You have to take care of your water heater, but you don’t often think about the sediment that can build up inside. That’s why you need to flush it out regularly if you want to save money and avoid problems in the future.
Most water heater manufacturers recommend that you flush your tank at least once a year. This is especially important if you live in an area where the water is hard and sediment can form.
This sediment can reduce your water heater’s energy efficiency and even cause damage to the tank or clog your pipes.
Flushing your water heater is one of the best ways to extend its life and save you money. You can do it yourself or hire a plumber to do the job for you.
The average water heater lifespan is 8 to 12 years, but this can be extended with regular flushing maintenance.
Flush your tank every one to three years depending on the water source and model.
Water heaters use natural minerals to heat water, and those minerals can settle to the bottom of your tank if they’re not drained and flushed regularly. Sediment can also corrode your tank, which can lead to expensive repair costs and possibly a water leak or fire.
Whether you’re dealing with a gas, electric or tankless water heater, it’s important to drain and flush your water heater regularly to ensure its efficiency and longevity.
To flush your water heater, shut off the electricity or gas supply valve to your water heater (which is typically located at the top of the unit) and turn off the cold-water inlet. Then, connect a garden hose to the water heater’s drain valve.
With the hose attached to your water heater’s drain valve, begin to let the water flow out of the spigots. This will trick the heater into thinking that it needs to be running so it will allow you to drain out the water in your tank.
Once the water in the tank has drained out completely, open all of the hot water faucets in your house. This will make sure that the water in your tank drains out the pipes in your home and will stop any vacuums that may be forming in those pipes during this process.
After the tank has drained out, open the pressure relief valve to the water heater and release any air from the pipework before you turn it back on. During this process, your water heater’s thermostat will need to be set on the lowest setting so that it’s not heating any water during this procedure.
When you’re done draining out the water in your tank, place a bucket underneath your discharge spigot to catch any remaining water. If you don’t have a bucket, you can use a trash can to catch the remaining water.
