Building a one barrel system and wondering what size fittings I should be using. Thinking 1/2" will be too small. Thinking closer to 3/4-1 inch. What say you?
I know that more beer has the pumps with the 1" inlet and 1/2" outlet. Not sure says they are 17gpm, just have to use an adapter to go to 1" on the outlet.
Im using 1/2" hoses and fittings on my 1bbl system with march pumps and it works fine. Unless you replace your pumps, they will be your bottle neck. I personally dont think a 300-500 dollar pump is worth shaving a minute or two off your transfer times.
However, when i switch over to tri clamp fittings, i plan on using 3/4" barbs for my hoses, that way everything should have at least a 1/2" bore.
