Why Should You Flush Water Heater?
Draining and flushing heater tank on a regular basis prevent debris, sediments, and minerals from depositing on the walls and at the bottom of the water heater tank. These sediment buildups affect the quality of water and make it harmful to consume. You may obtain colored, smelly water from it because of the sediments. The water heater may heat up too much or take too long to reheat the water because of these mineral deposits. Flushing eliminates these problems and helps increase the efficiency and lifespan of the water heater. If you don’t drain and flush your water heater for years, your water heater will spring a leak.

- Connect a garden hose to the drain valve located at the bottom of the water heater tank.
- Keep a big bucket handy to collect the drained water or extend the hose to a place where you can discharge water.

How Often Should You Flush Water Heater?
The need for flushing your water heater depends on the water quality, your region, size of the water heater tank, and the number of members in your house. If you have 1-3 people in your family, flush your water heater every 12-15 months. If you have 5 or more family members, consider flushing the tank every 6-8 months. Also, the harder the water in your area, the more likely you’ll need a more frequent tank flush.
