And as mentioned in a different manner- after draining, open the bottom valve, lift a bucket of AF solution up around it, reach in and shut the lower valve- frost proofing. Doubt the flammability matters if the brass in the valve melts and allows the solution out in advance of water from the DPV. After water arrives, massive dilution.
Maybe not politically correct, but your service techs get more sleep at night. Course this is looking to lower the cost of ITM, which may or may not be your goal. George L.

From a design side, making sure they can find and readily access all of them and they are shown on your plans as per current editions (24.6.2(13) 2010 ed) is also time well spent.
