Low Flow Foot Valves
The Low Flow System is designed to be used in small diameter piezometers (usually 1.5" ID to 0.75" ID). It can provide flow rates of up to 1/2 gallon per minute and can lift water from up to 100 feet.
The Low Flow System D-13 and SS-13 valves have a male thread which allows them to have a maximum outside diameter of 5/8” (13 mm). This narrow diameter means that they will often fit into piezometers that cannot be accessed by the Standard Flow System.
In some deep well situations it may be necessary to secure the Low Flow foot valve to the tubing with a small screw. In deeper wells the hydraulic pressure applied against the tubing where the valve can be substantial. This pressure pushes against the walls of the tubing and against the valve and may ultimately pop the valve out of the end of the tubing.
The use of HDPE tubing is preferred in these situations because it is stiffer than the LDPE tubing and will expand less under high pressure. Additionally, the valve can also be securely fastened to the tubing by driving a small sharp stainless steel screw through the tubing wall, penetrating the threaded portion of the foot valve. The stainless steel SS-13 valve has a small hole in the threaded portion of the valve which will accept screws used for this purpose.
Recommended Devices
The Low Flow System is probably most frequently operated by hand, although the Hydrolift-2 and a Lever Pump can also be used to operate this system.
Damaged Wells
The Low Flow System is also useful for sampling in damaged or obstructed monitoring wells as well as in small diameter monitoring wells with low head levels or poor recharge.
The smaller diameter tubing used in the Low Flow System and lower flow rate produced by this system means that the pump itself contains a smaller volume of water when full, leaving more water in the piezometer available for pumping and ultimately sampling.
A pump with a larger storage volume or higher flow rate could potentially purge the well dry or displace the all of the standing water in the well into the pumps tubing and still not have delivered any all of the way to the surface.
Performance Chart
The Performance Chart shown displays the performance capabilities of the Low Flow System. This chart is intended to assist you with the selection of the most suitable system for your specific site.
Please note that the ratings have been calculated by actual field testing in a variety of well conditions and therefore may seem somewhat conservative in value.
