Most water heaters do not fail overnight. They wear out from sediment, corrosion and neglected parts. A short routine each year catches problems while they are cheap to fix, and in much of Texas that routine matters more because of hard water.
Why Texas Water Heaters Need Regular Maintenance
Many Texas cities, including San Antonio and the Austin area, have hard water. Minerals settle at the bottom of a tank, insulate the heating surface and make the unit work harder. Tankless units scale up inside the heat exchanger. The result is higher bills, noise, slower recovery and a shorter life.
The Annual Checklist
- Test the temperature and pressure relief valve. Lift the lever briefly and confirm water flows and stops. Replace the valve if it sticks or drips.
- Flush the tank. Draining a few gallons removes loose sediment. See our guide to flushing a water heater in Texas.
- Check the anode rod. It protects the tank from corrosion and is often worth checking after a few years.
- Look for leaks and rust around fittings, the base and the drain valve.
- Check the thermostat setting. Around 120 degrees is a common safe setting.
- Inspect gas and venting if your unit is gas. This is a job for a licensed technician.
Tankless Maintenance
Tankless units need descaling on a schedule that depends on water hardness, plus cleaning of the inlet filter. If yours shows error codes or inconsistent temperature, read our guide to tankless water heater repair.
When to Call a Professional
Call a licensed pro for gas work, electrical work, a leaking tank, rumbling that does not clear after a flush, or any unit near the end of its life. For service in San Antonio, see water heater repair in San Antonio. Other cities are listed on our home page.
