I picked up a used Mason 2x3 that had been extended with a additional 2x4 rear pan during the off-season. The previous owner used a siphon system to move sap from one pan to the other, but I'd like to get away from that method and go with a more common approach.

While checking out evaporators during a recent trip to Bascom's it looks like most of the small evaporator pans are using 1" and larger pipe to connect to each other. Would 1" be appropriate for the application or should I go larger? I'd love to use sanitary fittings, but their cost is so much greater than threaded pipe and fittings that I think I'm going that route instead.
