This was a pressure vacuum breaker. The unit was produced from approximately 1950 to 1975. It was a bronze bodied unit. Most internal parts are made of bronze. The assembly was not in-line repairable and had to be disassembled to repair it. The original model numbers were different for each size. Some may still have these older original model numbers on them: Model 610: 1/2" and 3/4", Model 620: 1 1/2"-2" size. The spring was not contained when the body was disassembled. The seats were not replaceable.
Common repair parts are a very small subset of the 10,000 plus items BAVCO stocks.
