I didn't use the faucet adapter with mine. I am using the garden hose adapter and have it set up in my basement next to my clothes washer. I got a $5 Y connector for the water hookup and have one side going to my washer and the other to the RO unit. I just drain the waste water right into my washing machine. Works out great. I can get about 10 gallons of RO water then I have to run the spin cycle to drain all the waste from the washing machine.
