Leaky Black Tank

[steveirving]

Hi,

The black tank on my .59 Tradewind is has a drip coming from where the metal threaded flange connect onto the black tank. I suspect the seal between this vintage metal connector and the plastic/fiberglass black tank has weakened over the decades.

I know pulling the toilet and tank is unavoidable. Any recommendations on cleaning up and getting a tight seal between the metal collar and the black tank? Epoxy? Fiber glass repair kit?

Hi,

Thought I would add some pics to try to get some advise on repairing out black tank.

I took pics of the dump valve area, the black tank and vent pipe, and the toilet area which has the black tank under it.

The black tank seems to be leaking from the top of the 3" metal fitting that the dump valve screws into. I assume the 3" metal fitting is attached to the black tank by screws and some gasket material.

What is the best way to got about getting access to this area of the tank and repairing this connection point?

I would Try to unscrew the V valve and the coupler that is connecting to the metal fitting. Form there you might be able to see if the metal fitting is part of the tank, or is screwed into the tank. It might be as simple as unscrewing it. Adding new gasket/ sealer and then putting everything back together. If that does not work, then the section of the belly pan in that area appears to be screwed on with flat head screws? Once that plate is pulled down you should have a good view. It looks like your holding tank is above the floor, so there must be some kind of pipe running from the tank, through the floor, and through/ out the belly pan. Oh yea clean the tank out real good before getting to work!!

Great blog, and a fine job getting the new composting toilet installed. It looks great. Please let us know how it works out.

How do you get the composted waste out? Is the a tray you carry out and dump?
