I agree with you totally with the cold water kit on the Odin. I've had it 6 mounts and have had to patch the rubber boot twice. This is why I like the conshelf so much. You can't accidentally damage the cold water kit. About half of the tech divers here using Odins don't even use the cold water kit. I kind of figured that if the odin would freeflow it would hit hard but I thought the only reg that would shut down was a dacor. Randy Sullivan Sault Ste.
