Another thing: your drain lines from the tank(s) should be larger than 3/4". A 3/4" line will take a very long time to drain. Standard RV bayonet fittings are 3" fittings. From a gray water tank, the drain line doesn't need to be 3", a 2" or even 1 1/2" line would likely be sufficient.
If you don't use a normal RV hose and connector, you'll probably have some trouble hooking up easily to dump stations that require the use of a donut or other seal on the sewer line. The bayonet fittings are also a lot quicker and less fidgity to hook and unhook than a garden hose screw connection.
Ok I understand 3/4" diam. is to small, how bout a flexible pool vaccum hose, they are 1-1/4" diam. they're light, cheap, quick connect. I saw many types of adapters on ebay/amazon for bayonet type connection, maybe I can add one at the end to connect to the camps site sewers?
The pump outlet is 3/4" diam. I think I can't oversize that one, or else the pump would fail to lift the water over the center aisle, right?
