QCA Spas Hidden Plumbing Leak in Foam

Spa cabinet or base shows signs of water damage or constant dampness with no obvious equipment leak.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Cracked plumbing line in foam insulation, Leaking jet body behind shell, Freeze damage to manifolds, Loose hose clamp

Safety: Turn off power and avoid using the spa until the leak is located and repaired.

Locate wet area: Remove side panels of your QCA Spas cabinet and inspect the foam for wet or discolored areas.
Excavate foam: Carefully remove wet foam around the suspected leak path to expose plumbing.
Repair plumbing: Replace cracked PVC fittings or manifolds with new parts and PVC cement. Tighten or replace hose clamps on barbed fittings.
Re-insulate: After repair, refill the cavity with spray foam or insulation to restore energy efficiency.
