My seacock to that lovely sink is 1/2 inch as well as the thru hull. I have bought a new thru hull which is a match to what I have, it's marelon. The seacock I found is 1/2 inch to fit it. It screws down to the inside of the hull with out a backing plywood is this because it is so small? I need to get an adapter Male 1/2 inch Female 1 inch. Anybody come accross this problem. The drain in the sink does anybody know what the original measurement was and where do you get the parts. West does not have the male to female adapter and I am not sure on the drain the pipe was 1 inch. Definitely not original. The first pipe was 1-1/2 according to the manual.
