All:
Recently we started having a couple of events of pinholes leaks on our wet fire sprinkler pipe system.
Since these have affected some high end retail area in our property, obviously people are looking for some solutions/mitigation of future occurrences.
When we checked, the standing water on the pipe was heavy on rust, which is not exactly a surprise as this water might have been sitting on the pipe for a few years.
I thought about adding some corrosion inhibitor into the sprinkler water to try to extend pipe life.
We approached our subcontracted water treatment company, (one of the biggest in the world), that is managing our water chemical treatment on the boilers, cooling towers, etc. for a suggestion and the only thing that they came up with was to use a corrosion inhibitor that would require regular bleeding and water circulation.
In sprinkler system this is not feasible as there are hundreds of branches and not all have bleeding points. It would be madness to even try something like that.
We follow NFPA, so our system is pretty standard and I can't believe that we are the only ones with pinhole leaks in wet fire sprinkler piping network.
So I'm fairly puzzled by the lack of solutions from the water chemical treatment specialist.
Did anybody had same issues with sprinkler pipes?
Thank you all for your input
