Abstract
YA flow proportioning control for proportioning flow from a water level sensing valve. A barrier is positioned downstream from the valve adjacent to a refill line. A restrictor ring is positioned on said barrier with a portion overlying the upper surface of the refill line. It is interchangeable so that by substituting rings of various sizes, various proportions of flow can be selected.
