Here we highlight only a few main components of a sprinkler riser that play a crucial role in the efficient running of the system. The benefits of these components are only tied to the wet pipe sprinkler system which is a continuous flow of pressurized water into the building through sprinkler heads.
Pressure relief valve and drain valve are some of the important components of sprinkler risers. The pressure in the pipes should be kept constant lest it exceeds the maximum allowable pressure that could lead to water leakages and unplanned explosive discharges. In all our installations we make sure this isn’t the case. The pressure relief valve relieves the excess pressure.
The other main components include the ball valve and a test and drain valve. Pressure gauges are also important and are actually required by the aforementioned standards to ensure a proper pressure of water.
According to 2016 NFPA 13 edition, a commercial or residential riser with a check valve should have pressure gauges installed above and below the alarm check value. This helps measure the pressure rating of the water flow in the riser.
You also have the option between the ball valves and the test and drain valves. The ball valves, for instance, are installed in basic commercial and residential risers to help the sprinkler system to be drained. Testing of this valve should be carried with the inspector’s test and sight glass. Typically, the system should be drained and depressurized through the main drain before carrying out testing.
Then there are the test and drain valves, which is an alternative to ball valves. This valve is covered by NFPA 25 in that it provides the ability to perform hydrostatic testing on the sprinkler system without draining it first. Such ability is attributed to the sight glass included for water observation and the testing orifice that enables the discharge.
All these above-mentioned components are notably important to have on your sprinkler riser. New York Engineers can ensure that you have them installed effortlessly.
Furthermore, there should be a water flow detection alarm, alternatively known as the flow switch alarm, required by NFPA in a wet pipe system. The water flow detector connected to the alarm helps to activate it when it signals water flow. This is a sign that there is a fire emergency since sprinklers are automatic. The actuation of the alarm helps attract the attention of firefighters to attend to the fire.
Although these components are emphasized for the wet pipe system, there isn’t much of the difference compared to other sprinkler systems. Irrespective of the type of sprinkler you need for your premises, New York Engineers can fulfill that for you.
