Tankless Units in La Marque Homes

Most La Marque 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 La Marque

  • Freeze damage. Cold snaps do damage here when the power drops overnight. A frozen line or a cracked fitting under the unit is a repair we see after every deep freeze.
  • Retrofit installs. In older homes converted to tankless, the original gas piping is not always big enough. Pressure gets measured with the burner at full fire before parts are blamed.

Common faults

Tankless Problems We Fix Around La Marque

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

Flame rod cleaned above the burner during tankless water heater repair in La Marque, TX

Code 11, E003 or 111

No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.

Drip at the service valves under the unit, traced during tankless water heater repair in La Marque, TX

Water under the unit

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

Intake and exhaust terminations cleared during tankless water heater repair in La Marque, TX

Code 10 or E110

Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.

Noisy or whistling

Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.

Error code keeps coming back

A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.

Shuts off mid-shower

Flow drops below what the unit needs to keep firing: a clogged filter, aerator or shower cartridge, or a sensor misreading.

La Marque Homes by the Numbers

8,060housing units
1978median year built
53%of homes heated by gas
71%owner-occupied

Gas heats about 53% of homes in La Marque and electricity about 45%, so both gas and electric tankless units turn up on calls here. Housing here is older (median year built 1978), and older homes were plumbed and vented for tank heaters, so tankless retrofits often meant new gas lines, venting or a condensate drain, which are common places for faults to start. Owners live in about 71% of La Marque homes (single-family about 86%), so the person who calls is usually the person who decides.

With about 18,833 residents on roughly 14 square miles (near 1,369 per square mile), La Marque is spread out, with mostly detached homes on larger lots and longer runs between fixtures and the street. It is number 107 by population of the 322 Texas places on our service list.

How much does tankless water heater repair in La Marque, TX 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.

Why is my tankless water heater not turning on?

First confirm power and gas. If both are there, the usual causes are low flow, a dirty inlet filter, a bad flow sensor or an ignition fault.

How often should a tankless water heater be flushed?

Once a year for most homes, and twice a year on very hard water. Soft-water homes can stretch it, but never skip it for years.

How long does a tankless water heater last?

Gas units commonly run 20 years or more when they are flushed on schedule. Electric tankless units tend to last closer to 7 to 10 years.
