<b>Water Pressure, the Venturi Effect and Vacuum.</b><br><br> These three simple principles are what make Pump Marvel work.<br><br> 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 (Pump Marvel recently 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 and taking the water off of winter pool covers.<br><br> Pump Marvel will drain a hot tub down to 1/8″ in less than 20 minutes.<br><br> Includes a 12′ expandable 1 1/4″ (sump pump) discharge hose that is much easier to store than traditional hoses. Pump Marvel will also accept a 1 1/2″ pool hose.<br><br> A 1″ PVC pipe up to 4′ long can fit into the bottom of Pump Marvel which will allow it to suck water out of confined spaces, such as sump holes, washing machines and aquariums.<br><br> On the top of Pump Marvel there is a slot that will accept a standard pool pole handle, allowing Pump Marvel to be maneuvered and positioned with a pool pole.<br><br> Are you in the pool or spa service business? Pump Marvel is great for getting the last few inches of water out of an above ground pool when you are installing a new liner. And if you arrive at a service call to find that there is no electricity available to run your pump and the homeowner is not at home, use Pump Marvel to complete the job so that you don’t have to reschedule.<br><br> In many applications, such as removing water from a pool cover or draining a spa, Pump Marvel is safer than an electric pump because you are not mixing electricity with water.
