Inspection

At Hydra-Spec, we will diagnose your water system by inspecting your fire hydrants and main line valves. Trust our fire hydrant inspection service today.

Goal

Fire hydrant inspection

Our mandate is to carry out a systematic fire hydrant inspection in order to determine the capacity of the network, the sectors with the possibility of leaks and the operating condition of this equipment, as well as the preparation of a computerized report.

Fire Hydrants

A computerized and detailed report of the results of the inspection and analysis of the fire hydrants as well as their isolation valves is given to the customer in electronic format.

Types of Inspection

Complete inspection carried out only once a year.

Inspection carried out twice a year (spring, fall).

Spring, fall and winter inspection.

Hydrants Inspection

General Method

The technician will complete an individual inspection sheet for each of the fire hydrants including this information

First criteria

the number of the plan and the fire hydrant
the location of the fire hydrant as well as the sector (e.g. industrial)
the make and model of the fire hydrant
accessibility to the fire hydrant
accessibility to the fire hydrant isolation valve nut
description and operating condition of the isolation valve
the number of hose outlets and their diameter
condition of hose outlets and plugs
the thread pitch of the hose sockets
the height of the flanges from the ground level
the aesthetic condition of the fire hydrant
the height of the water table above ground level
the depth of the fire hydrant, i.e. the distance between the boot and the flanges

Second criteria

description of the operating condition for all the different mechanisms
drainage quality
the tightness of the body and the caps when the fire hydrant is open
the measurement of static and dynamic pressure in order to calculate the actual flow rate and the flow rate when the dynamic pressure is at 20 psi (138KPa), taking into account the type of elbow installed (ex.: 45o and 90o), taking into account the coefficient out of the outlet
recording using an acoustic amplifier of the noises coming from a leak
water aesthetics (rusty water, deposits, gravel)
the date and time of the inspection and the name of the inspector
the visibility of the isolation valve, its position in relation to the fire hydrant as well as the physical condition of the valve box (once a year).

Description of any interior or exterior damage

faulty operating sleeve
split crankcase
leaky lid
bent rod

Winter Method

It is a mechanical and visual inspection of fire hydrants

Sealing

sealing of the network with geophone
sealing of the main valve (opercule)

Verification

checking the water table
checking the upper mechanism
verification of interior components such as rod, crankcase and coupler
verification of the structure and the external condition

During The Inspection

The technician performs the following operations:

Once a year

when the fire hydrant isolation valve is accessible, the technician manipulates it to ensure that it is open and operational

Lubrication

lubrication of hose outlets and plugs

Annual or fall inspection

emptying fire hydrants that do not drain to prevent freezing

Rinsing

flushing the fire hydrant and the section of pipe between the fire hydrant and the water main
