Roof Top Pedestal Hydrants:
** NOTE TO SPECIFIER ** The dome handle enables the user to operate the valve assembly while preventing rainwater from entering the enclosure. The hydrant utilizes the best of the Nibco globe valves within a fully insulated stainless steel shroud. The "drain down design" of the MPH-24FP hydrant operates on the venturi principle and is a cooperative effort based on the design of the sanitary yard hydrants manufactured by "Hoeptner Products." When the hydrant is OFF, the stopper seals against the nozzle and stops flow. The water remaining in the riser drains back into the reservoir tank below the roofline. When the hydrant is ON, the flow through the nozzle creates a vacuum in the reservoir evacuating the water out through the hydrant. A brass valve float assembly located on the stainless shroud allows air to escape from the reservoir as the tank fills and allows air to enter the tank as the vacuum force evacuates the water from the tank. A quick disconnect provided allows a hose to be readily removed when not in use so as to insure proper evacuation of the reservoir during freezing conditions. The Under-deck Flange prevents the Hydrant from becoming dislodged from the roof membrane during operation. The Weather-Guard Domed Handle prevents moisture from entering the assembly when the valve is in the OFF position. Supply connection is made at the 3/4 inch (19 mm) fitting located at the base of the Hydrant. The unit is provided with an under-deck support flange and mounting hardware. This flange when secured to structural angle supports at the roof deck will prevent disruption of the roof flashing during normal operation. Refer to installation procedures for specific instructions on installing the hydrant. Hydrant is also available for use in landscapes where the stainless base and under deck flange are omitted and replaced with an anchoring collar allowing the hydrant to be securely located in the ground. Delete if not required.
