In response to Re: Replace old Cast Iron Drain Pipes?
: I am about to replace the old steel supply pipes in my 110 year old house. I�ve noticed a couple heavily corroded/rusted spots on the larger drain lines that I will also need to replace. Since I�m going to have to open a wall or two to do this work, should I consider also replacing the cast iron stack and all associated drain/vent lines with PVC? What is the life expectancy of cast iron? Are there ways to tell its age and/or remaining life expectancy? Is it possible this cast iron pipe (which looks like the stuff I�ve seen in 50 � 70 year old houses) is original to the house? I�ve heard cast iron is quieter then PVC, and really don�t want to tackle this big job unnecessarily, but would hate to skip it and have the cast iron fail in a few years (we plan to be here at least 10 years). : Your thoughts are appreciated! I just completed the same type job and only have one regret. That is I should have left the cast iron venting portions as they are quiet. Now it sounds like a belly flop in the kitchen when the upstairs toilet is flushed, I'm seriously considering putting the Cast iron back in and hubbing in the pvc where necessary
