    Default Chinese RO membranes

    Has anyone tried the Chinese ro membranes that are available on Ebay? Are they any good?

    I'm sure the Chinese ones would work. I'm sure all the big name brand membranes are made in China as well.
    But for the price you can get them here for example at MES. I think its $230 for a 4" and $800 for an 8" it's not worth experimenting with an unknown Chinese membrane.

    I don't care where they are made, why would you buy something and take a chance on it working? Our windows are short to make syrup. Down time is a killer in this business

    Not to take a side, but it is probably because dealers have to cope with this issue all the time. People try to save a few $, then when they got from some cheap supplier fails, they have people beating on their doors trying to get them to fix the problem immediately. Kind of like buying after-market engine parts for your car and then complaining to Ford when the piston blows out.

    I tap 35ish trees. If ro doesn't work I would be able to boil what I collect. I was just looking to save some time without spending a ton of money but I guess the cdl sales reps seems to think it'll fail

    With 35 trees, you're probably better off looking into a micro-RO rather than a true maple RO unit (which would cost far too much, the membrane is just one part of the total cost). These are the off-the-shelf, undersink type units. They are slow, but do work. Cornell has some info/videos on them.

    I'd like to think the CDL rep was giving you some good advice regarding what the consequences may be If it fails. Will the EBay seller be able to get you back up and running as quickly as a local dealer or supplier...
    I don't think he knew that - in your case - you could do just fine without the RO.
