Fire hydrants are required to be inspected annually, however; manufacturers suggest inspections be carried out twice annually.
The overall colors of a hydrant from city to city can change. Generally, one color will indicate municipal-owned hydrants, and a second color will indicate privately owned hydrants. These colors are often bright colors such as; red, yellow, & green.
A Fire Hydrant's colour on the front cap or top is a way of communicating to the fire department what flow rate to expect from that particular hydrant. Red, Less than 500 GPM, Orange 500-999 GPM, Green 1,000-1,499 GPM, Light Blue 1,500 GPM & above.
Hydrants are flowed for 3 - 5 minutes or until the water runs clear.
Hydrants are required to have a minimum flow rate of 500 GPM (Gallons Per Minute)
Depending on the local municipal hydrant color in the area, private hydrants are usually painted Safety Red or Safety Yellow, using High-Visibility and UV resistant paint.
Permanently Inoperable Hydrants should be removed.
Standard flushing velocities are 0.3 m/sec. Uni-Directional Flushing has an optimal flushing velocity of 1.5 m/sec, this will achieve proper scouring of the pipes.
PVC lines require Uni-Directional Flushing (UDF) to be completed every 4 years. Cast Iron pipes require UDF to be completed annually.
