Don't Ignor Your Water Heater

By Service Rank USA Team

Your water heater is the unsung hero of your home, working 24/7 to provide hot showers and clean dishes. But it is also a ticking time bomb. If the tank rusts through, it can flood your home with 50 gallons of water in minutes. Regular maintenance is key.

1. Flushing the Tank (Annually)

Sediment—minerals like calcium and lime from your water—settles at the bottom of the heater. Over time, this layer of "sand" hardens.
The Risk: The burner (gas) or element (electric) has to heat through this sediment layer to heat the water, causing overheating and eventual tank failure.
The Fix: Hook a garden hose to the drain valve at the bottom and let it run until the water is clear.

2. The Anode Rod (Every 3-5 Years)

This is a "sacrificial" metal rod inside the tank designed to attract corrosion so the tank walls don't rust. Once the rod is eaten away, the rust attacks the tank. Replacing a $40 anode rod can double the life of your heater.

3. Temperature Setting

Set your thermostat to 120°F (49°C).
Higher settings (140°F+) pose a scalding risk to children and increase mineral buildup.
Lower settings encourages bacteria growth (Legionella).

Signs of Failure

  • Rusty water coming from the hot tap only.
  • Rumbling or popping noises (sediment boiling).
  • Moisture around the base of the tank.

Time for a Tune-Up?

Professional plumbers can flush your tank and check your anode rod.
