Possible Causes
Leaking pump union O-rings, Cracked heater manifold, Loose drain fitting, Split PVC plumbing near control pack
How to Fix / Troubleshooting
Safety: Turn off power at the breaker before working near water and electrical components.
- Step 1 – Remove access panel: Open the equipment compartment and use a flashlight to locate the source of the leak while the spa is filled.
- Step 2 – Check unions: Inspect pump and heater unions for drips. Gently tighten by hand; if still leaking, replace the union O-ring.
- Step 3 – Inspect heater manifold: Look for cracks or leaks around the heater tube and sensor ports.
- Step 4 – Examine drain assembly: Verify the drain cap and hose are fully closed and not cracked.
Cracked PVC or heater manifolds usually require cutting and replumbing; this is best handled by a spa technician.
