DescriptionHere’s How a Waterra Pump WorksThe Waterra Pump Nano Flow System is a simple, inexpensive way to sample a monitoring well. This is how it works.A Waterra Foot Valve is attached the bottom end of a length of Waterra Tubing.The Foot Valve – Tubing combo is inserted into the well, Foot Valve first, until the valve is submerged beneath the water table to the desired pumping depth.The tubing is then oscillated (pulled up and then pushed down) over a short vertical range of motion either by hand or with a Waterra Tubing Actuator.Water builds up in the oscillating tubing until it discharges at surface.
