Applications & Fitment

This tool is ideally suited for spa or gunite pool jets built with Waterway’s poly jet housing systems. It is particularly useful when servicing screw-in jets where the housing or internal insert needs replacement, or when testing plumbing runs by temporarily capping a jet port. Confirm your jet body model prior to use to ensure compatibility.

Usage Instructions

• Turn off all circulation and relieve water pressure in the spa/pool before servicing.
• Use the wrench end to engage the flats of the poly jet faceplate and apply leverage to install or remove the jet housing.
• For leak or flow testing, reverse the tool and insert the plug end into the jet port, seating it securely to allow testing of the plumbing run.
• After servicing or testing, remove the tool, reinstall proper jet insert or housing, restore circulation, and inspect for correct operation and sealing.

Troubleshooting

• Wrench won’t engage jet faceplate: Check that the jet faceplate is the Waterway poly screw-in style and that the tool’s flats match; some deluxe or alternate jet models may use different dimensions.
• Test plug leaks or doesn’t seat: Confirm the port is clean, the seat surface is flat and free of debris; ensure proper orientation of the plug end and re-test.
• Tool cracked or deformed: Discontinue use and replace—damage can compromise service safety and lead to jet/housing damage or injury.

Maintenance Tip

After each service use, rinse the tool to remove chemical residue, inspect for any wear or cracking, and store in a dry, shaded location to prolong life. Keeping this service tool in good condition ensures smooth jet servicing and helps reduce downtime on spa or gunite pool maintenance jobs.
