Water level in spa drops noticeably over a day or two with no visible equipment bay leak.

Safety first: Turn off power at the GFCI breaker if water level drops below suction fittings to prevent pump damage.

• 1. Inspect shell and fittings: Look around all jets, suctions, and lights inside the spa for signs of water seepage or discoloration.
• 2. Dye test: With pumps off, use a small amount of food coloring near suspect fittings to see if it is drawn into a crack or gap.
• 3. Check around base: Walk around the spa and feel for soft or wet spots in the ground or deck that may indicate a leak location.

Because accessing plumbing behind the shell often requires cutting foam and specialized repair techniques, hidden leaks are best handled by an experienced spa leak specialist.
