Ok, so I'm told by the people who installed the boiler in my building (I think it's a wm 80 commercial oil boiler?) three sections rotted and rusted due to excessive replacement water? Weil Mclain (without ever seeing the site, condition-or anything) agreed this was the case.
So-being a non-plumber, I have asked 7 very highly regarded plumbers, and a city inspector if they have ever heard of this....not one has ever heard this in their careers (ranging from 10-35 years). Two plumbers told me there is something on the boiler to regulate the water going into the boiler.
Has anyone ever heard of this happening? Anyone. Thank you for reading!!
