What does water heater maintenance include?
Water heater maintenance includes flushing sediment from the tank, checking the anode rod, testing the relief valve, inspecting the gas burner or electric elements, checking venting and seismic straps, and setting a safe temperature. In Mission Viejo, yearly maintenance helps fight mineral buildup from moderately hard water.

- Check or replace the anode rod
- Test the T&P relief valve
- Inspect the burner, pilot and flue
- Test electric elements and thermostats
- Check seismic straps and gas lines
- Look for rust and slow leaks
- Set the temperature to about 120°F
How often should you flush a water heater in Mission Viejo?
Flush a tank water heater once a year in Mission Viejo. The moderately hard water supplied by local water districts leaves calcium and magnesium sediment at the bottom of the tank. If you hear popping or rumbling, it is time for a flush now. Tankless units need yearly descaling instead.
Sediment acts like a blanket between the burner and the water. The heater runs longer, costs more to operate and wears out sooner. A yearly flush keeps it efficient and quieter.
What is an anode rod and why does it matter?
An anode rod is a metal rod inside the tank that corrodes on purpose so the steel tank does not. Once the rod is used up, the tank starts to rust. Checking it every 2 to 3 years and replacing it when worn can add years to a water heater's life.
If your hot water smells like rotten eggs, the anode rod may be reacting with bacteria in the tank. A powered anode or an aluminum-zinc rod can fix the smell.

Can you flush a water heater yourself?
Yes, many homeowners can flush a tank water heater. Turn off the gas or power, close the cold water supply, attach a hose to the drain valve, open a hot tap and drain until the water runs clear. Old drain valves can break or leak, so if your tank is over 8 years old, have a pro do it.
- Turn the gas control to pilot or off, or switch off the breaker.
- Let the water cool for a few hours to avoid burns.
- Close the cold water supply valve.
- Connect a garden hose to the drain valve and run it outside.
- Open a hot water tap in the house, then open the drain valve.
- Drain until the water is clear, close the valve and refill before turning the heat back on.
Safety: Never turn an electric water heater on while the tank is empty. It will burn out the heating elements.
How can you make your water heater last longer?
Flush it yearly, check the anode rod every few years, keep the temperature near 120°F, add an expansion tank if your home has high pressure, and keep the area around the heater clear. A water softener also helps in Mission Viejo, where hard water shortens tank and tankless life.
- Set the thermostat to about 120°F to cut scale and scald risk
- Test the relief valve once a year
- Keep boxes and paint cans away from gas water heaters
- Make sure seismic straps are tight
- Consider a water softener or scale filter

Water Heater Maintenance & Flushing FAQs
What happens if you never flush a water heater?
Sediment builds up, the heater gets noisy, runs less efficiently and can overheat the tank bottom, which shortens its life.
How long does a water heater flush take?
About 30 to 60 minutes for most tanks, longer if there is heavy sediment.
Is it too late to flush an old water heater?
If a tank has never been flushed in 10 years, flushing can loosen sediment that was plugging small leaks. Have a pro check it first.
What temperature should my water heater be set to?
About 120°F is safe and efficient for most homes. Higher settings raise scald risk and scale buildup.
Do tankless water heaters need maintenance?
Yes. They need yearly descaling and inlet filter cleaning. See our tankless water heater page.
