Not buying any but my employer will be buying many gallons of the sticky stuff soon. Large warehouse. Employee ran a forklift up into a 6" sprinkler line and ruptured it.

Massive amounts of antifreeze all over their stuff.

Will get pics if I can.

Depends on if they're using full-blown auto antifreeze or RV antifreeze. I just bought some Prestone for my pickup at Wally World. It mixes with any other antifreeze and it was $10.50 per gallon.

Good to know I'm not the only person that refers to it as Wally World...:laughing:

You can't put ethylene glycol (regular car antifreeze) in a sprinkler system or a hydronic heating system.

True, we wandered a little here. Propylene glycol only. We paid 21/gal last time we bought some, last summer.
