Water Pressure, The Venturi Effect And Vacuum Pump Marvel For Uses Pressure From A Garden Hose
Brand: The Spa Marvel Company

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 (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.
Pump Marvel will drain a hot tub down to 1/8″ in less than 20 minutes.
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.
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.
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.
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.
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.

Pump Marvel is Not a Siphon, it is a True Pump: It doesn’t lose its prime. It can lift discharge water up to 20′ high. Pump Marvel drains 13 times faster than siphoning or draining with a garden hose.
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 1/8″ so you don’t have to worry about manually removing the other 2 – 3″ 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/retractab
