Preventative Maintenance for Sprinkler Systems.
by Wade Weatherbee
The following is a brief outline of my presentation to the members of the Building Operators Association on January 14/97.
"Be prepared for the Calgary winters and avoid costly repairs."
- Check freezing levels of the Propylene Glycol solution in anti-freeze systems.
- Drain and blow out all dry system low points and ensure proper grade.
- Test warning devices for proper activation, i.e. low air and temperature sensors.
- Maintain bearings, packing and circulating valves on fire pumps.
"Don't cry Wolf, prevent false alarms".
- Test and adjust flow switch delay settings.
- Replace alarm valves with flow switches during backflow installations.
- Convert excess pressure pumps to automatic, vs manual.
"Avoid embarrassing situations"
- Ensure your fire pumps start and perform as required.
- Check that all isolation valves are in proper positions, "usually open".
- Test hose valves and fire department connections for proper threads.
"Protect our environment replace Halogenated fire systems"
- Check out the new alternatives for Halon, such as "double-interlocked dry systems" and "Inergen" systems.
For more information on any of the above topics, please contact Wade at Grinnell Fire Protection, 403-651-7334 or by fax 403-243-6966.
