Water heaters in Dallas, TX
Most tank water heaters last about 8 to 12 years. A plumber can often repair a heater that stops making hot water, but a tank that leaks from the bottom has failed and needs to be replaced. Tankless heaters last longer but cost more to install, especially if the gas line or venting has to change.

Water heater repair in Dallas
UrgentIf a gas water heater has no hot water, the pilot, thermocouple or gas valve is the usual cause; on an electric heater it's usually an element or thermostat. Those parts are repairable. A tank that leaks from the bottom can't be repaired and needs to be replaced.
Water heater replacement
A leaking tank or a heater past about 10 years old is usually replaced rather than repaired. A proper install includes a permit, correct venting (adjusted for altitude where needed), an expansion tank where required, a drip leg on the gas line and a relief valve discharge pipe.
Tankless water heaters
A tankless water heater heats water as it flows, so it doesn't run out, but it needs a larger gas line, its own venting and a unit rated for your elevation. Installed correctly and descaled regularly, it can outlast a tank heater.

Water heaters in Dallas: what's different
Mineral-heavy water in Dallas shortens water heater life and clogs tankless heat exchangers, so regular flushing and descaling matter. Many heaters are in attics or garages, which affects access and requires a drain pan.
Permits for water heater replacements come from the City of Dallas Development Services department, and the inspection checks venting, gas connections and the pressure relief valve.
After Winter Storm Uri, many Dallas homeowners also asked about heaters and lines in unconditioned attics. Insulating those lines, and the heater's supply pipes, reduces freeze risk during the next hard freeze.

Dallas housing and plumbing
Older areas like Lakewood, the M Streets and Oak Cliff have pre-war homes with cast-iron drains and some galvanized supply, while much of the metro is 1970s and later slab construction.
Other Dallas conditions that affect plumbing
- Clay soil and cast-iron drains: Soil movement and aging cast iron under slabs lead to cracked drains, which a camera inspection and hydrostatic test can confirm.
- Winter ice storms: North Texas gets occasional ice storms and hard freezes, and attic or exterior-wall pipes in heat-built homes are the first to burst.
- Hard water: Mineral-heavy water shortens water heater life and clogs aerators and tankless heat exchangers.
- Winter Storm Uri lessons: The February 2021 winter storm burst pipes across Dallas because many homes have plumbing in attics and exterior walls. Insulating attic lines, sealing gaps and knowing where the main shutoff is are now common requests before winter.
