Commercial Roof Hydrants

Freezeless Roof Hydrants are designed to facilitate a secure, exterior water source installation on commercial roof surfaces. The hydrant is installed through the roof and plumbed to the non-freezing interior water source. The hydrant is supported by a heavy duty cast iron (MS) Mounting System. All necessary mounting hardware for proper installation on a commercial roof is supplied, including a 2 degree shim for pitch adjustment. Roof Hydrants are specified for washing condenser coils, windows, cooling towers, green roofs and other types of roof top equipment.

Order a complete Hydrant with Mounting System or individual Hydrant or Mounting System units.

  • All hydrants are operated by lifting the lever handle.
  • All repairs can be made from the top of the hydrant.
  • The patented RHY2 features a built-in vent that allows automatic draining when hydrant is shut off, even with a hose and device attached. An 1/8" NPT drain line must be piped from the tapped valve body to a drain location to prevent freezing.
  • The ASSE 1057 SRH Sanitary Roof Hydrant requires NO drain line. With hose removed, a venturi action draws water out of the internal reservoir and discharges through the outlet.
