I recently had a conversation with a property manager about installing water meters on steam boilers with automatic water feeders in order to detect if the automatic water feeder is adding too much feed water (like if there is ever a leak in an underground wet return or a hole in the boiler, etc)
He insisted that installing the meter doesn't need to be done because he has a chemical company that monitors the PH level of the boiler and they would know if there were an issue. He said that they come out once a month to test the boiler water.
I don't know how a company measuring the PH level would know if there was too much feed water being added because I assume in some areas the feed water is the same or similar PH as the water in the boiler (we are in Boston). Maybe the company adds a chemical or something and monitors the presence of that chemical. I have no idea though.
Does anybody have any insight about this? Is the property manager wrong? I thought I read from one of Dan Holohan's articles that the only way to tell if you are taking on too much feed water is to meter it: http://www.heatinghelp.com/article/323/Boilers/244/Steam-Boiler-Failure (see 3rd paragraph from bottom). Does that hold true in this case?
