An 8-foot standard black water tube designed to secure winter or protective pool covers on in-ground swimming pools. Made from heavy-duty vinyl with a leak-proof valve, this water tube helps prevent pool covers from sagging into the water due to wind, debris, or ice load during cold-weather storage.

This single-chamber water tube is easy to fill with a garden hose and can be positioned around the pool perimeter to provide reliable support beneath the cover. Its durable construction and tight-seal valve make it a dependable accessory for maintaining pool cover integrity throughout the off-season.
