Tankless Units in Bastrop Homes
Most Bastrop homes are brick houses where the tankless sits in the garage or on an outside wall. The February 2021 freeze showed how fast exposed lines can split here.
What we run into in Bastrop
- 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.
- Retrofit installs. Retrofits are common in this housing stock. When a unit throws flame codes only while the furnace or dryer runs, the gas supply is the first suspect.

When people phone about tankless water heater repair in Bastrop, TX, it is nearly always one of these problems. Each has a short list of causes.

Unit won't light
No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.

Water under the unit
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.

Code 10 or E110
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.
