The heads in the boat were installed in the late 90’s. They are all identical (thank goodness), full size, fresh water units. Before we left Virginia I had 2 of the 4 operating marginally. The plan was to overhaul the units once we got to warm weather. And here we are….I had found the Raritan Engineering warehouse on one of my outings in Fort Lauderdale and pick-up 3 service kits for the heads…all I have to do is take the heads apart one at a time, check the pieces and parts, replace worn items and put it back together.
I didn’t mention how discusting taking these things apart is….they stink and your touching things that have been covered in other people’s waste. Glove time.
One related issue was a y-valve that was frozen in place. The waste plumbing at each head will drain directly into the holding tank or overboard. In the islands there are no pump out facilities. It is requested that you use your holding tank when anchored in the harbors. Outside of the harbors, you pump your waste overboard.
I removed the valve, lubricated the ball and shaft and used a hair dryer to heat the valve. After an hour or so the valve became workable and it was reinstalled.
