The Importance of a Water Heater Flush

Did you know that for the best water heater efficiency and extended life, you should have maintenance performed 1-2 times per year, depending on your home’s water quality? If you didn’t know that fact, then you probably don’t know what that maintenance consists of, so we decided to outline and explain.

Maintaining your water heater means having an annual water heater flush performed. Because of gas and/or electrical connections, and scalding hot water temperature, it is recommended that you hire a professional to do the flush for you.

Why should I have this done 1-2 times per year?

The answer is simple. It is needed maintenance that will save you money on energy costs, allow for more available hot water usage and increase the longevity of your unit’s life. In addition, when flushing the water heater, the plumber should inspect the water heater unit in its entirety to make sure there aren't other parts needing maintenance or replacing. The Anode Rod, which is what prevents the tank of the water heater from rapidly corroding, is an important feature to have inspected during this water heater flush maintenance. 

What does draining or flushing my water heater accomplish?

Throughout the year, the water flowing through your water heater carries lime, calcium, dirt, gravel and other sediment along its path.  This sediment builds-up in the bottom of your water heater and can drift into recirculation lines (faucets, bathtubs, shower valves) or jam open check valves and then eventually burn out the pump. If sediment build up is continually ignored, you are risking the cost of major repairs and possible complete system failure. (Flooding usually accompanies system failure)

So how do I know when to schedule the water heater flush?

  • Do you hear loud gurgling noises coming from your water heater?
  • Have you just moved into a new or older home and have no idea if the previous owner ever had maintenance done on the water heater?
  • Has it been a year since your last water heater flush? - If you aren’t sure, give us a call and we can tell you the last time we were at your home.
  • Is your water quality very poor? – This may be a sign the sediment is building up.
  • Is your water pressure or heat low compared to other homes and places you visit?
