Spa liner loses air and becomes soft over several hours or days.

Safety first: Do not overinflate the spa to compensate for leaks; this can damage seams.

• Locate leak:
  • Inflate the spa to normal pressure.
  • Spray soapy water on seams, walls, and around the inflation valve; look for bubbles.
• Repair punctures:
  • Mark leak locations and dry the area.
  • Use an Avenli vinyl repair patch kit according to instructions.
• Check inflation valve:
  • Tighten the valve insert with the supplied tool.
  • If leaking around the valve body, replace the inflation valve assembly.
• Re-test: Reinflate and monitor pressure over 24 hours.
