How to Replace a Broken Pool Return Jet

A pool return jet plays a crucial role in maintaining water circulation by directing filtered water back into the pool. When a return jet breaks or malfunctions, it can disrupt water flow, leading to dead spots, poor filtration, and even algae growth. Fortunately, replacing a broken pool return jet is a straightforward process that most pool owners can handle on their own. Here’s a step-by-step guide to help you swap out your damaged jet with ease.

Signs That Your Pool Return Jet Needs Replacement

Before replacing the return jet, it’s important to recognize the signs that indicate it’s no longer functioning properly:

Weak or no water flow coming from the return jet.
Cracked or broken jet housing that affects water pressure.
Unusual water circulation patterns causing dead spots in the pool.
Difficulty adjusting the jet’s direction due to stuck or damaged components.
Visible wear and tear like cracks, discoloration, or broken threading.

If you notice any of these issues, it’s time to replace the return jet to restore proper pool circulation.

Tools and Materials Needed

Before starting the replacement process, gather the necessary tools and supplies:

Replacement pool return jet (matching the size and type of the old one)
Adjustable wrench or channel-lock pliers
Pool-safe Teflon tape (for sealing threads)
Pool pump wrench (if needed for tight fittings)
Soft cloth or sponge (for cleaning around the fitting)
Bucket (to catch excess water)

Having these items ready will make the process smoother and more efficient.

Step-by-Step Guide to Replacing a Broken Pool Return Jet

Step 1: Turn Off the Pool Pump

Before working on the return jet, ensure the pool pump is completely turned off. This prevents water from forcefully spraying out and eliminates the risk of damage to the filtration system.

Locate your pool’s pump and switch it off at the power source.
If necessary, close the skimmer and main drain valves to stop water flow.
Allow the pool water to settle before proceeding.

Step 2: Remove the Old Return Jet

Once the pump is off, remove the broken return jet:

Loosen the jet fitting using an adjustable wrench or channel-lock pliers.
Unscrew the jet faceplate counterclockwise by hand or with a wrench if it’s tight.
If the jet is stuck, use a rubber grip pad or apply light pressure with pliers.
Remove any remaining debris or pieces of the old jet from the fitting.

Step 3: Clean the Fitting Area

Before installing the new jet, clean the surrounding area:

Use a soft cloth or sponge to remove dirt, algae, or debris from the jet housing.
Inspect the threading inside the return line for damage.
If necessary, apply pool-safe Teflon tape around the threads to create a watertight seal.

Step 4: Install the New Pool Return Jet

Now that the fitting is clean, install the replacement jet:

Align the new return jet with the opening and insert it carefully.
Screw it in clockwise by hand until snug.
Use an adjustable wrench to gently tighten the jet, ensuring a secure but not overtightened fit.
Adjust the jet nozzle to direct water flow properly (typically angled slightly downward for optimal circulation).

Step 5: Turn the Pool Pump Back On

With the new return jet installed, it’s time to test it:

Open any closed valves to restore water flow.
Turn the pool pump back on at the power source.
Check for leaks or unusual water pressure issues.
Observe the water flow from the return jet and adjust the nozzle if necessary.

If everything looks good, your pool return jet replacement is complete!

Tips for Maintaining Your Pool Return Jets

To prevent future issues with your return jets, follow these maintenance tips:

Regularly inspect the jets for cracks or blockages.
Clean the jets periodically to remove dirt and mineral buildup.
Adjust the water flow direction to ensure even circulation throughout the pool.
Replace worn-out jets as soon as you notice decreased performance.
Check water chemistry levels to prevent scale buildup inside the jet fittings.

Common Mistakes to Avoid

When replacing a pool return jet, be mindful of these common mistakes:

Overtightening the new jet, which can crack the fitting.
Forgetting to turn off the pump, leading to water spraying or system damage.
Using the wrong size jet, which can affect water flow and filtration.
Not sealing the threads properly, resulting in leaks.
Neglecting to adjust the jet nozzle, which can create dead spots in circulation.

By following the steps carefully and avoiding these mistakes, you can ensure a successful replacement.
