How To Flush Your Tank: Basic Overview

To begin flushing your tank, start by turning off the tank and water supply.

Next, connect a hose to the tank’s drain valve for water discharge.

Open the drain, run hot water to release pressure, then turn on the water supply to flush the tank.

Step 1: Turn off the Tank and Water Supply

To properly flush your hot water heater tank, the initial step is to turn off the tank and water supply. This important step ensures safety and prevents accidental water flow during the flushing process. It also allows the tank to cool down and prevents hot water from escaping while you’re flushing it. Here’s why turning off the tank and water supply is essential:

  1. Ensures safety during the flushing procedure.

  2. Prevents accidental water flow that could disrupt the process.

  3. Allows the tank to cool down and avoids hot water discharge during flushing.
