Tankless Units in Gig Harbor Homes
In Gig Harbor, units usually hang in the garage of a craftsman or newer house. The water is mostly soft, so faults tend to be parts, not scale.
What we run into in Gig Harbor
- Garage installs. Here the unit typically lives in the garage, so the inlet filter and the service valves are easy to get at when it needs attention.
- Freeze damage. A hard freeze can split the pipes feeding a unit. Its built-in freeze protection only works while the unit still has power and gas.

The list below covers what we find on most visits for tankless water heater repair in Gig Harbor, WA, from ignition codes to drips under the cabinet.

Unit won't light
A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.

Drip from the cabinet
Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.

Venting fault
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Can't tell which one you have? Read us the display and describe the water, and the likely fault comes back on the call.

Fix It or Retire It? Deciding in Gig Harbor
Igniters, flame rods, sensors, fans, gas valves and boards are worth replacing on almost any unit. The hard call is a leaking or cracked heat exchanger on an older unit, because that part can approach the price of new.
