Black water tank

Hi all, I have a 2013 Econ 14BB that has a 10 gallon, yes ten gallon black water tank. That is really small. Has anyone had the experience of replacing a black water tank with a larger one? If so, how hard was it?
  • Problem with going larger is 'AVAILABLE' space to install larger tank.
  • It is likely possible, but will require some planning. I added a gray tank to a 1970 RV. As Old Biscuit said, available space will determine what you can do.

    Once you figure that out, look for a tank. I found a roto-molding place not too far away that built a tank for me. They do custom tanks if needed, but one of their existing sizes worked (in my available space!) - I just had to tell them where to put the inputs (drain & vent) & output.

    You'll need to figure out how to attach/support the tank too, and if any plumbing changes will be needed.

    Was definitely some work, but worth it in my case!

  • Ours is 15 and it took my family of six three days to actually fill the tank. If you really ponder the volume ten is enough for most. I also discovered the bathroom sink goes into black probley just for volume? Forget the guages. They are liers much like politicians.
