Haws Corp. has introduced Model 6519FR, a freeze-resistant valve designed for outdoor drinking fountains. Model 6519FR is designed to eliminate freezing standpipes above the frost line. It is equipped with a gravity/pressure activated piston. When the faucet is off, the piston drops down by gravity, allowing water in the standpipe to drain into a below-frost- line sump chamber. The water is expelled to the bubbler once the faucet is activated.
