Replacing a Jandy check valve is a relatively simple task that can be completed in a few hours with the right tools and materials. Follow these step-by-step instructions to ensure a successful replacement.
Tools and Materials You’ll Need:
- Adjustable wrench
- Pipe wrench
- Teflon tape
- Replacement Jandy check valve
- Plumber’s putty (optional)
Step 1: Safety First
Before beginning, turn off the water supply to the pool and ensure that the filter pump is not running.
Step 2: Locate the Check Valve
The Jandy check valve is typically located in the plumbing line between the filter and the pool. It is a small, cylindrical device with a single inlet and outlet.
Step 3: Disconnect the Check Valve
Using an adjustable wrench, loosen the nuts connecting the check valve to the plumbing lines. Be careful not to overtighten or damage the threads.
Step 4: Remove the Check Valve
Once the nuts are loosened, gently pull the check valve straight out of the plumbing line. If it is stuck, you can use a pipe wrench to carefully loosen it.
Step 5: Inspect the Check Valve
Examine the old check valve for any signs of damage or wear. If the valve is cracked, leaking, or has excessive debris, it should be replaced.
Step 6: Install the New Check Valve
Apply a thin layer of Teflon tape around the threads of the new check valve. This will help prevent leaks. Carefully insert the new check valve into the plumbing line and hand-tighten the nuts.
Step 7: Tighten the Nuts
Using an adjustable wrench, tighten the nuts connecting the check valve to the plumbing lines. Ensure that they are snug but not overtightened.
Step 8: Optional: Seal with Plumber’s Putty
If desired, you can apply a small amount of plumber’s putty around the base of the check valve where it meets the plumbing line. This will help prevent any potential leaks.
Step 9: Turn on the Water Supply
Once the check valve is replaced, turn on the water supply to the pool and check for leaks. If there are any leaks, tighten the nuts further or add more plumber’s putty.
Troubleshooting Tips
- If the check valve is leaking, it may be due to a faulty valve or improper installation. Check the valve for damage and ensure that it is installed correctly.
- If the check valve is stuck, it may be due to calcium buildup or other debris. Soak the valve in vinegar or a commercial descaler to dissolve the buildup.
- If you are unsure about replacing the check valve yourself, it is recommended to contact a qualified pool professional.
