ABSTRACT:
A water flow control device, flow control system and method of using available swimming pool water for a source of water, adapted to be connected to conventional swimming pool hose apparatus for rapidly serving swimming pools for winter and spring cleanup. The flow control device can be used to rapidly fill water tubes, consisting of large vinyl bags which are used to anchor the four sides of conventional swimming pool cover used to cover swimming pools when not in use. The flow control device includes dual check valves, the first check valve controlling the flow and the second preventing reverse flow, a nozzle, a hose section, a valve housing, a flow control handle, a flow chamber, and check valve seats. The swimming pool flow control system incorporates a source of water and an improved flow control device, of 11/2" id., conventional vacuum hose and a plurality of water tubes, a submersible pump connected to pump water at high volume, low pressure, adapted to receive standard pool vacuum hose, for anchoring a generally rectangle cover for covering a swimming pool, typically partially filled with water when not used during periods of non use, generally in the winter months and cold climates. An alternate embodiment flow control system incorporates a nozzle control device having a unitary check valve for flow control connected to an in-line disconnect device and a union check valve having an internal check valve for preventing reverse flow.
