The 591 Water Diverter Valve screws on end of faucet and provides an easy way of directing water to any wall mounted chemical dispenser. The 591 has a built in pressure bleeding device for compliance with ASSE 1055 when connecting to a faucet with a backflow preventer not rated for continuous pressure.
The 591 bleeds pressure from the faucet by discharging a narrow stream of water into the sink from the
device when the faucet is open. This relieves enough pressure to not damage the faucets backflow
preventer, provides a visual indication to turn the water off and eliminates hot cold cross connection
