    Btw, quick update on this. I've gone ahead and ordered the valves only (no backplate since I'll be doing a full custom install) from Anderson Brass, It'll be a few weeks unfortunately until they're able to ship but once it arrives I'll be able to get a closer look at it and start prepping for how I want to install it.

    I ordered an extra main Inlet check valve since for my my unit I need one for my main fresh water and an extra for my black tank rinse in the general same location. Looking forward to this and it's small footprint.
    I'll custom make the panel once the valves arrive and I can see exactly where I want to mount everything.

      FWIW . . . an inlet check valve should NOT be used on a black tank flush system. For the flush line vacuum break to work properly and maintain sanitary isolation of the black tank, the water must be allowed to flow back out the flush inlet when the flush hose is removed. This leaves an empty line from vacuum break to inlet (and vacuum break to black tank), preventing any bacteria migration through standing water, which could be the case if water were held in this line by an inlet check valve.

        thank you! I will get and use a standard inlet without a check valve! I appreciate it. Makes complete sense

          Would there be that much to change when switching from the Nautilus to the Anderson? I have been thinking of doing this myself , because I am bored, and was thinking that it would just be an easy change over. Maybe I am missing something?

            Hi Brian,

            The plumbing system within the trailer is essentially the same whether the control panel is Nautilus, Kantleak or home built. All the inputs and outputs are the same. By the time you dissect the rats nest and begin an orderly connection of inputs and outputs, it won't matter whether the plumbing originally connected to a Nautilus or a Kantleak control panel.
