Signs your water heater needs service
- The electric side works but the gas side will not light, or vice versa
- The unit lights, runs briefly, and then locks out on fault
- Water is lukewarm no matter how long the unit runs
- Water leaking from the bottom of the compartment or around the access door
- A rotten-egg smell from the hot water only
- A tankless unit that cycles between scalding and cold as flow changes
What the service covers
Gas side diagnosis
Gas pressure, igniter and electrode gap, burner tube cleaning, thermocouple or flame sensor, gas valve, and the control board. Insect nests in the burner tube are a genuinely frequent cause here and cost nothing to clear.
Electric side diagnosis
Heating element testing and replacement, thermostat and high-limit reset, and the wiring between them — the classic case where a rig has hot water on shore power but nothing on propane.
Anode rods and flushing
Anode replacement on Suburban tanks and a full flush to clear the sediment that steals capacity and causes that rotten-egg smell in hot water.
Leaks and tank failure
Finding whether the leak is a fitting, the drain plug, the pressure relief valve, or the tank itself — the last of which means replacement rather than repair, and you get told that plainly.
Bypass valves and winterizing hardware
Repairing bypass valve assemblies that leak or fail to divert, which is what leaves people with no hot water after a winterization or with antifreeze in the tank.
Replacement and tankless upgrades
Full unit replacement when repair does not make sense, including on-demand tankless conversions with the gas and water plumbing done properly rather than adapted.
The cheap fixes are the common ones
A large share of no-hot-water calls come down to a tripped high-limit reset, a failed heating element, a dirty burner tube, or an igniter electrode sitting at the wrong gap. All four are inexpensive parts or no parts at all, and all four are same-visit repairs.
What matters is testing in the right order. A water heater that works on electric but not gas is telling you something specific, and so is one that lights and then locks out after thirty seconds. Those two symptoms point at completely different components.
Central Texas water is hard on tanks
Mineral content in this region builds sediment in a water heater tank faster than a lot of owners expect. Sediment insulates the bottom of the tank from the burner, so recovery slows and capacity drops, and it accelerates the anode rod consumption that protects the tank lining from corrosion.
Annual flushing and anode replacement on a Suburban tank is straightforward maintenance that meaningfully extends tank life. Skipping it for years is how a repairable water heater becomes a replacement.
