*****PRIER's 400 Series hydrants are the current "half-turn" lawn faucet with a vacuum breaker cap above the handle. This valve was originally the "Mansfield 578" hydrant (multi-turn) that was made by the Mansfield Plumbing Company in Perrysville, Ohio. While PRIER has service parts for the original Mansfield 500 Series valve, it is no longer manufactured. The PRIER 400 Series lawn faucet (half-turn) is now made by PRIER in our Grandview, Missouri plant. It is a simple operating product and is fairly simple to repair.
