if i might join in here with some clarification questions,
-the tank must have 1. a primary reg and 2. a secondary regulator, right?
-a line can be run to more secondary regulators. If there are 2 secondary regs, then 2 separate pressures can be obtained. If 3 regs, then 3, ... right?
-can you run a splitter to the first set of regulators, straight from the tank, allowing access to 3 separate pressures even if only 2 additional regs are there? Is the question clear?
-are there any advantages to storing the tank inside the kegerator/fridge, besides aesthetics?
