Waterra Stainless-Steel Foot Valves are used with Waterra Tubing and (optionally) with a Tubing Actuator. Stainless-steel foot valves are recommended when there is concern about chemical inertness or a tight well inner diameter. They can also be decontaminated for re-use.

The Waterra SS-19 Foot Valve is made of 316 Stainless Steel and has a 3/4 inch (19 mm) OD. It threads onto Waterra Standard Flow Tubing (1/2″ x 5/8″).
