Introduction
Every home has a hot water heater, but few homeowners know how to properly maintain it. Draining your hot water heater is an important task that should be done regularly. Over time, sediment and minerals build up in the tank, decreasing its efficiency and lifespan. Draining the tank can remove these deposits and keep your water heater running efficiently for years to come. In this article, we will walk you through the step-by-step process of draining your hot water heater, as well as provide tips for troubleshooting, safety precautions, and best practices.
Step-by-Step Guide
Step 1: Turn off the power or gas supply
Before you begin draining your hot water heater, you must first turn off the power or gas supply. This is an important safety precaution that must not be overlooked. If you have an electric water heater, turn off the power at the circuit breaker. If you have a gas water heater, turn off the gas supply using the valve near the unit.
Step 2: Attach a hose to the drain valve
Next, you will need to attach a hose to the drain valve on the bottom of the tank. The drain valve is usually located near the bottom of the front side of the tank. You will want to use a heavy-duty garden hose to ensure it can withstand the hot water and any sediment.
Step 3: Open the pressure relief valve and drain valve
Open the pressure relief valve and then the drain valve. The pressure relief valve is typically located at the top of the tank, while the drain valve is located at the bottom. By opening both of these valves, the water inside the tank will begin to flow out through the hose you attached in step 2. You can open the pressure relief valve by pulling up or flipping the lever. You will want to make sure that the hose is pointed towards a safe drain or outside, so you don’t accidentally flood your basement or home.
Step 4: Wait for the tank to drain
The time it takes for the tank to drain will vary depending on the size of your tank and the amount of sediment build-up. A typical 40-gallon tank may take up to 30 minutes to drain completely. During this time, you can use a brush or other tool to break up any sediment that may have settled on the bottom of the tank.
Step 5: Close the valves and refill the tank
Once the tank has been drained, close the drain valve and pressure relief valve. Then, remove the hose from the drain valve and turn the water supply valve back on. This will refill the tank. It’s important to leave a hot water faucet on until the tank is full to ensure that all the air is purged from the lines. Once the tank is full, turn the power or gas supply back on and allow the tank to heat up.
Troubleshooting
While draining your hot water heater is a straightforward process, there are a few issues that can arise. Below are some common troubleshooting solutions:
How to deal with leaks or clogs
If you encounter a leak or clog while draining your hot water heater, stop the process immediately and seek professional help. Leaks or clogs can lead to serious damage and require immediate attention.

Most hot water heaters have a lifespan of 10-15 years. If your unit is reaching this age or is experiencing frequent problems, it may be time to consider replacing it. Consult with a plumbing professional for advice on the best replacement options.
