Abstract
Foaming and lateral water leakage during the filling of a container with a foam-prone water/chemical mixture is minimized by using, at the inlet of the venturi nozzle which draws the chemical into the water, a water authority-approved resilient-sleeve air gap which furnishes air-free water to the venturi while providing a siphon-breaking air gap if water is not flowing into the venturi.
