The inspectors test on a sprinkler system only flows the same water as
a single sprinkler. It is used to test the Alarm Check Valve, water
motor gong, and the water flow switches that activate the buildings
alarm system. It is not an effective way to flush the system. Many
residential sprinkler systems do not use black iron piping and do not
contaminate the water used in them. Copper tubing and plastic piping
are both used in residential sprinkler systems because the piping
installed in such occupancies is not as subject to physical damage as
the piping that is installed in warehouses, factories, and other
industrial buildings.
