Black Water Tank

[alstude]

Has anyone ever experienced their blackwater tank bulging at the bottom?

Yes, mine does, it makes it hard to clean out. I'm looking to see if there is a way to add a support.

I think there is a way, and I am having two supports made from angle iron which can be bolted to the angle iron supports that hold the tank on the frame of the trailer. Once I get them installed I will be happy to share the plan of them.

Yes, I'd like to see what you come up with when you get it done.
Thanks

Mine, too, sags a little, but, I don't worry too much about it. A little water left in the bottom (most of that water is "fairly clean" from the flushing process) sloshes around while driving and helps to scrub the tank and keep soft anything that my flushing might have missed. The black tank is not something that I'm too terribly concerned with having absolutely empty after I dump...the flushing takes care of the waste and any water left is mostly, just that, water.
