said by robbin:Our previous house that we rented (built in 1949) had horrible plumbing. The toilet was always backing up. The town was notorious for orangeburg as you were always seeing yards being dug up because of orangeburg. I suspect our old house had orangeburg.
One of my rent houses was built in 55. We just pulled a permit to replace the orangeburg. It has severely deformed to the point that the 4" pipe is less than 2" tall in some places. Have another house of same age and have leak in cast iron from rust through.
