View Full Version : Freeze Protection of Backflow Preventers

12-06-2010, 08:04 PM
I have to winterize a few dozen 2-inch Febco 825Y reduced pressure zone backflow preventers (BFPs). The employer's budget will allow either (1) installing a proper, resilient-seated shutoff valve and drain system (this is absent right now) on the inlet piping; or (2) electric power to the BFP enclosures so heat tape may be used. I know both should be done. But the employer has said, "We can afford only one for this winter. Which is the better bet for both the short and long terms?"

if this is not moved, it should be in the irrigation area

Pardon my mess-up. I finally found the irrigation forum and re-posted there. Moderators, please delete this thread.
