How-to Guide: Step-by-step Guide on Draining Different Types of Hot Water Heaters

Before we dive into the specifics of draining your hot water heater, let’s first discuss the different types of hot water heater systems. There are three basic types:

• Tankless hot water heaters
• Electric hot water heaters
• Gas hot water heaters

Here’s a step-by-step guide according to each type:

Tankless Hot Water Heaters

Unlike traditional hot water heaters that have a storage tank, tankless hot water heaters can provide hot water on demand. Draining a tankless hot water heater is a fairly simple process:

1. Turn off the power supply or gas valve to the unit.
2. Close the incoming water valve to the unit.
3. Attach a garden hose to the drain valve and run it to a drain or outside.
4. Open the drain valve and let the water flush out for several minutes or until it runs clear.
5. Disconnect the hose and close the drain valve.
6. Open the incoming water valve and turn the power or gas back on.

Electric Hot Water Heaters

Electric hot water heaters rely on heating elements to warm the water in the tank. Here’s how you can drain an electric hot water heater:

1. Turn off the power supply to the unit.
2. Close the incoming water valve to the unit.
3. Attach a garden hose to the drain valve at the bottom of the tank and run it to a drain or outside.
4. Open the pressure relief valve and then open the drain valve to empty the tank.
5. After the tank is empty, close the drain valve and pressure relief valve, then turn on the incoming water supply.
6. Allow the tank to fill and then turn on the power supply.

Gas Hot Water Heaters

Gas hot water heaters operate with a pilot light and a burner to heat the water. Here are the steps to drain a gas hot water heater:

1. Turn off the gas supply to the unit.
2. Close the incoming water valve to the unit.
3. Attach a garden hose to the drain valve at the bottom of the tank and run it to a drain or outside.
4. Open a hot water faucet in your home and leave it open while draining the tank. This will prevent a vacuum from forming.
5. Open the drain valve and allow the water to flow out.
6. After the tank is empty, close the drain valve and the hot water faucet, then turn on the incoming water supply.
7. Once the tank is full, turn on the gas supply and relight the pilot light.

To ensure your safety, follow these tips when handling your hot water heater:

• Wear gloves, goggles, and closed-toe shoes.
• Never come into contact with hot water or steam.
• If you have a gas-fueled hot water heater, make sure to turn off the gas before draining the tank.
