Safety Precautions

Before you begin, it’s important to take the following safety precautions:

• Turn off the water supply to your water heater.
• Allow the water heater to cool down completely.
• Wear safety gloves to protect your hands.
• Have a bucket or drain pan ready to catch any water that may leak out.

Tools and Materials You’ll Need

• Adjustable wrench
• Phillips head screwdriver
• New plastic drain valve
• Teflon tape
• Pipe dope (optional)

Step-by-Step Instructions

1. Locate the Drain Valve

The drain valve is typically located at the bottom of the water heater tank. It is a small, plastic valve with a handle or knob.

2. Close the Drain Valve

If the drain valve is open, close it by turning the handle or knob clockwise.

3. Disconnect the Water Line

Use the adjustable wrench to disconnect the water line from the drain valve. Be careful not to overtighten the wrench.

4. Remove the Screws

Use the Phillips head screwdriver to remove the screws that hold the drain valve in place. There are typically two or three screws.

5. Carefully Remove the Drain Valve

Once the screws are removed, carefully pull the drain valve out of the water heater tank. Be prepared for some water to leak out.

6. Clean the Opening

Use a rag or brush to clean the opening where the drain valve was located. Remove any old sealant or debris.

7. Apply Teflon Tape and Pipe Dope (Optional)

Wrap Teflon tape around the threads of the new drain valve. You can also apply a small amount of pipe dope to the threads for added sealing.

8. Install the New Drain Valve

Insert the new drain valve into the opening and hand-tighten it. Use the adjustable wrench to tighten the valve further, but be careful not to overtighten it.

9. Reconnect the Water Line

Reconnect the water line to the drain valve and hand-tighten it. Use the adjustable wrench to tighten the connection further.

10. Turn on the Water Supply

Turn on the water supply to your water heater and check for any leaks. If you notice any leaks, tighten the connections further.
