adding to the mix a little more ... Sealand/Dometic recommends against using alcohol based antifreeze in the vacu flush systems because of damage to rubber parts. If using the little more expensive Propylene antifreeze means I don't have to change duckbill valves quite as often then that's what I'm using.
