I am installing a new bilge blower because mine is so loud I can't tell if my motor is running without looking at the tach. I am going with one of the newer inline style blowers. While I am at it I would like to redo the tubing leading to the bilge. I was wondering if there is any reason one couldn't use rigid 3" PVC pipe? It would make for a much cleaner look and would last darn near forever. I just hate the look of the "dryer vent hose." I would use a rubber flex coupler from the tubing to the blower. Has anyone ever done this before? Pros/cons???
