Installing an above ground pool return fitting might seem daunting at first, but with the right guidance, it's a task that's well within the reach of the average homeowner. This fitting is crucial for maintaining proper water circulation and ensuring the longevity of your pool's filtration system. In this comprehensive guide, we'll walk you through the process step by step, ensuring you have all the information you need for a successful installation.
Understanding Your Above Ground Pool Return Fitting
Before we dive into the installation process, let's first understand what a return fitting is and why it's important. A return fitting, also known as a return jet or return line, is a component of your pool's plumbing system that directs water back into the pool after it has been filtered. This not only helps to circulate the water, preventing stagnation and algae growth, but also creates a pleasant swimming experience by creating a gentle, soothing flow.
Tools and Materials Needed
Before you begin, ensure you have all the necessary tools and materials on hand. You'll need:

- Your pool's return fitting (ensure it matches your pool's size and type)
- Teflon tape
- Adjustable wrench
- Pool plumbing line cutter (or a hacksaw)
- Tape measure
- Marker
- Silicone-based lubricant (optional, but helpful for a smooth installation)
Step-by-Step Installation Guide
Step 1: Locate the Return Line
First, you'll need to locate the return line in your pool's plumbing system. This is typically a 1.5-inch pipe that connects the filter to the pool. It's usually marked with a 'Return' label or a 'R' symbol.
Step 2: Measure and Mark the Installation Point
Using your tape measure, determine the best location for your return fitting. This is typically about 6 inches below the waterline and on the opposite side of the pool from the skimmer. Mark the spot with your marker.
Step 3: Cut the Plumbing Line
Using your pool plumbing line cutter or hacksaw, carefully cut the return line at the point you've marked. Be sure to wear safety glasses to protect your eyes from any debris.

Step 4: Prepare the Return Fitting
Remove the cap from the return fitting and wrap the threads with Teflon tape. This will help to create a watertight seal. Apply the tape in a clockwise direction, overlapping each layer by half. Apply a light coat of silicone-based lubricant to the threads for a smoother installation.
Step 5: Install the Return Fitting
Insert the return fitting into the hole you've cut in the return line. Using your adjustable wrench, tighten the fitting by turning it clockwise. Be careful not to overtighten, as this can cause the fitting to crack. The general rule of thumb is to tighten until the fitting is snug, then give it an additional quarter to half turn.
Step 6: Test the Installation
Once the fitting is securely in place, turn on your pool's pump. Water should flow out of the return fitting, creating a gentle current in your pool. If there are any leaks, you may need to tighten the fitting further or apply additional Teflon tape.
Troubleshooting Common Issues
| Issue | Possible Cause | Solution |
|---|---|---|
| Leaks around the return fitting | Inadequate Teflon tape or overtightening | Apply more Teflon tape and/or tighten the fitting slightly |
| No water flow from the return fitting | Blockage in the return line or pump issue | Check for blockages and ensure your pump is functioning properly |
Remember, if you're unsure about any aspect of the installation process, it's always best to consult with a professional. They can provide guidance tailored to your specific pool and ensure that everything is installed correctly and safely.
Installing an above ground pool return fitting might seem like a big task, but with the right knowledge and tools, it's a job that any homeowner can tackle. By following the steps outlined in this guide, you'll have your pool's water circulating smoothly in no time. Happy swimming!
