Pool Cover Maintenance - The WAYNE 1/4 HP Reinforced Thermoplastic Pool Cover Pump is a great addition to your pool maintenance. WAYNE model WAPC250 has iSwitch technology, which activates the pump once the water level is at, or above 2 1/8”. Auto Off deactivates the pump when water is at or below 3/4" Automatic Pumping - Water level must be at least 2-1/8” for the pump to turn on, prime, and operate. Water levels less than 2-1/8” won’t activate the iSwitch to start the pump, so manual activation will be needed Efficient Design - Energy efficient, high flow, oil-free pump. Easy on/off allows you to plug in and leave the pump unattended for worry-free water removal all winter long. Automatic freeze protection within the iSwitch technology helps prevent pump damage Additional Features - The strainer base filters out debris to minimize clogging and keeps the pump from tipping over. 25-foot power cord and 25-foot "pull-to-shore" rope included to help position the pump on the pool cover. Includes a 3/4" garden hose adapter and check valve to reduce repetitive cycling Quality You Deserve - Proudly assembled in the USA for quality you can trust. Warrantied for 3 years for dependable, efficient, performance. This Auto Off pump will NOT run dry
