Greetings,
I am researching and purchasing the parts for a new installation and currently working on the valve manifolds. My research has led me to believe the common method of converting from PVC downline of the valve to the poly is with a PVC to poly adapter (slip or threaded x barb).
My concern is that the barbs I have found are reducing from 1" on the PVC side to 3/4" on the poly side (obviously - the barb needs to fit inside the 1" polypipe). Does this now effectively create a 3/4" flow rate for the system downline of the valves? The adapter I currently have purchased is from Lowes: LASCO 1-in Dia PVC Sch 40 Adapter (

If the system is actually effictively 3/4" due to the barb adapter, is there a better way to make this connection? My system will be 1" for the entirety of the lines and valves - from the well through the laterals.
