PRO TIP
Never use petroleum-based jelly (like Vaseline) on the O-ring; it will cause the rubber to swell and degrade. Always use a pool-grade silicone lubricant to maintain a watertight seal and extend the life of the lid.
Always follow label directions and safety guidance. Keep pool chemicals and accessories stored safely and out of reach of children.
