Real comment. No way that is any way food grade if that is a roll cart trash can.
We each have to make are own decisions in life as to the risk we are willing to accept. I have 35 years now experience in analytical chemistry. First 5 years I worked for Shell Research in Houston, TX doing analytical chemistry trouble shooting on plastics of all types via optical spectroscopy methods. I learned quite a bit about all the various types of plastics, additives, plasticizers, reasons for additives, slip agents, mold release agents. These things won't kill you overnight but they were not meant to be ingested either. Something that is not made to be in contact with food has a completely different (cheaper ) manufacturing process than something that is made to be in contact with food.
As winemakers you should never forget that you are working with not only an acidic liquid but at the end of the process a 12-14% ethanol solvent. The combination of low pH and a solvent in contact with plastics will have consequences over time if that plastic was not intended to be in contact with that type of liquid.
So while PVC pipe may work well with water, pH ~7 unless that pipe was formulated to be in contact with a low pH acidic solvent (wine) you run the risk of it stripping off those slip/release agents, plasticizers etc that they were not meant to come into contact with or soaked in.
Many of these additives are low level carcinogens. When I was working with these things I was in a OSHA regulated carcinogen monitoring plan where I had my blood monitored once a year for them.
Use caution, do your homework and for your own safety and peace of mind use the right materials in everything you do be it your job or this crazy hobby we all somehow found ourself getting into.
And @ibglowin, are you messing with JohnT or is that a real comment? I'm just asking out of curiosity. I'm not playing games and will be picking up another legit brute
