DIY Water Heater Flush: Step-by-Step Guide

If you’re up for the challenge of flushing your water heater on your own, I’ve got you covered. Here is a step-by-step guide for conducting a successful water heater flush:

  1. First, turn off the power supply to your water heater. This can usually be done by switching off the circuit breaker or thermostat. If you have a gas water heater, turn off the gas supply valve.

  4. Open the pressure relief valve and the drain valve on your water heater. This will allow the hot water and sediment to drain out of the tank. Be careful as the water may be hot, and sediment can clog up the hose or drain.
  5. Wait for the tank to drain completely. Depending on the size of the tank and the amount of sediment, this can take anywhere from 20 minutes to an hour.
  6. Close the drain valve and remove the hose from the valve. Turn on the cold water supply valve to the water heater and allow the tank to fill completely. While the tank is filling, keep the pressure relief valve open to release any air pockets.
  7. Once the tank is full, turn the power supply to the water heater back on. If you have a gas water heater, relight the pilot light and turn the gas supply valve back on.
  8. Check the entire system for any leaks, unusual noises, or malfunctioning parts. If everything seems to be in order, you’re done!

Performing a DIY water heater flush should be done at least once a year to ensure its optimal performance. Now that you know how to flush a water heater, you can save money by doing it yourself and avoid potential breakdowns and costly repairs.
