Water Heater Repair
If the tank is leaking or the relief valve is discharging, close the cold inlet above the heater and cut its gas or breaker before you call.
When this becomes an emergency
- A damp ring or rust stain on the floor under the tank.
- Knocking or popping sounds while the heater is running.
- Hot water that has slowly become less hot over a season.
- The relief valve line dripping on its own.
What a pro does
A repair call sorts quickly into parts or replacement, and where the water is coming from decides it. Fittings, the drain valve and the relief valve are all serviceable. Water seeping from the shell itself means the steel has corroded through and the tank is at the end of its life. Where nothing is leaking, the plumber works through the controls: elements and thermostats on electric, thermocouple and gas valve and venting on gas. Two things wear heaters out faster than average in central Arkansas. Hard groundwater on well properties leaves a mineral bed across the bottom of the tank, so the burner heats through rock and runs longer than it should, which is what makes the popping noise people call about. The other is thermal expansion. Where a check valve or a pressure-reducing valve on the incoming supply gives heated water nowhere to expand into, pressure spikes each time the burner fires and the relief valve keeps letting go. That's a system problem showing up at the heater, and swapping the valve without addressing it just repeats the fault. Flushing sediment and checking the anode are what actually extend a tank's life.
