2025-28 - Fire Hydrants & Extensions

Fire hydrants shall be manufactured to the latest design in accordance with the current AWWA standard C-502. 

1. The hydrant must be a dry-barrel hydrant with compression shutoff.
2. The hydrant top section shall be red.  The bonnet and nozzle caps shall be white.  The caps must be secured to the hydrant barrel with a metal chain having links not less than 1/8-inch in diameter.
3. The hydrant shall have a 6-inch, standard mechanical joint inlet.
4. The hydrant shall open against system pressure when the operating nut is turned counterclockwise and close with system pressure when the operating nut is turned clockwise.  An arrow and the word “OPEN” shall be cast on or near the top of the hydrant bonnet.
5. The hydrant shall have one 5 ¼-inch pumper nozzle and two 2 ½-inch hose nozzles with National Standard Hose threads.  The nozzles shall be field replaceable utilizing straight threads or quarter turn seal by an O-ring. 
6. The hydrant shall be designed such that the operating threads are prevented from coming in contact with the service water.  The operating threads shall be contained in an operating chamber and sealed by O-ring at the top and bottom of the chamber.  The chamber shall be constructed so that grease or oil lubricates the operating threads and shall have an oil fill or grease fitting to facilitate scheduled maintenance.
7. The operating nut shall be 1 ½-inch in size and pentagon in shape and of one-piece construction.
8. All operating parts including operating nut, hold-down nut, drain ring and seat ring shall be all bronze.  The valve seat ring shall thread into a bronze insert or drain ring to provide bronze            to bronze seating.
9. The hydrant shall be simple and economical to install and maintain.  The hydrant shall not incorporate parts requiring field adjustment for proper operation.

10. The hydrant shall be designed so as to permit the removal of all working parts from the hydrant through the barrel without disturbing the earth around the hydrant.  The bury depth of the hydrant shall be four feet (48 inches).
11. Removal of the working parts of the hydrant shall be accomplished by using a seat wrench which can be used regardless of hydrant bury depth.  Hydrants requiring other special tools to perform removal of interior parts will not be accepted.
12. The hydrant shall have a traffic breakaway feature.  This shall be accomplished by the use of a split safety flange design.  Breakable nuts and bolts are not acceptable.
13. The hydrant shall incorporate the feature that allows the upper barrel to be rotated 360 degrees in order to assure proper nozzle placement.
14. Only bolted flanged components can be utilized during the assembly of the hydrant.  The bell or shoe inlet shall be 6-inch standard mechanical joint complete with accessories (to include at a minimum MJ gaskets, flange, and nuts and bolts).
15. The drain valve shall assure quick and complete drainage of the hydrant and the drain hole should be bushed with waterworks bronze if passing through cast iron.  The drain valve facing shall be made of buna N, nylon or urethane.  Leather facing will not be accepted.  If the valve top plate should come in contact with the bronze seat ring to facilitate draining of the hydrant, the valve top plate shall be made of bronze.
16. The main valve opening shall not be less than 5 ¼-inch, and the seating of the main valve must be made of bronze to bronze.
17. The fire hydrant shall have permanent markings identifying the manufacturer by name, initials, insignia, or abbreviations in common usage and designating the size of the main valve opening and the year of manufacture.  Markings shall be placed to be readily discernible and legible after hydrants have been installed.
18. Bidder shall furnish complete drawings, including parts listings and repair kit listings.  Each of the hydrants specified in the bid document shall be locally represented by a reputable, wholesale stocking distributor.  The fire hydrants and standard parts such as extension kits, traffic repair kits, and main valves, shall be readily available from local inventory.
19. Bidder shall furnish complete flow data on proposed fire hydrant indicating friction losses through hydrant which shall meet or exceed AWWA C-502 requirements.
