I found the barb piece at HD, what I couldn't find was the piece of CPVC that goes over the barb onto its housing. I understand you have to cut out the center and you use the thread on the other end to screw on the WD bottle. Is is just CPVC pipe, what about the thread. Tough day for me.
What is the piece that goes over the barb? What is is called beside piece of 1" Drinking water quality PVC ?
