A water heater is one of the most essential appliances in any rental property. When it fails, you'll have unhappy tenants and an expensive emergency repair. Regular maintenance can extend its life from 8-12 years to 15+ years.

How Often Should You Maintain a Water Heater?

Monthly Tasks

  • Check for leaks around the base
  • Listen for unusual sounds (popping, rumbling)
  • Verify pilot light is blue (gas heaters)
  • Check temperature setting (120°F recommended)

Every 6 Months

  • Test the pressure relief valve
  • Inspect visible pipes for corrosion
  • Check for water discoloration

Annually

  • Flush the tank to remove sediment
  • Inspect the anode rod (replace if corroded)
  • Check gas connections (gas heaters)
  • Inspect venting system

Every 3-5 Years

  • Replace anode rod (extends tank life significantly)
  • Professional inspection recommended

How to Flush a Water Heater

Sediment buildup reduces efficiency and can cause tank failure. Here's how to flush:

1. Turn off power/gas to the heater

2. Connect a hose to the drain valve

3. Turn off cold water inlet

4. Open the pressure relief valve

5. Open drain valve and let water flow

6. Flush until water runs clear

7. Close drain, refill tank, restore power

Time required: 30-45 minutes

Cost if DIY: Free

Cost if professional: $100-150

Signs Your Water Heater Needs Attention

  • Rusty water - Anode rod may be depleted
  • Popping sounds - Sediment buildup
  • Lukewarm water - Heating element issues
  • Leaks around base - Tank corrosion (may need replacement)
