V32 Waste Tank Update
I spent a good bit of the weekend installing a new waste tank and hoses behind the head at the foot of the aft berth. The tank is a Ronco B191 (30 gallon) and fit the hull shape fairly well. My original plan was to support the tank first on a platform, shim between the tank and hull, then pinch the tank in place with a bulkhead panel. This method probably would have been easier than what I actually did. I thought it would be best to mount the tank to the bulkhead, then fix the bulkhead in place. Because there isn't a lot of room to work in that area, I wrestled with it and eventually had to cut about 18" of the length of the bulkhead panel to get it into place.
I used the 1-1/2" Trident 102 hose, and boy is that stuff hard to bend. It's outside diameter is larger than the hose I removed, so I had a difficult time getting everything to fit in the area of the pumpout fitting, vent thru-hull, and vent loop. Since I connected the vent loop and hoses outside the head, this assembly had to go in first and just barely fit. Then the pumpout hose went up BEHIND the vent loop, meaning that the vent loop can't be screwed against the wall. Finally, I replaced the vent thru-hull with a straight 3/4" thru-hull and 3/4" hose.
Unless someone speaks up, my plan for the old tank is to let it dry out for a week, then close the three holes with resin and glass fiber. I don't think the tank had developed a leak yet. If I still have odor after everything is complete, I'll bore a 4" hole in the side, glass the inside of the tank, then close it up with a cover.
