So many interesting arguments for this crazy topic I started. Yep its my fault. I have eaten cheese made in it with no bad flavor. I too checked with my BIL, and he too said pvc for water. And some water remains in the pipes at all times, so if there is any leaching happening, you all better quit drinking water from the tap. We had our water tested for the milk processing facility, also thru pvc, and it tested negative for everything. No lead, no chemicals, no nothing cept a little iron from the shallow well. We passed with flying colors so.... I guess this was the thought behind the pvc. It clear many of you disagree. I will eventually get the other molds, but only because they are lighter and thinner. I matched the hole pattern and my cheese drains real well. Sorry.... Guess I'm cheap and irresponsible....
