What this video covers

The crew of the C&C 39 Epiphany installs a macerator pump and Y-valve system to enable overboard discharge of the 35-gallon blackwater tank.2:44 Because the vessel was originally built for Great Lakes no-discharge zones, it lacked an independent pump-out system.1:38 The installation requires drilling a new through-hull fitting below the waterline, which reveals the boat's cored hull construction.1:05 The crew seals the through-hull with 3M 5200 sealant and mounts a custom 1x12 wooden platform to the hull to support the macerator pump and Y-valve.1:33 The plumbing configuration allows the tank to be emptied either via a deck-mounted pump-out fitting or through the new macerator and through-hull valve.6:38 To comply with U.S. Coast Guard regulations while in inland waters, the crew secures the Y-valve in the deck-pump-out position with a zip tie.8:27 The system is tested with saltwater to confirm the macerator functions correctly before future offshore use.7:30 Proper mounting and sealing of through-hull fittings are essential for preventing leaks and maintaining structural integrity in cored hulls.
