Tanks

[Melbo]

I had my tanks custom built out of hdpe and had all the openings installed where I wanted them (look in the yellow pages under plastic welding or plastic supply). I had the black and gray tanks made lower profile so I could install the drains into the top and the fresh tank taller because I only need to fill it. I also installed vents in the top of all three tanks (because I could have all the openings I want installed) the fresh and gray have baffles and the black does not.  I used "CT" connectors to connect all the drains vents and assorted piping so there is a little flex in every run. I also planned the "CT" connectors so if I disconnect them all the tanks will slide out and leave the rest of the plumbing in the coach. I'm sure because I designed that way I will never have to take them out. I installed a lot of passive vents in the system so it could breath. Just my way -- good luck with your search for tanks.

I'll Ditto Melbo  (is that legal )

Mine were not installed that way and I need to replumb it now, there will be some connectors next time.

Get some lean toward the drain too
