When replacement makes sense
The tank is leaking
A leaking tank body cannot be repaired.
Age over about 10–12 years
Repairs on an aging tank often buy little time.
Hot water no longer keeps up
Household needs may have outgrown the heater.
Rust-colored hot water
A corroding tank interior.
Choosing a replacement
Tank (gas or electric)
Lowest upfront cost; 40–50 gallons suits many households.
Tankless
Endless hot water and a smaller footprint, but gas line and venting upgrades are common. See tankless water heaters.
Heat pump (hybrid)
Very efficient electric option; needs space and airflow.
Code items in Dallas installations
Expect the installer to address the temperature and pressure relief valve and discharge line, a drain pan where required, proper venting for gas units, sediment trap, secure mounting, and an expansion tank if the system is closed. Garage installations of gas units usually require elevation of the ignition source. A permit and inspection are generally required in Dallas.
Water heater replacement cost
Installed cost depends on type, size, fuel, location, and code upgrades. See the water heater replacement cost guide for sourced national ranges.
