Water Pump; Pumps Water Out!
Water Pressure, the Venturi Effect and Vacuum. Three simple principles make Pump Marvel work. Pump Marvel is a hot tub drain pump that uses pressure from a garden hose, rather than electricity, to pump water. While not intended to outperform the speed of electric submersible hot tub drain pumps, Pump Marvel is great in situations where you can’t use electricity (Pump Marvel saved one person’s basement from flooding when the power was out and the sump pump wasn’t running). It also works great in areas where, for safety reasons, it may be preferred not to mix water and electricity, such as draining hot tubs or taking the water off of winter pool covers. Pump Marvel will drain a hot tub down to 1/8″ in less than 20 minutes; 13 times faster than siphoning or draining with a garden hose. It does not lose its prime. It can lift discharge water up to 20′ high. Pump. Marvel. Enjoy!
