DescriptionThe Waterra SS-13 Foot Valve (Stainless Steel) is part of 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 groundwater 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 1/2” (13 mm). This narrow diameter means that they will often fit into piezometers that can not be accessed by the Standard Flow System.The Waterra SS-13 Foot Valve is recommended for narrow diameter wells where chemical compatibility may be an issue.
