Should You Drain or Flush Your Water Heater?

If you want to steer clear of hot water heater replacement and prolong the lifespan of your unit, it pays to conduct preventative maintenance. One of the most important tasks you shouldn’t skip is flushing and draining the tank at least once a year. Read on as Roberts Plumbing Hydro Jet & Rooter discusses how doing these can benefit you.


Heated water leaves mineral deposits that can accumulate in the tank over time. This sediment creates a barrier between the water and the unit’s heating elements, impairing its efficiency. They can also cause corrosion and pinhole leaks when left neglected for too long. Besides timely water heater repair in Northridge, CA, flushing the tank can help you get ahead of this issue.

Flushing removes the sediment buildup in the tank and refreshes your hot water supply. It works by connecting a hose to the drain valve. After turning on the valve, you can safely dispose of water from the tank. Keep the water supply open until the sediment is gone.


While draining won’t remove the sediment buildup, it allows you to check the tank for signs of damage. During water heater services, the water supply must be turned off. Then, as the water drains, check if it is smelly or discolored. If that is the case, your water heater might be nearing the end of its useful life, as leaks are likely to show up soon.
