Fire Hydrant Service & Flow Testing
Liquid Logics provides
Liquid Logics offers fire hydrant flow testing for both future development and existing distribution systems performance evaluations. We provide accurate data to engineers and designers for water distribution systems and fire protection systems. Our equipment produces accurate flow data at 20 psi allowing engineers and designers to calculate minimum water main sizes and fire flow demands for various projects.

of the owner:
Esuring that a fire hydrant works properly and is available for use throughout the year is the responsibility of the owner. An alarming number of hydrants are susceptible to freezing in the winter months. Proper maintenance and inspection can help reduce this possibility. Insurance underwriters and municipalities often require annual inspections for proper operation and request flow testing on a three to five year basis.
Annual inspections include:
- Static pressure testing
- Valve operation
- Flushing
- Colour coding & painting
- Barrel Extensions
- Snow markers
- Lubrication
- Repairs
Colour coding helps to identify a private hydrant from a municipal hydrant, and also indicates the rate of flow, giving firefighters important information in the event of a fire.
| Colour | Class | Available Flow @ 20 psi residual |
|---|---|---|
| Blue | AA | 1500 GPM+ |
| Green | A | 1000-1499 GPM |
| Orange | B | 500-999 GPM |
| Red | C | Below 500 GPM |
