ikinne1, you mentioned a garden hose adapter. This is the solution i am looking for. How would I do that? I just got my RO/DI unit, and the directions suck, along with the fact I cannot pierce the pipes cuz its a rental place. Can i just attatch a piece of pipe to my garden hose, pierce that, and let the waste water drain outside? Is it that simple, or am i missing something? Thanks.
