Up until now I had used 3/8" ID tubing throughout my all grain system.
Recently I upgraded my false bottom for my 10 Gallon Rubbermaid Cooler with 12" stainless false with Brass Elbow that came with a 3/8" barb (seems to be the standard). It attaches to a new ball valve cooler adapter 1/2 MPT with 3/8" barb inside the cooler and 1/2" barb on the exterior (the 1/2" exterior barb on the ball valve also seemed to be the standard).
My question is that I had assumed I would go to 1/2" ID tubing on the outside of the Mash Tun. I have 1/2" output barb on my boil kettle and 1/2" input and output on my plate chiller.
Why would everything be setup for 1/2" tubing but the interior line from the false elbow to the input of the ball valve be 3/8".
I looked around on the net and in some forums but could not find anything that talked about if I should be concerned about having a smaller line inside the mash tun then the 1/2" barb and ID tubing outside. Maybe it doesn't matter? or maybe 3/8" is max flow I would want anyway?
Anyone have any thoughts on correct sizing and positives and negatives of tubing size or starting smaller then changing sizes,etc.? Thanks
