Plastic-flavored sap

[highlandcattle]

We live totally off grid. Try online for low cost microturbines and solar panels. You will be surprised how cheap! We run our entire small farm, including the sap house this way! Regular deep well pump, homeoffice, flat screen tvs and my hubby is relaxing after a hard day in the woods(first year with tubing and vac), no bad taste, just great syrup)watching satellite tv. We have already arranged with friends for tube washing. Good luck.

Any other folks noticed this plastic taste in other brands? It seems Leader's 30P is the only one having this problem right now.

Any ideas for Lapierre, D&G and of course IPL?

Noticed it in our sap. Black tractor supply 1'' mainline.

I have Lapierre, potable water, D&G, IPL and Leader mainlines. Didn't have off taste last year, but this year only first 15gal of syrup.
Not last year probably because we missed the first run of sap.

I highly doubt taste is caused by sap in pipes in the bush...
