How to Size a Backflow Enclosure

Start by measuring the full installed assembly — including the backflow preventer, shutoff valves, test cocks, strainers, and any unions. That total measurement is your minimum inside clearance need. Then add at least 6 inches on each dimension so technicians can reach test cocks and perform annual testing without having to remove the enclosure.
