I live in a condo association of townhouses. Our unit drain lines are pvc, but they all drain into a main cast iron line draining the whole building row.
Most units have high efficiency, condensing boilers or furnaces. Given that the pH of condensate tends to be around 4.5, and the things may run their hardest when little to no activity is occuring to flush and dilute that (late night, early morning), how worried should we be about the effect of running all that acid down the lines?
I'm leaning towards mandating the installation of neutralizers in units, but verifying that the media was replaced when necessary would be a tougher call.
Anyone have some actual experience with this issue? I realize, not that many people still have CI piping, and while ours first is dumped into PVC, it accumulates in a main CI run through the whole building.
