As the title says, I'm getting an odd oily taste. I washed the tube and plungers with hot soapy water before assembling. It starts out good but now that the juice is gone down by half.. I'm getting an odd taste, like coming from the syringe and plungers. A "machine" or a "plastic" taste (not the burnt plastic from a burnt carto) I've read so many good things about these tanks and couldn't wait to try one. The only thing I've read about it giving a bad taste is from someone who didn't wash the parts before using. I'm really down about this. This thing works wonderfully! No leaks and it's so easy and cheap to make. Drilling and tapping a hole is so much easier than the polycarb tubes and my nylon screws fit nice and snug with no air leaks. I know the syringes come packaged with some sort of lubricant but I figured washing would take care of that. I also washed the screw. When I first assembled it this morning, after using it for awhile I started noticing the taste. So I took it apart, washed it, and put in a fresh carto and now it's giving off the same taste again. It's not my juice.. it's the same mix I've been using in my polycarb tanks (with vinyl grommets) and I never got even a hint of this taste with that. Also, I'm using the "ideal industries" brand everyone else uses. Am I the only one? Any suggestions?
