Fixing a leak between the TurboSpa and the shower arm
A leak at this connection almost always comes down to the internal washer — either it has shifted out of place during installation, or it isn't sitting flat enough to create a proper seal. This is a straightforward fix that takes just a few minutes.
Step 1 — Check and reseat the washer
Remove the TurboSpa from the shower arm by turning it counter-clockwise. Look inside the connection nut and check the rubber washer. It should be sitting STRAIGHT and FLAT against the inside of the connection. If it has shifted or curled at the edges, use a screwdriver or pen to gently press the edges back down until it sits flush. Reattach the shower head and test.
Step 2 — Flip the washer
If the leak continues after reseating, the washer surface may be slightly worn on one side. Use a screwdriver to remove it from the connection nut, flip it over so the other face is forward, and reseat it flat. Reattach and test again.
Step 3 — Apply plumber's tape
For a persistent small leak, wrap plumber's tape around the shower arm threads — 3 to 4 layers, applied in the direction of the thread. The tape fills microscopic gaps in the thread and creates an additional seal. Reattach the TurboSpa hand-tight and test. This usually resolves any remaining drip.
