Just a follow up on irrigation pipe v ethanol debate
From what I can tel both Moss and Toro/Pope use polypropylene(PP) Pipe
and fittings. I then did a search on polypropylene and this is what
had to say.
"Generally speaking, the chemical resistance of polypropylene and
polyethylene is considered superior to that of metals. They are
unaffected by most inorganic acids, alkalis, and aqueous solutions which
rapidly corrode metals, although some concentrated acids and oxidizing
agents can attack them, especially at elevated temperatures. "
they then had a chemical resistance list and ethanol come out OK. Unless
I have missed something somewhere the irrigation pipe that Im using
might be ok. Im going to set up a little test vial with some 85% ethanol
and a piece of plastic and see what it does.
