TRAFFIC REPAIR KIT

EXTENSION KIT

Inspection Upon Delivery

• Inspect hydrant prior to installation in order to check for damage during shipment.
• Hydrant should be operated to full open and close positions to ensure that it has not sustained any internal damage and that its components are intact.
• Hydrant should be pressure and leak tested before installation due to the tendency for nozzles and hardware to loosen during shipment.
• After pre-installation inspection and testing is completed, close the hydrant main valve and replace and tighten nozzle
• In the event that storage is necessary, the hydrant should be stored with the inlet face down. Reinspect just before installation.
•  Refer to the “Hydrant Installation Detail) for an illustration of the completed procedure.

Installation

1. Coordinate Hydrant installation with water mains appropriate for fire flows.
2. Hydrant must be installed as plumb as the conditions will allow.
3. Installation location must be in accordance with local fire code, fire authority, or municipal design standard.
4. Unless otherwise specifi ed by local fire code, the recommended setback is a minimum of 2 ft. from the curb face to the nearest point on the hydrant.
5. Align the face of the pumper nozzle towards the street so that quick connection can be made to the fire pumper.
6. Outlet nozzles must be installed a minimum of 18 in. [46 cm] above the ground line for adequate operation of the hydrant wrench. No obstructions to the removal of nozzle caps or hydrant operation are permitted.
7. A hydrant gate valve (auxiliary valve) must be installed on the hydrant lead between the hydrant and the water main to permit isolation for maintenance and emergency shut-off purposes. A joint-restraining gland or other thrust restraint should be provided so that the hydrant can be sufficiently removed without shutting down the main.
8. Remove any loose or foreign matter from the hydrant lead before installing the hydrant gate valve and hydrant.
9. The hydrant gate valve should be installed as close to the main as possible.
10. Set the hydrant using a solid footing such as stone slabs or a concrete base in order to prevent settling and strain on the hydrant lead and water main. A jointrestraining gland or other thrust restraint should be provided.
11. When the thrust block is to be poured, do not to block the hydrant drain holes.
12. Install traffic hydrants according to local fire code and AWWA Manual M17 requirements; accounting for appropriate soil resistance, PVC mains, frost penetration, adequate drainage, high water table, etc.
13. The drain outlets must be plugged in areas where the water table is high, and the hydrant must be appropriately marked and pumped dry after each use to avoid freezing.
14. Do not connect drain outlets to sanitary or storm sewers.
15. Hydrants installed on an existing main should be disinfected before installation. Follow typical disinfection procedure, using AWWA Manual M17 as a reference.
16. If additional foreign material is a concern – before disinfection – remove the valve and valve seat from the hydrant and flush the main through the hydrant by means of the hydrant gate valve control.
17. Please refer to the AWWA Manual M17 and AWWA C600 for pressure testing requirements and further installation details.
18. For general Field Disassembly and Reassembly see instructions below.
19. For Safety Flange Repair please follow instructions below for Repair Kit #F-06-301.
20. For Hydrant Extension kit please follow instructions below for #F-06-320.

Hydrant Illustration Detail

Maintenance and Repair (Disassembly and Reassembly)

1. Close hydrant gate valve in order to stop water flow from water main to the hydrant.

2. In order to relieve any standing pressure,remove one of the hose nozzle caps (#21) and open the hydrant three full turns.

3. Loosen and remove the hold down nut (#4) and operating nut (#1); do not misplace the anti-friction washer (#6).

4. Using United FIREFLO Hydrant Lubricant #F-06-51, lubricate the external diameter of the brass sleeve and thread it onto the threads of the upper rod (#11). This procedure will protect the bonnet o-rings (#10) from damage from the threads of the upper rod while the bonnet (#8) is removed.

5. Remove the bonnet (#8) by first removing the bolts & nuts (#9) and then gently lifting it off of the upper standpipe (#24). Remove bonnet o-ring (#10) from the upper standpipe flange groove.

6. Unthread the brass sleeve from the upper rod. Place the seat wrench flange (3-branch centering device) over the stem and insert the seat wrench (T-handle) through the hole until the slots engage the stem pin (#33). Tighten the thumb screw and loosen the rod assembly by turning the seat wrench counter clockwise. Seven full turns should adequately disengage the assembly.

7. Remove seat wrench and seat wrench flange. Carefully lift the rod assembly from the hydrant.

8. Flaten the lock washer (#48) and remove the valve components: valve bottom plate nut (#49), cap nut seal (#47), valve bottom plate (#46), main valve (#45), and seat ring (#43).
   Clean, inspect, and replace any worn or damaged parts.

9. Inspect the drain valve facings (#34) for wear or damage and replace if necessary.

10. Inspect o-rings (#39 and #44) on the seat ring (#43) and replace if cracked or split. Before reassembly, lubricate the o-rings and threads with FIREFLO Lubricant.

11. Reassemble the valve components according to the order in which they were disassembled. The valve bottom plate nut (#49) must be tightened to approx. 100 ft-lb. Bend the lock washer (#48) over one edge of the valve bottom plate and over an opposite edge of the valve bottom plate nut.

12. After reassembling the valve components, replace the rod assembly by lowering it into the hydrant barrel. Take caution not to damage the o-rings while lowering the assembly. Use the seat wrench and seat wrench flange to tighten the rod assembly to 375 ft-lb.

13. Apply some FIREFLO Lubricant to the bonnet o-ring and install it into the flange groove of the upper standpipe.
    Check for appropriate lubrication and thread the brass sleeve onto the upper rod and reinstall the bonnet and bonnet bolts without fully tightening.

14. Unthread and remove the brass sleeve from the upper rod and bonnet.

15. Reinstall the operating nut and anti-friction washer. Before installing the hold down nut, inspect the oring and replace if cracked or split. Apply some FIREFLO Lubricant to the o-ring and install the hold down nut. Tighten the hold down nut and the bonnet bolts and nuts.

16. Unthread and remove the oil plug. With the hydrant in the fully closed position, fill the oil fill hole until the oil just begins to run over. Caution: do not insert oil unless the hydrant is in the fully closed position; otherwise, the chamber may become overfi lled – resulting in a pressure lock which can damage the o-rings and other components.

Nozzle Replacement

17. Remove the hose nozzle cap (#21) from the nozzle to be replaced.
    Using the United Nozzle Lock Key (#13) Installation Tool and a standard claw hammer, remove the nozzle lock keys. Place the nozzle wrench over the nozzle so that the wrench slots and the nozzle lugs are properly aligned.

18. Replace the nozzle cap and hand tighten to the face of the nozzle wrench. This will effectively hold the wrench in the proper position.

19. ( Slide a 3-ft. piece of galvanized steel or black iron pipe (2” Schedule 40 min.) over the end of the nozzle wrench to gainenough leverage to loosen the nozzle. Loosen the nozzle in a clockwise direction (left-handed threads).

20. In a counter-clockwise direction, thread the new hose nozzle and o-ring (20) into the upper standpipe. Add the nozzle wrench and cap as specifi ed above, and tighten the new nozzle to 600 ft-lb. Remove the wrench and cap.

21. Using the nozzle lock key installation tool and a standard claw hammer, drive the nozzle lock keys between the lugs and the inside diameter of the nozzle recesses. Ensure that the nozzle lock keys are centered lengthwise with the nozzle lugs. Conduct standard leak test procedure.
