 Fire sprinklers are essential devices for any buildings. They are no longer restricted to industrial facilities, and you can spot them in homes and other residential buildings. They enhance safety in your building by controlling and suppressing fires. However, people proper maintenance ensures optimal functioning of your fire sprinkler, and flow testing is key.

 There are different types of fire sprinkler tests, and the kind of system will determine your choices.

 Types of fire sprinkler tests

The common types of sprinkler tests are; 2” main drain test, water flow alarm device test, fire pump test, and dry pipe valve trip test.

 Main drain test: The main drain test should be performed yearly to ensure adequate water supply at the rinser. Also, it recognizes changes in the water supply that can affect the performance of your sprinkler.

Water flow test: This test is conducted quarterly to ensure optimal functioning of your water flow detecting equipment and alarms. It’s advisable to inform the fire department in your state before performing the test. 

While there are different flow testing solutions, potrasonic flow is favorite among many.  Why choose portasonic flow? This uses a portable flow meter for testing various liquid types. It’s highly accurate with no pressure drops and is time effective with easy installation.

Fire pump flow test: The fire pump flow test measures the performance of the fire pump’s flow pressure. It’s conducted using flowing water with hose steams connected to the test header. The test should be performed annually.

 Dry pipe valve trip test: The dry pipe valve trip test is categorized into two groups. These are the full trip and the partial trip test. The full trip test should be performed after every three years. Can I tell you more? The procedure involves opening the control valve completely to allow maximum water flow. After the test, you should drain the low points and reset the valve.

 Similarly, the partial trip test opens the control valve partially to avoid the release of water. You allow the system to trip in under 60 seconds and drain the low points after the procedure.

 Why is fire sprinkler testing & inspection necessary?

 The degradation of water supply or damages to the sprinkler system can result in severe consequences to your system. Regular testing and inspection is necessary for the proper functioning of your device. Again, you risk fines and citation if you fail to properly inspect, test, and maintain your system.

The functioning of your fire sprinkler system is dependent on the water supply. If there’s inadequate flow or the system pressure is compromised, the sprinkle won’t operate as required. This will allow fires to spread, hence the need for regular checks and tests. Maintaining accurate flow and pressure is critical in the installation process. And this should be maintained through regular testing to ensure optimal protection for your building.

Wrapping up

Fire sprinkler testing is critical for the optimal functioning of your system. Otherwise, it won’t be effective during fire breakouts and can lead to unimaginable losses. Also, corrosion may cause blockages and which exposes your building to multiple risks.
