There were no responses to my question so I decided to reconfigure the pool plumbing so that I could direct return water to the nozzle in the pool through a Jandy 3 way valve in one postion. When I switch the Jandy valve 90 degrees to the second position it stops the flow of water to the nozzle and connects the nozzle in the pool to the an overflow stand pipe.. The system works perfectly. Water is now retruned to the pool through a 1/2" nozzle and when we are away, I can use the nozzle as an overflow by turning the Jandy valve 90 degrees. Bill
