If you are considering a complete Standard Flow System perhaps this link will help you select the matching components.
A Waterra D-16 Foot Valve threads into Standard Flow Tubing for sampling narrow diameter piezometers.
The D-16 Foot Valve is best used for narrow diameter wells as the Outside Diameter of the Valve is 16 mm (5/8 inch). It would fit nicely in a 1 inch ID well for instance. A stainless steel alternative is the SS-16 Foot Valve which also threads into the ID of the tubing.
For 2 inch wells we would normally recommend a D-25 Foot Valve.
The Standard System with a D-16 Foot Valve can provide lifts of 150 feet(45 m). Flow rates can be as much as 1 gallon per minute (4.5 lpm).
