The periodicity for such inspections should be determined and laid down depending on the local conditions. Brass parts should be cleaned and polished. such inspections for each hydrant should be carried out at intervals not exceeding one month and for industrial establishment once every week.3 The following action should be taken during rthe monthly/weekly inspections: The a> hydrant or valve pit should be opened and checked that it is clean and not filled with any dirt or leaking water. the water supply. it should be emptied and cleaned. If frost valves are fitted. indicator plates. Any blank caps’or covers provided on the outlet should be replaced and securely fixed. Close the valve slowly to prevent water hammer and a possible main burst. every endeavour should be made to avoid collecting water simultaneously in a pump from a drinking water main. The results of such tests should be recorded and remedial action taken where pressure and output fall short of the stipulated requirements. MAINTENANCE CHECKS AND . In the case of underground hydrants. if the hose is connected directly to a branch. 7.25 kgf/cms or higher. if necessary. if needed.6 Proper handling and working of the hydrants can go a long way in their better maintenance and satisfactory performance over long period. k) All cut off ( isolating ) valves should be operated and oiled. round the frame should be examined and a report made if these are damaged. 7. The following simple rules should be followed whenever hydrants are operated: b) The valve should be opened slightly to see that water is flowing freely and there is no obstruction in the outlet. The pits should be thoroughly emptied of f) water and cleaned before the covers are closed. Hydrant mains should be tested with the pump delivering at its maximum pressure with all the hydrants outlet closed and thereafter. The record of all such inspections should be maintained and remedial action for any defects observed should be immediately taken on priority basis.‘7 INSPECTIONS. 4 If any washers are used in the outlet. The practices should be so arranged that the maximum number of hydrants in different areas are operated in rotation. should be checked and removed. pit covers.2 Each hydrant provided in the area should be inspected as often as possible. the valves should be opened only after fixing the stand pipe and fully closed before the stand pipe is removed./” j) 7. water department engineers should also be associated. it should be checked that it is in position and securely fixed.4 Apart from the monthly/weekly inspections. if necessary.5 Testing of pressure and output in different areas covered by the hydrant system should be carried. During such tests. The stand pipe or hose should not be disconnected from a hydrant in which no water is available or from which the flow has suddenly stopped until the valve has been closed. After use. ensure that the hydrant valve is properly closed and there is no leakage. The valve of the hydrant should not be operated when the pit is full of water unless the stand pipe or hose are first fitted. at least every quarter.
