NetSpa inflatable walls feel soft or sagging even after inflation; spa loses air over time.

Safety first: Keep electrical components away from wet areas while inspecting the spa body.

• Check valve: Ensure the inflation valve is fully closed and the cap is tight. Apply soapy water around the valve to check for bubbles.
• Inspect for leaks: Spray soapy water on seams and suspect areas; look for bubbles indicating air leaks.
• Patch leaks: Use a NetSpa-compatible PVC repair kit to patch any identified holes or seam issues.
• Account for temperature: Cooler temperatures reduce air pressure; top up air when water or ambient temperature drops significantly.

Extensive seam leaks may not be reliably repairable and can require replacement of the spa body.
