DescriptionThe Waterra SS-6 Foot Valve (316 Stainless Steel) is part of the Nano Flow System is designed to be used in drive points (usually 0.5 inch (12.5 mm) ID). It can provide flow rates of up to 1/4 gallon per minute (1 lpm) and can lift groundwater up to 50 feet (15 m).The Waterra SS-6 Foot Valve has a thread so it threads into the 0.17 in x 1/4 inch OD tubing. The system with an SS-6 therefore has a maximum outside diameter of 1/4” (6 mm). This narrow diameter means that they will fit into narrow or obstructed piezometers.The Nano Flow system is usually operated by hand and requires Waterra Nano Flow HDPE or LDPE Tubing.There is not an acetal thermoplastic (Delrin) equivalent foot valve.
