performed one of the least desirable chores for a boat owner this weekend and replaced my Jabsco mascerator pump for my waste holding tank. Not only are you dealing with toilet contents but to access my holding tank I had to take off a big access plate on my pod where the tank is stored. Hadn't had that open in my year or so of ownership so that was good to see nonetheless. The pump was mounted on top of the holding tank to I swapped it out, heat shrank the connections, and reattached the hoses so that I could once again pump **** out. great times. Had to re-seal my access hatch with some sikaflex marine sealant which is great stuff but it's still all over my hands. Stupid me didn't have nitrile gloves for the job. Won't make that mistake next time.
