Haws freeze-resistant bury valve for use with dual bubbler head pedestal fountains shall include dual brass pneumatic operated valves installed below the frost line, check valve to drain water from unit when not in use and to prevent back-flow cross contamination, regulator valve, separate valve access and pull-out design for easy maintenance, 6-inches diameter PVC pipe to encase valve assembly, and 1/2-inches IPS supply. For use with models-3150FR, 3300FR,3500FR, 3511FR-Sold Separately. Operation and maintenance ease is achieved through both the adjustable stream regulation and the ability of the valve assembly to be lifted to the surface and lowered back into the casing, so in the rare event that maintenance is required, can be done without having to disturb the fountain. Reliable and fully engineered system allows for two pneumatic valves to be installed below the frost line, and equipped with the ability to drain the water line after use to non-freezing depths so the unit can be used year round. Installed below the frost line, the valve remains fully functional under the worst of weather conditions, with the fountain remaining functional as well. If a maintenance issue ever arises, rest assured that the valve assembly is easily removed and replaced without disrupting the remainder of the fountain. Flow is easily adjustable with supplied regulator valve. Unit is applicable for dual pedestal mounted fountain designs.
