Roof Hydrant
Model RHY1-MS
The patented Woodford RHY1-MS is intended for irrigation
purposes and to provide water availability on commercial
building roofs. Applications include window washing,
cleaning of condenser coils, cooling towers and other
types of roof equipment. The hydrant valve body is drilled
and tapped with 1/8” drain hole which must be piped to a
drain location.
The RHY1-MS allows for installation exibility since it is
not necessary to install hydrant when hydrant support
is mounted to the roof. The hydrant support utilizes a
3” opening that allows the hydrant to be installed later
if desired. All necessary mounting hardware for proper
installation on a commercial roof is supplied, including a 2
degree shim for pitch adjustment.
Hydrant Features:
• Rod guide eliminates side pull on rod, reduces
wear on packing, packing nut & stem.
• Adjustable link for easy adjustment and positive
lever lock tension.
• One piece variable ow plunger with large cushion
type seal for longer life is not easily damaged and
assures shut-o󰀨 even when foreign particles are present.
• All hydrant repairs can be made from top of unit
without removing hydrant. Parts are readily available.
