Important Instructions for the Countertop Reverse osmosis system.
Here are the ways the countertop systems are installed with the diverters.
The diverters attach to the thread on the end of the spout or tap where the aerator usually is, to the below left is a photo of the aerator removed from the tap so you can see what they look like, this one has male threads but there are also female
The right picture of the male - male adapter that is included with the system to adapt female threaded taps to accept the diverter.
The image on the below is with the filter system off and the water goes into the sink as normal, when the handle is turned the water is sent through the reverse osmosis system and the good water comes out the white tube, the rejected water (waste) comes out the black tube.
