The GreyLink transfer station is an optional component which is utilized when the building's greywater stub-out is lower than the intake port on the GreyLink Greywater Processor. Greywater is immediately pumped out of the transfer station upon entrance. A sump pump and float switch are included to automate the process. When greywater flows into the transfer station, it is immediately pumped into the GreyLink Greywater Processor.
