Top 3 Essential Maintenance Tasks from a Trusted Plumbing Company For Water Heaters

Whether you’re scheduling annual service or need a same day water heater replacement in the San Francisco Bay Area or Greater Los Angeles, CA, we are licensed water heater plumbers who are here to help.

1. Annual Flushing / Draining Your Water Heater

Flushing your water heater once a year helps prevent sediment from collecting at the bottom of the tank. Sediment buildup can reduce your water heater’s efficiency and shorten its lifespan.

Here’s why flushing matters:

  • Removes built-up minerals and debris
  • Helps your unit heat water faster and use less energy
  • Reduces the risk of overheating or tank failure

If your home has hard water, consider flushing every 6 months. Even “self-cleaning” models benefit from occasional draining—those systems help, but don’t eliminate sediment entirely.

2. Water Heater Inspections

Routine inspections can catch small issues before they become big repairs. We recommend a quick visual check once a year—or anytime you suspect a problem.

Start at the top of the tank and work your way down:

For Gas Water Heaters:

  • Check that cold and hot water lines are dry and free of leaks
  • Inspect the overflow pipe connection for moisture
  • Look at the vent pipe—make sure it’s:
    • Free of corrosion or soot buildup
    • Properly connected to the draft hood
    • Clear of debris that could block exhaust
  • Verify earthquake straps are snug (required in California)
  • Examine the gas line for:
    • Kinks or damage
    • Any strong gas odor (if present, leave the home and call the gas company)
  • Look at the base of the tank for signs of rust, water pooling, or corrosion
  • Ensure the air intake vents aren’t blocked by dust or clutter

For Electric Water Heaters:

  • Check electrical wiring at the top of the unit
  • Inspect thermostat covers for damage
  • Look around the base for leaks or rust

Safety Reminder: Never store flammable items near your water heater—gas or electric.
