Step 1: Power Off and Drain the Hot Tub
Although some users mentioned difficulty checking the jet because the tub was full of water, draining at least below jet level is necessary for safe replacement.
Step 2: Inspect the Jet from Inside the Tub
Shine a light through the opening:
If you see a hexagon, use the matching Allen key to loosen it.
If no hex shape is visible, leave it—forcing it may damage the housing.
Step 3: Loosen the Jet Face
Insert the Allen key and turn counter-clockwise.
Do not apply excessive torque.
If the jet seems "not going anywhere," it's probably bonded with silicone or overtightened at the factory.
Step 4: Access the Backside of the Jet Housing
From the equipment bay or exterior panel, locate the jet body.
Check whether it is:
1. threaded into the shell, or
2. Silicone-bonded
This distinction determines how the hot tub ozone jet replacement will proceed.
Step 5: Disconnect the Ozone Line
The ozone injector line is usually a small flexible tube connected to the jet body.
Gently detach it to avoid tearing.
Step 6: Remove the Jet Body
If threaded:
1. Remove using pliers or a jet wrench.
2. If silicone-bonded:
3. Cut through the silicone gently with a razor knife.
4. Peel away adhesive.
Step 7: Install the New Ozone Jet
Ensure:
1. Correct orientation
2. Proper alignment with shell
3. No gap around the seal
4. Ozone line fully seated
Step 8: Tighten the Jet and Test for Leaks
Refill the spa above the jet.
Check for dripping, seepage, or air bubbles on the exterior side.
