The Model 805 is a double check assembly. It was produced from approximately 1979 to 1988. The body is of bronze construction and utilizes an in line check design. Check seats were cast into the body and were not replaceable. Check springs were contained when the cover was removed but the spring tension had to be released for proper repair. The 3/4"-1" internal hardware parts are mostly plastic. The 1 1/2"-4" internal hardware parts are mostly bronze. The 3/4"-2" size had check covers that screwed into the body.


Common repair parts are a very small subset of the 10,000 plus items BAVCO stocks. Please feel free to contact us direct at 800-458-3492 for pricing on items not listed or backflow prevention devices.
