You take off the end of the sink filter & screw it on like you do a hose in the garden but the threads on on the outside & it screws up into the sink.
Might be better to get a attachement that attaches to a hose outside as a big problem with hooking it up to the sink is no matter how tight I make it or adjust the couple end water squirts out the side by the attachment & sprays all over the place...
Maybe I need a different attachement end or washer or something
but that's as it came & its a hard to use because of it
