FAQs
How often should I schedule water heater maintenance?
In San Antonio, most homes do best with yearly water heater maintenance. Hard water can speed up mineral buildup, so some tanks benefit from a flush every 6 to 12 months. We will recommend a schedule based on your unit, usage, and water quality.
What does a water heater maintenance visit include?
A PlumbSmart maintenance visit includes safety checks, a performance check, and cleaning where needed. We inspect the thermostat, heating element or burner, venting or electrical connections, and the temperature and pressure relief valve. We also look for leaks, corrosion, and excess sediment.
Can hard water damage my San Antonio water heater?
Yes. San Antonio hard water can leave scale inside the tank and on heating parts. That buildup makes the heater work harder, which can raise energy costs and shorten its life. Regular flushing and inspections help reduce sediment, protect components, and keep recovery time fast.
Do tankless water heaters need maintenance in San Antonio?
Tankless units still need regular care, especially with hard water. We descale the system, clean filters, and confirm the unit is firing correctly and venting safely. Proper tankless water heater maintenance in San Antonio helps prevent error codes, low flow, and sudden temperature swings.
Is water heater maintenance cheaper than replacement in San Antonio?
Almost always. Maintenance costs far less than replacing a tank, fixing water damage, or missing work for an emergency. A simple tune-up can catch a failing anode rod, valve, or thermostat early. That keeps your San Antonio water heater running longer and more efficiently.
