How to Fix / Troubleshooting

Safety first: Turn off power and lower water level below the damaged area before repair.

  • Assess severity: Hairline surface cracks without leaks may be cosmetic. Cracks that weep water require repair.
  • Dry area: Thoroughly dry and clean the damaged area with a non-abrasive cleaner.
  • Use repair kit: Apply an acrylic spa repair kit matched to your Aquavia shell color, following the kit instructions (filling, sanding, and polishing).
  • Monitor: Refill above the repair and check for leaks. Extensive structural damage may require professional shell repair or shell replacement.
