Simmons Genuine VB75NL Vacuum Breaker

The VB75NL vacuum breaker can be used on any Simmons residential standard hydrant. The threads on the breaker are standard hose thread. The VB75NL is not a self draining vacuum breaker, which means you will have to manually drain it to prevent freezing. You can do this by pushing the piece in the bottom side of the breaker over. This will create an opening for the water to drain out.
