Swimming pool return fittings are crucial components that help circulate water, keep your pool clean, and ensure even distribution of chemicals. Over time, these fittings may need to be removed for maintenance, replacement, or upgrades. This guide provides detailed instructions, visuals, and troubleshooting advice to make the process straightforward and stress-free.
Pool return fittings, often referred to as return jets or outlets, are located on the pool wall and are responsible for returning filtered water from the pump back into the pool. They typically consist of several parts:
- Eyeball: The directional nozzle that controls water flow.
- Lock Ring: Secures the eyeball in place.
- Inner Fitting: The threaded part inside the pool wall.
- Outer Assembly: The exterior part that seals the fitting to the pool wall.
These components work together to ensure the water in your pool is evenly circulated, which is essential for keeping the pool clean and maintaining proper chemical balance.

Before starting, gather the following tools and materials:
- Channel locks or adjustable pliers
- Needle-nose pliers
- Seat removal tool (specialized tool for some fittings)
- Flathead screwdriver
- Wood shim (to protect pool surfaces)
- Pool-safe silicone sealant (if reinstalling)
- Clean towel or rag
Having the right tools on hand will make the process much easier and help prevent accidental damage to your pool equipment.
Begin by lowering the water level in your pool below the return fitting. This prevents water from spilling out during removal and allows for easier access. Lowering the water also helps you see and reach the fitting more comfortably, reducing the risk of accidental spills or splashes.
1. Locate the Return Fitting: Find the return jet on the pool wall.
2. Turn the Lock Ring Counterclockwise: Use your hand or channel locks to loosen the lock ring securing the eyeball.
3. Remove the Eyeball: Once the lock ring is off, gently pull out the eyeball.
If the lock ring is difficult to turn by hand, use a rubber grip or a piece of cloth for better traction. Avoid using excessive force to prevent cracking the plastic components.
1. Identify the Notches: Look inside the fitting for two small notches.
2. Use Needle-Nose Pliers or Removal Tool: Insert the tips into the notches and turn counterclockwise to unscrew the inner fitting.
3. If Tight, Use a Seat Removal Tool: For stubborn fittings, a specialized seat removal tool can provide extra leverage.
Be patient during this step—forcing the fitting can strip the threads or damage the pool wall.
1. Go Outside the Pool Wall: Locate the outer part of the return fitting.
2. Loosen the Lock Nut: Use channel locks to turn the lock nut counterclockwise.
3. Remove Old Gaskets: Carefully remove any gaskets or seals.
4. Push Out the Assembly: Apply gentle inward pressure to the hose adapter or fitting to pop it out from the pool wall.
Inspect the removed parts for signs of wear, cracks, or deterioration. If any components are damaged, replace them before reinstalling.

Sometimes, fittings can become stuck due to age, cross-threading, or debris. Here are some solutions:
- Apply Penetrating Oil: Let it sit for a few minutes to loosen threads.
- Use a Flat Piece of Metal: Fit it into the notches for extra torque.
- Leverage with a Screwdriver: Carefully pry behind the flange, using a wood shim to protect the pool wall.
- Avoid Excessive Force: If plastic tools deform, consider a heavy-duty metal removal tool.
If a fitting remains stubborn after these attempts, consider consulting a pool professional to avoid damaging the pool structure.
- Always lower the water level before starting.
- Wear gloves to protect your hands from sharp edges.
- Use protective gear such as safety glasses when working with tools.
- Handle tools carefully to prevent damage to the pool liner or wall.
- Inspect and replace gaskets if they appear worn or cracked.
- Clean the area thoroughly before reinstalling any fittings.
- Store removed parts in a safe place to prevent loss or damage.
Once the return fitting is removed, take the opportunity to clean the area thoroughly. Remove any debris, algae, or buildup from the fitting opening and surrounding pool wall. If you notice any cracks or signs of wear on the pool wall or liner, address them before reinstalling or replacing the fitting.
- Use a soft brush or cloth to clean the area.
- Inspect the threads for damage or debris.
- Apply a small amount of pool-safe lubricant to the threads if reinstalling.
- Replace any worn or damaged gaskets to ensure a watertight seal.
Proper maintenance at this stage can extend the life of your pool equipment and reduce the risk of leaks.
It's important to know when a fitting can be repaired and when it should be replaced:
- Replace if: The fitting is cracked, warped, or shows signs of significant wear. Damaged fittings can cause leaks or circulation problems.
- Repair if: The fitting is simply stuck or has minor cosmetic damage. Often, cleaning and lubricating the threads or replacing the gasket is sufficient.
If you are unsure, consult your pool manufacturer's guidelines or speak with a pool professional for advice.
- Not Lowering the Water Level: Attempting to remove fittings with the water at normal level can lead to spills and make the job much harder.
- Using Excessive Force: Over-tightening or forcing tools can damage the fitting or pool wall.
- Skipping Gasket Replacement: Old or worn gaskets can lead to leaks. Always inspect and replace as needed.
- Ignoring Manufacturer Instructions: Different pools and fittings may have specific requirements. Always check the manual before starting.
- Improper Tool Use: Using the wrong tool can strip threads or crack plastic parts.
By avoiding these mistakes, you'll ensure a smoother, safer removal process.
Removing pool return fittings is a manageable task with the right tools, preparation, and knowledge. By following the outlined steps and safety tips, you can efficiently remove and replace fittings, ensuring your pool remains in top condition. Always refer to your pool's manufacturer guidelines for specific instructions, and don't hesitate to consult a professional for complex issues. With patience and care, you'll keep your pool running smoothly and extend the life of its components.

Lowering the water level below the return fitting prevents water from spilling out and allows you to work more comfortably and safely.
Use a seat removal tool or needle-nose pliers in the notches. For severe cases, apply penetrating oil and use a flat piece of metal for extra leverage. Avoid using excessive force to prevent damage.
Yes, channel locks, adjustable pliers, and needle-nose pliers are commonly used. For tight or specialized fittings, a seat removal tool is recommended.
Always use a wood shim or soft barrier when prying with a screwdriver. Work slowly and avoid sharp tools directly against the liner.
Removing the fitting allows for the installation of threaded plugs, which provide a watertight seal during winter. If you choose not to remove it, use a rubber expansion plug, but ensure it seals tightly to prevent leaks.
