Q: Will this clean the faucet in addition to the beer line? Or does the faucet need to be removed and cleaned separately?
A: This will rinse the lines and the faucet (the faucet is where the cleanser exits during the cleaning process)

BL Cleaning Kit
I have to agree with a previous review. I really had to crank down on the bottle fitting to get it to seal. Would recommend soapy water for testing rather than submersion. Also, the 14" tube was cut at 24" and could not be effectively inserted into the bottle! Once these problems were fixed, it worked great with water. Have to empty a keg before trying BLC.
Great for ball lock kegerators
Just plug this into your beer ball lock in your kegerator, fill and pump to flush the lines. Very easy once you figure out how to assemble the pump.
Leaking problem fixed
I used three Ford expansion valve O-rings to seal it. It works perfect now. They are very thin and fit perfect. Something Williams should include in the kit !!!
Easy
Plugs into beer line, no pulling faucet from tower. Just mix solution connect beer line open tap and pump. Repeat with a rinse and your done.
Works but..
I found that you really have to crank down on the fittings in order to stop any air leaks. It won't pump fluid if there are leaks. It seems to be right at the edge of overtightening or striping the threads so I'm not sure how long this thing will last.
