Possible Causes

Small puncture above waterline only visible when occupied, Evaporation due to high temperature and no cover, Leaking drain valve cap, Wicking through ground if base is absorbent

How to Fix / Troubleshooting

Safety first: Keep electrical components away from any pooling water.

  • 1. Use cover: Always keep the lid and cover on when not in use to reduce evaporation.
  • 2. Check drain valve: Inspect the drain valve and cap for drips. Tighten or replace the cap seal if needed.
  • 3. Inspect above waterline: Fill the spa and carefully inspect the upper walls for damp spots or weeping when the spa is occupied.
  • 4. Soap test for leaks: Use soapy water on suspect areas and look for bubbles.
  • If you cannot locate the leak: Consider draining, flipping the liner (if possible), and performing a more thorough inspection, or consult Lay‑Z‑Spa support.
