This was a two check pressure vacuum breaker assembly. It was produced from approximately 1975 to 1988. The 3" and 4" checks are the same as the Model 805 with an air inlet mounted on the second check cover. The 6"-10" uses the same check design as the 805 Y. The air inlet is the same on all sizes and is the same basic design as the air inlet of the 2" Model 765.
