Annual Water Heater Maintenance Checklist for Texas Homes
A short annual checklist catches most problems before they turn into a no hot water emergency. Here is what we recommend, adjusted for San Antonio and Houston conditions specifically.
| Task | San Antonio Schedule | Houston Schedule |
|---|---|---|
| Tank flush | Every 6 to 12 months | Annually |
| Tankless descale | Every 6 months | Annually |
| Anode rod check | Annually | Annually |
| Pressure relief valve test | Annually | Annually |
| Pre-season check | Not typically needed | Before hurricane season and hard freezes |
What to Look and Listen For Between Visits
- Popping or rumbling sounds during heating cycles
- Any moisture around the base of the tank
- Water temperature that feels inconsistent
- A rotten egg smell in hot water only
Why We Adjust the Schedule by City
San Antonio’s water hardness accelerates sediment and scale buildup, which is why we shorten flush and descale intervals here. Houston’s moderate hardness means standard annual maintenance usually covers it, but the added step of a pre-storm and pre-freeze check matters more given the weather risks specific to this city.
