I know PVC is not the preferred material for a glycol loop but is it really that bad? I was planning on using Aquatherm, and I still might if the price isn't too much higher than SCH 80 PVC. I'm designing, sourcing, installing, insulating, and maintaining this loop myself and I'll most likely need fittings that I didn't think of in the design. It will be easier to get PVC fittings at one of the 4 nearby stores in just a few minutes but it might take 2 days to get the Aquatherm parts from the one supplier that's 30 min away and doesn't keep much inventory. I spoke to someone in my area who has been designing and installing glycol systems for brewerys for 12 years (there are a lot of brewerys in my area) and he only uses PVC and said some have been in service the entire 12 years with no issues. He did admit that SCH 40 does get brittle after several years and cracks when cut making repairs and expansion dificult but he's had no issues with SCH 80. Also, what size supply and return should I go with 1.5" or 2" for one 10BBL and four 7BBLs? I also want to be able to expand someday, possibly up to five 15BBLs. How do I determine what size pipe to use??
