Drains connected. This is how I did it. I did not put in a vent yet. I am going to put up with some drain gurgling until I decide whether or not I am going to add another tank and RV toilet. I'll vent it then if I decide to put it in, or I'll just vent this tank. If I do vent it, I may l just replace the T Pipe going into the tank with a 4 way and run a pipe to the corner and up the wall and out the roof. Why not cut another hole... right?
The stubbed off Pex is for future expansion.. Thinking I may add diverter valves to put shower straight onto the ground in remote areas. Just need a small ball valve just after the T before the tank (to close) and then another to open on the Pex leg. I will Will hold sink water in case of any food stuff.
