: In most areas, adding a backflow preventer is involved with the local water supply. If this is about a well system, then that isn't involved.

: Operationally, the backflow overcomes at least 40 psig, so vertical wouldn't be a pressure difference problem; but I'd call Honeywell to find out, as the drawings for the device show it only in the horizontal position.

: "Vertical installation of backflow preventers will be accepted if the device is approved by the State for that type of configuration. ..."

I called Honeywell and they were useless after it took forever to get through.
Comfort calc.com forum, states I dont need it for a low pressure steam system. I dont know. I may just install vertical and see what happens unless there are some other suggestions? Any new hlp is appreciated
