I found that all 3 valves were in fact, 3" valves. It makes since as the dump ports are 3" and going from a 3" port in the tank to a 1.5" reducer and then back to 3" would be overly complex.

I will be installing the Barker Auto Drain valves this weekend. I would like to combine all to a single dump port, but I am not sure that I could get the pipe to run over the axles. Even if I drop it to 1.5" from the galley tank.
