Spa is leaking water inside the cabinet or around the base.

Safety first: Turn off power at the GFCI breaker. Avoid standing water around electrical components.

• 1. Locate the leak: Remove side panels and inspect around the pump, heater, and plumbing while the spa is filled. Use a flashlight to trace drips back to their source.
• 2. Tighten unions: Hand-tighten pump and heater unions. Do not overtighten with tools, as this can crack fittings.
• 3. Check drain valve: Inspect the Coleman drain assembly at the base. Ensure it is fully closed and the cap is tight. Replace the drain valve if it is cracked or seeping.
• 4. Jet body leaks: If water is seen around specific jets, the jet body gasket may be failing. The spa may need to be partially drained and the jet body resealed or replaced from the backside.
• 5. Structural plumbing leaks: Cracked PVC lines or manifolds often require cutting and replacing sections of pipe with new fittings and PVC cement. This is typically a job for an experienced spa technician.
