I have an R O water filter system. The water kept leaking out the air hole in the faucet. I got a new faucet and the same problem occurred in it. So I went to the web, and your sight solved my problem. My drain hose was blocked. I cleaned it out with a wire and left it unconnected to drain pipe because I am amazed at how much water comes out of that drain hose (the hose that some are calling the black hose). I seem to be waisting a gallon of water every 1/2 hour. My question now is: Is it normal to waist that much water? I also just changed all the filters in the system. Maybe that is why I am temporarily waisting so much water?

Thank you, M Lewis
