Spa walls bulge unevenly or lean when filled

Safety first: Do not use the spa if it appears unstable or at risk of tipping.

• Check ground: Ensure the spa is placed on a flat, level, and firm surface. Relocate if necessary.
• Adjust air pressure: Slightly deflate the spa to the recommended firmness; overinflation can cause bulging.
• Monitor shape: After adjustment, refill and observe whether the walls remain stable.

If deformation persists or worsens, internal structure damage may have occurred and the liner should be replaced.
