i need some ro unit advice ,so my ro unit sits under the sink, its got a 3.5gallon vac tank and elecky pump with a drinking water tap on the sink,
is there a gizmo that turns it all on and off on demand? im fed up of having to turn it all on and then back off to stop wasting water because when its full it keep on pouring water down the drain
ive found this but that wont turn the pump off
any ideas ?
