Winterizing device for inground swimming pools |
摘要 |
A device for use in winterizing inground swimming pools avoids the necessity of draining the pool in order to drain underground water-filled conduits before freeze-up. The device is an elongated cofferdam open at top and rear with a groove for receiving a sealant extending along the rear edge of side and bottom walls. The sealant, such as a denture adhesive, will hold the device against the pool side wall surrounding a water inlet, and so that the device opens above the water surface. Water within the device and the conduit leading to the inlet is pumped therefrom and then a plug is inserted in the inlet to prevent pool water from entering the inlet after the device is removed from the pool side wall.
