In Puyallup, 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 Puyallup
- Garage installs. Many units here are mounted on a garage wall, which keeps them reachable for service and out of the worst weather.

A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.

Drip from the cabinet

Tankless Water Heater Repair in Puyallup, WA: FAQs

Question not covered here?

Call (380) 273-8196How much does tankless water heater repair in Puyallup, WA cost?
Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. Freeze repairs depend on what split, and are priced once the damage is seen.
How often should a tankless water heater be flushed?
Most makers call for a flush every year, and every six months on very hard water. On very soft water the gap can be longer, but skipping it for years invites scale faults.
Why is my tankless water heater not turning on?
Check for power at the outlet and that the gas valve is open. Beyond that it is usually low flow, a clogged inlet filter, a failed flow sensor or an ignition fault.
Why does my tankless water heater go hot then cold?
A second or two of cold after the tap reopens is normal start-up. If the water swings while it runs, look at low flow, scale or the flow sensor.
