In the U.S, at least, boats can have a y valve that discharges overboard in the Great Lakes, but the must be shut off and locked off either using a lock or zip tie. I know this because in Chicago we used to have to have annual inspections (which in our old 27MKIII showed we had no Y valve at all).Now I will say, that is unless something has changed in the last few years...Bruce 1994 C&C 37/40+"Astralis"Sent from Samsung tablet. -------- Original message --------From: Chuck Saur via CnC-List <cnc-list@cnc-list.com> Date: 2/14/20 9:38 PM (GMT-05:00) To: cnc-list@cnc-list.com Cc: Chuck Saur <cssau...@gmail.com> Subject: Stus-List C&C 37+ -- Head Vented Loop? Edd...I had to disconnect and take the Y-valve out. As I understand it, you cannot have overboard discharge in the great lakes. Perhaps the PO of my boat did some earlier surgery...Chuck Saur517 490-5926 Cell
