Abstract
A method for establishing a flow gradient along the gutter of a swimming pool of the type that includes a recirculating system for the pool water with said gutter comprising a portion of such system. The method comprises providing a plurality of gutter flow controllers at spaced locations around the perimeter of the pool. Each of such controllers includes an adjustable hydrastatic gate, the operation of which is responsive to the bias of an adjustable spring means. The gutter flow controllers are selectively adjusted to establish the desired flow gradient along the gutter.
