I live in a row of townhouses. The internal drains are pvc which drains into a cast iron run before it goes out of the building to the city sewer. All of the people have condensing furnaces/boilers. Nobody has neutralization kits on that output. Considering that they will all dribble acidic condenstate into the drain overnight when it is the coldest when nobody is flushing toilets, showering, etc. is it likely that we will have problems with the line? Should we force everyone to install a neutralization kit for the condensate?
