I found food grade mag pumps that are plastic on line.
One of the reasons for food grade pumps it to be able to handle boiling fluids.
Who on earth is going to run boiling fluids to their plants.
I find the whole organic certification program lacking in common sense and an organization that hauls in tons of money every year but yet claims to be non profit.
As for a pump for the house I wouldn't worry one bit about whether or not it is food grade to run fertilizer to plants.
The same thing happens with curing/brining meat and fermenting food.
They say dont use metal containers.
This is total BS but they have dumbed the information down so some idiot wont go out and do it in a tin can or galvanized wash tub.
