Maintenance Tips
- Inspect tubes at the start of the season for pinholes, seam wear, and valve damage before placing them on the cover.
- Keep tubes away from sharp deck edges and rough concrete that can cause abrasion over time.
- At spring opening, drain, rinse, and store loosely folded in a cool, shaded location to help extend vinyl life.
- If a tube repeatedly leaks at the valve, replace the tube rather than overtightening or forcing the fitting.
