Thinking about trying to repair my black tank's flange adaptor

My renovation is just getting started and already I have had a few surprises. I'm considering trying to fix my black tank. It looks like the input hole just broke off at some point. Whoever "fixed" it had the toilet just pointing into the hole you see in the top of the tank... no seal whatsoever... gross.

I'm considering cutting a round hole in one of these: Plastic Sheets |

Then attaching the receiver for the flange.
Then I'm thinking I can weld it to the original tank so the flange receiver is in the right spot and so I seal the tank. It seems like it's worth a shot for $20 vs. buying a new tank.

Anyone else tried this?

I think the cost of a new black tank is money well spent, considering the amount of work it is to access, remove and install.


Work is never done, so take time to play!

Looks like the same blue plastic as my first Fresh Water Tank. I tried to reuse it and it cracked on the first trip. I am so thankful it wasn't the black tank that cracked!

I agree with the rest. I'm making my own black tanks. It's just not something you want to do twice. You're already there, spend the money and do this part right. Anything else you could probably skimp on, but not the tank. Check Vintage Trailer supply. Your other option is to go with something smaller, but that will still fit in the space. I'd rather have a smaller tank, than a tank I have to worry about.
