How to Change a Fire Sprinkler Head
Leave a message
Replacing a fire sprinkler head begins with crucial safety preparations. Always first shut off the main water supply valve to the entire sprinkler system to prevent accidental discharge and flooding. It is also essential to notify any central monitoring service to avoid triggering a false alarm. Once the system is depressurized, use a specialized sprinkler head wrench to carefully unscrew the old head from its fitting, taking care not to apply excessive force that could damage the surrounding pipes.
Prepare the new, compatible sprinkler head by wrapping its threads with Teflon tape to ensure a watertight seal. Hand-tighten the new head into the fitting before using the wrench to give it a final, secure quarter-turn, being careful to avoid over-tightening. Finally, restore the water supply and carefully check the new installation for any leaks. For safety and compliance, this task is best performed by a qualified professional.
