What’s included
The system is opened and inspected inside for corrosion, debris and obstructions.
Lab testing of system water for microbiologically influenced corrosion and other causes.
Replacing compressed air with nitrogen removes the oxygen that drives corrosion in dry pipe.
Air vents on wet systems and proper drainage on dry systems cut trapped oxygen and standing water.
Standards & intervals
Any of these is a reason to schedule an internal assessment.
| Sign | What it can mean | Next step |
|---|---|---|
| Pinhole leaks | Pipe walls thinning from the inside | Assessment |
| Discolored drain water | Rust or debris moving through the system | Water test |
| Compressor running often | Air leaking from a dry or pre-action system | Inspection |
| Slow or partial flow | A possible obstruction in the piping | Investigation |
Questions
Pinhole leaks, discolored drain water and a compressor that runs constantly are common signs. An internal pipe assessment tells you for sure.
For dry and pre-action systems, nitrogen is widely used to slow corrosion. Whether it fits depends on the system.
