Merrill's Product Catalog: Frost Proof Yard Hydrants
The Merrill Any Flow® Yard Hydrant gives year ‘round water service; it drains below the frostline when shut off. The Any Flow® Hydrant has had only a few improvements since 1949. These improvements, the exclusive features and benefits, and the time-proven basic design, is why we believe the Any Flow® is the best yard hydrant
manufactured by anyone.
