I was asked the question: Will the Ram Pump work underwater? Find out in this adventure.

The pump does work underwater but the hydrostatic pressure negates the added head pressure.

I take the 1-1/4" drive pipe ram pump and place it above the water to see what output it has with 2.5 feet of head. Next I take the pump and submerge it two feet in the water. This adds two feet of head so the pump is able to pump higher. But I feel the pump is somewhat less efficient because the valve is having to move water out of the way to operate. One added benefit of having the pump underwater is that the clicking noise it much reduced.
