Tankless Units in Rowlett Homes
Most Rowlett 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 Rowlett
- Freeze damage. Freeze protection keeps the inside of a unit safe, not the exposed pipes under it. Uninsulated lines are where winter damage usually starts.
- Retrofit installs. Plenty of units here were fitted into older homes after the fact, and an undersized gas line or a long vent run can cause ignition faults years later.

The list below covers what we find on most visits for tankless water heater repair in Rowlett, TX, 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.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.
Hot, then cold, then hot
A short cold burst after the tap reopens is normal start-up. Swings during one shower point to low flow, scale or a failing flow sensor.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.

Fix It or Retire It? Deciding in Rowlett
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.
Read the model and serial off the label and call (380) 273-8196. The age and the fault together usually settle repair versus replace on the phone.
