Dallas gas water heater repair: what you need to know

Gas water heater issues need a licensed plumber, full stop. Pilot light failures, thermocouple replacement, gas valve issues, venting problems, burner assembly repairs. Tank or tankless. We send licensed Texas plumbers, every call.

Gas water heater repair is one of those jobs where DIY is genuinely dangerous and also not legal in most Texas cities. Gas connections leak. Pilot tubes get clogged. Burner assemblies foul up. Vents back-draft and dump CO into the house. Any of those mishandled is fire, explosion, or carbon monoxide. The plumbers we dispatch are TX licensed master plumbers with gas certifications, every call.

The good news: most gas water heater repairs are cheap parts and one-visit fixes. Thermocouples fail. Pilot tubes get dirty. Gas valves wear out. Flame sensors degrade. None of it is mystery if you've worked on gas before. The plumber rolls up with the common parts on the truck and you're back in hot water within the day.

If your gas water heater is past 12 years and starting to act up, replacement starts to make more sense than repair. Gas burner assemblies don't last forever, and once they're going, the next failure is usually close behind. The plumber will tell you straight whether you're in repair or replace territory.

Don't wait. Talk to a plumber now.

Is your water heater showing these signs?

Gas water heater issues all sound similar to homeowners but track to specific parts for the plumber. Here's the diagnostic shortlist.

  • Pilot light won't stay lit

    9 times out of 10 it's a bad thermocouple. Cheap part, one-visit fix. The other 10% is a dirty pilot tube or weak thermopile.

  • Pilot light won't ignite at all

    Could be the gas valve, the igniter, the thermocouple, or no gas to the unit. The plumber works through it in 15 minutes.

  • No hot water but pilot is lit

    Gas valve, thermostat, or burner assembly. Diagnostic by gas pressure test, then the part swap.

  • Gas smell near the unit

    Get out of the house and call. Do not flip switches or start cars. This is not a wait-for-tomorrow situation.

  • Yellow or sooty flames at the burner

    Combustion problem. Could be venting, gas pressure, or a burner assembly fouled with dust and lint. Carbon monoxide risk if it persists.

  • Soot or scorch marks on the unit

    Back-drafting or combustion issue. Could be a vent obstruction or a depressurized house pulling exhaust back inside. Don't ignore. Call.

  • Unit won't stay running, cycles on and off

    Often a flame sensor or thermopile not detecting the flame correctly. The plumber tests the millivolt output, swaps the part if needed.

See any of these? Don't wait.

Whatever you've got, we handle it

The plumber works on every common setup. If yours isn't listed, call. Chances are they handle it too.

  • Tank Gas Water Heaters

    Standard residential 30 to 80-gallon natural gas or propane tanks. Pilot, thermocouple, gas valve, burner, vent. Most common gas repair.

  • Tankless Gas Water Heaters

    Rinnai, Navien, Rheem, Noritz. Error codes, ignition, gas pressure, scaling. Tankless gas requires a plumber who knows tankless specifically.

  • Power-Vent Gas Units

    Sealed combustion units with a fan-assisted vent. Common in newer DFW construction or interior installs. Fan motor and combustion chamber issues most common.

  • Direct-Vent and Atmospheric

    Older atmospheric vents or sealed direct-vent units. Vent integrity, draft, and back-draft are the things to check first.

Gas Water Heater Repair: common questions

Quick answers about service from Water Heater Pros DFW.

How long do water heaters last in DFW?

Tank water heaters last 8 to 12 years. Tankless go 15 to 20 if you flush them every year. DFW's hard water knocks 1 to 3 years off either if the unit never gets serviced. If yours is past 10 and acting up, you're better off replacing it than throwing money at repairs.

Should I repair or replace my water heater?

Under 10 years old, one failed part? Repair it. Past 10 years with the tank itself leaking, multiple repair calls, or your gas bill creeping up? Replace it. The plumber on the call will tell you straight which side you're on.

Why is my water heater making noise?

Popping or rumbling? That's sediment trapped under the heating element, flashing to steam. Real common in DFW because of the hard water. A flush usually clears it. If the noise comes with rusty water or shorter showers, the tank's probably done.

Why don't I have any hot water?

Gas unit? Probably a pilot light, thermocouple, or gas valve. Electric? Check the breaker first, then the heating element. Either way a licensed plumber can tell you in 30 minutes. Most fixes are done the same visit.

Why does my hot water smell like rotten eggs?

Sulfur bacteria reacting with the magnesium anode rod inside your tank. Swap the anode for an aluminum/zinc one and the smell usually goes away. If the cold water smells too, the problem is your water supply, not the heater.

Why is my T&P (temperature & pressure) valve leaking?

A T&P valve that drips usually means high water pressure or thermal expansion. The fix is normally an expansion tank. Leaking hard and constant? Don't touch it. That valve is the only thing keeping your tank from blowing up. Call a plumber today.

What size water heater do I need for my DFW home?

Rule of thumb: 40-gallon tank for 1 to 3 people, 50 for 3 to 4, 65 to 80 for 5 or more. Tankless is sized by gallons-per-minute, not gallons stored. The plumber will size yours based on your bathrooms, fixtures, and water temperature coming in.

How does DFW's hard water affect water heaters?

DFW water is loaded with calcium and magnesium. That stuff settles at the bottom of tank heaters and crusts up the heat exchangers in tankless units. Result: less efficiency, more popping, shorter lifespan. Flush your tank once a year. Descale your tankless once a year. Both add years.

Can I install a water heater myself?

Don't. Texas requires a licensed plumber for water heater installs, and most DFW cities require a pulled permit too. DIY voids your home insurance and fails inspection at resale. For gas units it's genuinely dangerous. The few hundred bucks you save isn't worth the risk.
