Is this a necessary part? I dropped my r/o system and the waste water hose broke off at this end. It connects to the white block which is supposed to be the auto shut off. Where can I get another one if I need it. Also, where do you keep your r/o systems at? I keep mine outside on the porch so that the waste water can be used on the lawn. I am getting algae inside the first chamber which is the carbon.
