Solinst Waterra Pump 404
The Waterra Pump is a simple, reliable inertial pump that provides a cost effective sampling option for groundwater monitoring.
The Pump consists of a riser tube fitted with a one-way footvalve. It can be easily operated manually at shallow depths, or by using a surface pumping mechanism. The tubing and footvalves come in a range of sizes suitable for most well diameters and sampling applications. A 1/4" (6 mm) Mini Inertial Pump is available for sampling inside CMT Multilevel Systems.
The Waterra Pump is a simple alternative to using a bailer. Like a bailer, the key part is the check ball which is located in the foot of the pump. As such, the Waterra Pump is often referred to as a ‘footvalve’.
