Replacing a Navien check valve is a straightforward task that can ensure optimal water flow and prevent backflow issues in your plumbing system. This step-by-step guide will provide you with comprehensive instructions on how to replace the check valve effectively.
Materials You’ll Need
- New Navien check valve (compatible with your water heater model)
- Adjustable wrench
- Teflon tape
- Rags or towels
Safety Precautions
Before starting any work, ensure that the water supply to your water heater is turned off. Open a faucet downstream to release any remaining water pressure.
Step 1: Locate the Check Valve
The check valve is typically located on the cold water inlet pipe of your Navien water heater. It’s a small brass or plastic component with an arrow indicating the direction of water flow.
Step 2: Remove the Old Check Valve
Using an adjustable wrench, carefully loosen the nuts connecting the check valve to the water pipes. Remove the old check valve by gently pulling it off the pipe.
Step 3: Clean the Pipe Threads
Use a rag to clean any debris or old Teflon tape from the pipe threads where the check valve was connected. This will ensure a proper seal for the new check valve.
Step 4: Apply Teflon Tape
Wrap a few layers of Teflon tape clockwise around the threads of the new check valve. This will help create a watertight seal.
Step 5: Install the New Check Valve
Align the arrow on the check valve with the direction of water flow. Screw the check valve onto the cold water inlet pipe by hand as far as possible.
Step 6: Tighten the Check Valve
Use the adjustable wrench to tighten the check valve securely. However, avoid overtightening, as it can damage the valve.
Step 7: Turn on the Water Supply
Turn the water supply back on and check for any leaks around the check valve. If there are no leaks, you have successfully replaced the Navien check valve.
Troubleshooting Tips
- If you experience water leaking from the check valve, try tightening it further.
- If the check valve is still leaking, inspect the valve for any damage or debris.
- If you are unable to replace the check valve yourself, contact a licensed plumber for assistance.
