ABSTRACT:
A perimeter skimming gutter for swimming pools is provided including a gutter conduit for disposition about the perimeter of a swimming pool and adapted to carry water at a level below a predetermined level of water in the swimming pool; a retaining wall on the pool side of the conduit over the top of which wall water may flow from the pool into the gutter conduit; a weir flow passage providing a fluid flow connection between the pool and at least one gutter conduit, entering the pool through the retaining wall at a level below the top thereof; and a fluid level responsive buoyant weir closure in the weir flow passage; a flow restriction in the weir flow passage confining normal weir flow through the weir flow passage to the gutter conduit to a predetermined maximum, the flow restriction blocking flow in excess of the predetermined maximum and thereby increasing fluid level in the weir flow passage between the weir closure and the pool; the weir closure responding to increasing weir flow passage fluid level to close off the weir flow passage at a predetermined level above the normal weir flow level.
