Protect your investment by having your water heater serviced annually by a licensed plumber
The frequency with which to flush a water heater depends on the size of the tank and the amount of hot water used. It is a good idea to refer to the manufacturer’s instructions. Usually, the more hot water a household uses, the greater the maintenance flushing frequency.
With time, water heater sludge accumulates at the bottom of a tank as minerals, sediment and other deposits settle in the water. Flushing out these deposits prolongs the heater’s life and prevents malfunctions, such as cold burst of water.
One or two people in a home:
Inspect the water heater every six months and drain it every 12 months
Three to five people in a home:
Inspect the water heater every four months and drain it every eight months
Six or more people in a home:
Inspect the water heater every four months and drain it every six months
You may need to drain the hot water tank more often if your water comes from a well or if your municipal water has abnormally high sediment content.
