I cracked off black water tank connector to toilet!?

[Argosy72Clem]

So if you can imagine a very rusted toilet connection... it was nearly impossible to disconnect the connection from the bottom of the toilet so it ended up getting pryed off. Well, that ended up in cracking it off the black water tank. I got the connection off of the bottom of the toilet and just fit it back in the spot on top of the black tank. How should I proceed now??? The main goal was to plug it up and put my natures head on top of the platform.. saving the tank for a future used if they wished to use it... but I don't know!? Please help

A photo would help a lot. You might need a new tank, But your polyethylene tank flange might be able to be welded if you can get at it. Is your tank above (a platform) or below floor level?

Is it the connection threaded? My 71 is. Is the connection cracked or the tank itself. Maybe you can get a new connection.
