Part Number: 1144
Description
This inflatable air pillow is designed to be placed under your pool cover to absorb ice-expansion pressure and help prevent water and debris accumulation in the center of the pool during winterizing.
Compatibility & Fitment
- Size: 4 feet by 4 feet – suitable for many above-ground and in-ground pool covers.
- Designed for use during winter pool closing with a solid cover.
- Use when the pool is covered for the off-season and you want to reduce stress on pool walls and cover fabric.
Features & Specifications
- Inflatable vinyl cushion approx. 4′ × 4′ in size.
- Helps relieve pressure from freezing water expansion and prevents water/sludge from pooling in the center of the cover.
- Durable vinyl construction designed for seasonal use under pool covers.
Installation Notes
With pool drained per cover instructions, inflate the pillow about half-full and place it in the center of the pool before installing the winter cover. Make sure it sits flat and let the cover secure around it. After winter, deflate, clean and store the pillow for reuse.
Maintenance Tip
Before reuse each season inspect the pillow for punctures or seam leaks. Patch minor leaks with vinyl repair kit or replace if damaged. Inflate moderately to prolong life and avoid over-inflation that can stress seams.
