Would like to plumb another water supply to one of these for RO reject water. Would anyone out there know precisely how to do this? The pumping unit is in a small almost closet and is a jumble of hoses. Thanks.
Gravity feed it if you can, too risky having a pump feed the source water. My RO reject sits above my 360’s and I feed the pump (Not the solution pump, it gets a hot water feed) and I have a 2” hose feeding the Cat pump.
