Water heater replacement for Austin homes
Most replacements are like-for-like: same fuel, same size, same spot. It's also the moment to check whether the old install was correct, because venting, gas line and expansion tank problems are common in older basements.

Water heater replacement in Austin: what's different
Austin's hard water causes mineral buildup in water heaters. Many homes have heaters in attics or garages.
Permits come from the City of Austin Development Services Department.
Heaters in attics need a drain pan and a working drain line, and many older installs lack one. Replacement is also a good time to add an expansion tank and consider a softener, since hard water shortens tank life. Tankless units are common in newer subdivisions but need annual descaling and often a larger gas line. Central Austin homes may need venting updates when the heater is replaced, and permits cover the inspection of venting, gas and relief valve.

No hot water? What to check first
On a gas water heater, check that the pilot is lit and the gas valve is on. On an electric heater, check the breaker and the high-limit reset button. If the pilot won't stay lit, the breaker trips again, or you smell gas, stop and call a plumber.

Repair or replace your water heater?
Repair when a replaceable part failed on a heater under about 8 years old. Replace when the tank itself leaks, the heater is past 10 to 12 years, or repairs keep adding up. A leaking tank can't be repaired.
