Hot Spring Hidden Plumbing Leak in Foam Insulation

Water level drops slowly over days with no obvious external 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 manifold inside foam, Leaking jet body behind shell, Small split in flex hose, Freeze damage to plumbing

Safety first: Turn off power if water level drops near suctions or equipment.

Mark water level: Use tape to mark the water line and monitor drop over 24–48 hours.
Inspect accessible areas: Remove side panels and look for damp foam or water trails.
Isolate height of leak: Allow water to drop until it stabilizes; the leak is often at or just above that level (e.g., a specific jet line).

Locating and repairing leaks inside foam typically requires specialized tools and is best done by a Hot Spring service technician.
