Multiple Uses : • Draining spas and hot tubs – drain your hot tub in less than 20 minutes. Safely removing all the water from pool covers. Preventing flooded basements during a power outage. Removing unwanted water from construction sites, flat roofs, patios, lawns, washing machines, dishwashers. Effortlessly bail boats. Emptying blow-up pools, kiddie pools, fountains and koi ponds • Pump Marvel Outperforms Traditional Submersible Pumps : It drains water down to 1/8in so you don’t have to worry about manually removing the other 2 – 3in that a submersible pump leaves behind. No more getting into your hot tub to bail out the last few inches of water left behind after draining. If there is debris in the water that is being drained, i.e. leaves in the water on the top of a pool cover, the debris will not block the intake as long as Pump Marvel is positioned flat on the bottom, a feat that can easily be managed by one person by using a standard pool pole that attaches to the top of Pump Marvel. Traditional submersible pumps have an intake screen that can rapidly become clogged with small debris, causing the pump to quit working and even burn out. • Pump Marvel is great in situations where there is shallow water to move. For example, if you had a leak in a basement, Pump Marvel can keep water at bay leaving as little as 1/8? behind. Without Pump Marvel you would need to use a shop vac and continually be vacuuming water up until the source of the leak was stopped. The benefit of Pump Marvel is that you can turn it on and leave it alone, freeing you up to do other things (like find the source of the leak). Comes with an expandable/retractable • Water Pressure, the Venturi Effect and Vacuum.These three simple principles are what make Pump Marvel work. • Pump Marvel is a pump that uses pressure from a garden hose, rather than electricity, to pump water. While not intended to outperform the speed of electric submersible pumps, Pump Marvel is great in situations where you can’t use electricity. 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 and taking the water off of winter pool covers. • Product Dimensions 12.5 x 3.75 x 8.1 inches • Item Weight 1.28 pounds
