Thank you for contacting Biobidet Support.
I am sorry to hear your Flow Faucet Black control box is leaking!
Normally when the dial on the black box is turned too far down to the "lip" of the dial this would result in water leakage yes, the dial cannot be turned too far down over the lip.
If you are experiencing leaking of water from the box with the dial not fully turned past this point please submit your request to firstname.lastname@example.org and please provide a copy of your Proof of Purchase to activate your warranty so we can send out a replacement black box to resolve this problem.
