SPA392 Series – Leaking Jets : How to fix
Using the 3-Prong Jet Tightening Key to tighten the Jet (video below)
Step 1. Position the Tool
Hold the 3-prong tightening key so the three raised posts line up with the three matching holes on the front face of the shower jet.
Step 2. Insert and Engage
Press the tool gently against the jet face until all three prongs sit securely in the holes.
Step 3. Tighten or Loosen
- To tighten the jet: turn the tool clockwise until snug.
- To loosen or remove the jet: turn the tool counterclockwise.
Step 4. Check Alignment
After tightening, make sure the jet face is even with the panel surface and oriented correctly.
Step 5. Test for Leaks
Turn the water back on and check. If water seeps around the edge, re-tighten slightly with the tool.
