Your Water Heater This Spring: One Important Task

With the coronavirus keeping us at home much more than usual right now, it’s more important than ever to keep your home comfort equipment working efficiently and reliably. One of the most important and often overlooked pieces of home comfort equipment in your Connecticut home is your water heater.

If you have a conventional water heater (one that has a storage tank), a key to keeping it running well is preventing sediment build-up. Sediment, which looks like sand or gravel, forms from minerals contained in your water supply; when it gathers at the bottom of your tank or on your water heater’s heating element, it can diminish energy efficiency and clog the tank’s drain valve, which can be a safety hazard.

The good news is that sediment build-up is easy to control with periodic flushing of your storage tank.

How To Flush Your Water Heater Storage Tank:

What you’ll need:


  1. Turn off the power to the water heater at the circuit breaker; if you have a propane gas water heater, you will also need to turn off the gas supply.
  2. Fasten a length of garden hose to the drain valve at the bottom of the water heater. If you can’t locate the drain value, consult your water heater’s owner’s manual.
  3. Run the other end of the hose to the nearest floor drain, or outside your house.
  4. Close the shut-off valve at the water inlet line or main water supply.
  5. Open a hot water faucet somewhere in the house to relieve system pressure inside the tank.
  6. Slide a knee-high stocking over the drain end of the garden hose to capture sediment and scale as the water heater drains; use the rubber band or wire tie to hold it in place. If you capture a lot of sediment, you’ll need to flush your water heater more often.
  7. Using your screwdriver, open the drain valve (the other side of the Y connector where you attached the hose). Use caution: the water that will flow into your floor drain or outside your home will be hot enough to scald.
  8. Drain about three to five gallons of water, which should be enough to capture the needed sediment.
  9. When you’re done, close the drain valve with your screwdriver and remove the hose.
  10. Open a hot water faucet somewhere in the home, then open the shut-off valve at the water inlet line or main water supply. You’ll hear the water heater start to fill. When you have a steady stream of water at the faucet, turn it off.
  11. Turn the power back on at the circuit breaker. For propane gas water heaters, turn the gas supply back on.

Of course, an occasional flush isn’t the only maintenance you’ll need for your water heater – you’ll also need professional water heater maintenance about every two years (which you can get as part of our Home Comfort Membership’s Water Heater Inspection Plan).
