No hot water is the call we get most often after drains, and it’s one where a fast, honest diagnosis matters: the difference between a failed thermostat and a failed tank is the difference between a repair today and a replacement conversation. JB Plumbing repairs tank and tankless water heaters, gas and electric, for homes and businesses across Austin and Travis County — 24 hours a day.
No hot water at all (failed heating element, thermostat, thermocouple or gas valve). Not enough hot water, or water that goes cold fast (a failed lower element, a broken dip tube, or a tank half full of sediment). Water that’s too hot or fluctuates (thermostat or mixing valve). Popping, rumbling or banging (sediment boiling under the burner — an Austin classic). Rusty or discolored hot water (a spent anode rod, or a tank corroding from the inside). A pilot that won’t stay lit. A pressure-relief valve that drips. A tankless unit throwing error codes or dropping its flow.
A leak from the tank body itself can’t be repaired — that’s a replacement. A younger unit with a failed part is usually worth fixing. In between, we weigh the unit’s age, its condition, and how it’s been affected by Austin’s hard water, and we give you both numbers so the decision is yours. Our guide “Water Heater: Repair or Replace?” walks through the same logic.
Central Texas water carries a lot of dissolved minerals. Over time they settle in the bottom of a tank, insulate the burner from the water, and cook the tank from beneath — which is why heaters here often fail earlier than the manufacturer’s number suggests. An annual flush and a fresh anode rod are the cheapest years you can add to a heater’s life, and we can do both while we’re there.
We answer 24/7, most calls are returned within the hour, and estimates are free on most services. Call (512) 663-3049 and tell us what the heater is doing — we’ll tell you what to switch off while you wait.

On an electric heater it’s usually a failed element or thermostat, or a tripped breaker; on gas, a pilot or thermocouple problem or a failed gas valve. On a tankless unit, an error code or scale in the heat exchanger. Check the breaker or pilot first; if that isn’t it, call and we’ll diagnose it properly.
That’s sediment from Austin’s hard water boiling under the burner or element. It makes the heater work harder and shortens its life. A flush usually fixes it — if the sediment has been there for years, we’ll tell you honestly how much life is left.
A tank leaking from its body can’t be repaired. A younger heater with a failed part is usually worth fixing. Between those, we look at age, condition and hard-water wear and give you both prices — the choice is yours.
Yes — error codes, flow problems, ignition faults and descaling. Tankless units in hard-water areas need periodic descaling to keep working; we can set you up with a schedule.
Yes. Close the cold-water valve on top of the unit, switch off its power or gas, and call. We’re open 24 hours.
