    PEX vs. Copper

    We are going to need to replace the main water line coming into our new production facility. We have quotes for copper line and PEX line and the copper is running about 5x the cost. We're a little apprehensive about "plastic" water line from both a standpoint of flavor and of any potential leaching of polymers that could pose flavor or other product integrity issues. We are also wondering about pex for building plumbing (post carbon filters).

    Does anyone have any experience or insights that might be useful?

    I am not familiar with the PEX term (trade name?) Can you define the actual material - is it polypropylene?

    Thumbs up Don't worry

    Hi,
    You don't need to worry about using PEX (cross linked Polyethylene) for your water lines. It will not affect any taste of the water and it will not leach any polymers. This material have been used worldwide for many many years and it will be more and more common here in USA also. In Europe this is the most common piping material for new house building and restoration of old houses. PE is also the most used piping material in Europe for water distribution in towns and country. It will not corrode and it have a very smoth surface. Remeber you have probably sometime bought drinking water in a bottle and that was probably a plastic bottle (made of PE=PET) did you have any problem with taste?

    Don't hesitate go for it.

    Best Regards,

    Dan

    Water bottles

    Are these the same water bottles that now have been shown to release carcinogens and endocrine disruptors like bisphenyl-A, styrene and DEHP?

    Hey Moon, I was under the impression that the only problem with plastic bottles was if they were reused. Do you have a source for more info?

    Heat/microwave can especially be a problem. Just park online for a few minutes. There are an assortment of views. Some people believe in global warming, too. Ever had your prostate checked?
    I am not questioning this piping material-just being pessimistic about the water bottle comparison!

    Plastics for making wine

    There are plenty of info on using plastics for making wine. Plastic is good for wine so for beer either.
