Unclog your navien water heater instantly with this simple trick!

If you’re experiencing issues with your Navien water heater, such as excessive pressure or water leakage, you may need to open the pressure relief valve. This valve is designed to release excess pressure from the water heater to prevent damage. Opening the pressure relief valve is a simple task that can be performed by most homeowners. In this comprehensive guide, we’ll provide step-by-step instructions on how to open a Navien pressure relief valve, troubleshooting tips, and safety precautions to ensure a safe and effective process.

Understanding the Pressure Relief Valve

The pressure relief valve is a safety device located on the top of the water heater. It consists of a lever or handle that can be manually lifted to release pressure. The valve is designed to open automatically when the water pressure inside the tank exceeds a certain level, typically around 150 psi.

Safety Precautions

Before proceeding, it’s crucial to take the following safety precautions:

1. Turn off the water supply to the water heater.
2. Allow the water heater to cool down for at least 30 minutes before touching any components.
3. Wear gloves and safety glasses to protect yourself from hot water or debris.
4. Have a bucket or container nearby to collect any water that may be released.

Step-by-Step Instructions: How to Open Navien Pressure Relief Valve

1. Locate the Pressure Relief Valve

The pressure relief valve is typically located on the top of the water heater, near the cold water inlet. It will have a lever or handle that can be lifted.

2. Lift the Lever

Once you’ve located the pressure relief valve, gently lift the lever or handle. You should hear a release of water pressure. Allow the water to flow out until it stops or until the pressure gauge on the water heater drops to a safe level (around 80-100 psi).

3. Close the Valve

Once the pressure has been released, slowly lower the lever or handle to close the valve. Ensure that the valve is fully closed to prevent any further water leakage.

Troubleshooting Tips

If you encounter any issues while opening the pressure relief valve, try the following:

1. Valve Won’t Open: If the valve lever or handle is stuck, gently tap it with a hammer or wrench to loosen it.
2. Excessive Water Flow: If the water flow is too strong or doesn’t stop, the valve may need to be replaced. Contact a qualified plumber for assistance.
3. No Water Flow: If there’s no water flow when you lift the lever, the valve may be clogged. Try removing any debris or sediment from the valve opening.

When to Open the Pressure Relief Valve

In addition to releasing excess pressure, there are several other instances when you may need to open the pressure relief valve:

1. After Installing a New Water Heater: To remove any air from the system.
2. After a Power Outage: To reset the temperature and pressure settings.
3. During Seasonal Maintenance: To inspect and clean the valve.

Maintenance and Inspection

To ensure the proper functioning of the pressure relief valve, it’s essential to perform regular maintenance and inspection.

1. Monthly Inspection: Check for any leaks or damage to the valve.
2. Annual Cleaning: Remove any debris or sediment from the valve opening and lever.
3. Replacement: Replace the valve every 5-7 years or as recommended by the manufacturer.

Wrapping Up: Ensuring a Safe and Functioning Water Heater

By following these instructions and safety precautions, you can safely and effectively open the pressure relief valve on your Navien water heater. Remember to perform regular maintenance and inspection to ensure the longevity and reliability of your water heating system. If you encounter any difficulties or have concerns, don’t hesitate to contact a qualified plumber for assistance.
