Blue Wave 8-ft Double Water Tube for Winter Pool Cover - 5 Pack

Features

• Anchors In-Ground Pool Covers: These 8-ft double pool water bags anchor in-ground winter covers in place to resist wind lift and stop debris buildup; keeping the cover secure reduces the risk of slips and accidental falls, helping the pool area stay safer for families
• Heavy-Duty 18-Gauge Vinyl Construction: These water tubes are built from puncture-resistant vinyl with reinforced seams engineered to hold up through harsh winter conditions, withstanding -10F up to 180F without cracking or stiffening
• Prevents Cover Shifting and Wind Lift: Each water tube spreads even pressure along the pool edge to stop shifting and wind lift all season; fill each tube to three-quarters full to leave room for expansion as water freezes
• Dual-Chamber Design: Featuring two independent chambers, these pool cover weights distribute weight evenly; if one chamber is ever compromised, the second keeps the cover anchored
• Easy to Drain for Storage: When spring arrives, these water tubes for pool covers drain completely with no pump needed; simply open the valve, tip and store flat until next winter,
• Fills Fast with Any Garden Hose: These pool weight bags connect to any standard garden hose through an oversized, leak-resistant valve and a secure push-in plug cap that seals tight all winter
• Bends to Fit Any Pool Shape: The flexible design of the pool water weights allows it to curve around kidney-shaped, freeform or rectangular edges to fit solid, mesh or hybrid covers; also works to weigh down leaf nets and summer pool covers with ease
