What are the modern/standard fittings for fresh and black tanks?
Given I am decent in composites I was thinking of building my own water and black water tanks, was it the standard fittings?
* For the fresh water tank I see the water pump I ordered takes 1/2, fittings so I was thinking of running 1/2 PEX. For the breather hose I assume I can use 1/2" PEX, for the line to fill it?
*For the black water tank, I assume I cut out the dimensions for the toilet to mount to. Use a 1/2" breather hose (too small?). For the outlet do I need a three inch fitting such as Uniseal Slip Fittings
I read somewhere about the waste water tank drain line screwing on, and it appears from the link above it is just a straight tube that comes out. Is there some other kind of fitting? And do I need another fitting where I ran rinse it out, or just use the same line that it drains from?
*For a grey water tank do I need another three inch outlet, or some smaller unit?
