This system consists of a low flow valve, either the acetal plastic D-13 foot valve or the stainless steel SS-13 foot valve and HDPE, LLDPE or FEP (Teflon) tubing.
The Low Flow System is probably most frequently operated by hand, although the Waterra Hydrolift II can also be used to operate this system.
The Low Flow System is also useful for sampling in damaged or obstructed monitoring wells.
