Automatic Sprinkler Inspection, Testing & Maintenance

Piping and hangers

Any damaged or leaking sprinkler piping must be repaired or replaced. Loose or damaged pipe hangers and seismic braces must be repaired or replaced. If the exterior of the piping shows unusual pitting or corrosion it may require that the pipe be cleaned and painted. Total replacement of the pipe may be required in cases of severe damage to the piping.
