Possible Causes
Slow leak from jet body, Manifold, or plumbing joint buried in foam, Long-term seepage from pump or heater unions, Freeze-damaged plumbing
How to Fix / Troubleshooting
Safety first: Turn off power at the GFCI breaker if water is near electrical components.
- Confirm water loss: Mark water level and monitor over several days to quantify loss.
- Inspect accessible areas: Check equipment bay and visible plumbing for obvious leaks first.
- Foam excavation (advanced): Carefully remove cabinet panels and dig into foam insulation near the wet area to trace moisture back to the source. This is labor-intensive and often best done by a professional.
Once the leak source is found, repair or replace the affected fitting, manifold, or jet body, then re-insulate the area with spray foam.
