Piping Life Expectancy
I live in Houston, Texas, and am considering buying a condominium. Everything looks great, but I am concerned about the piping. The condominium complex was built in 1981. None of the piping inside the walls has leaked as of today. Also the adjacent 7 units have had no leaks. My questions are: 1) What piping material was used in those days for home internal piping systems? 2) What is the life expectancy of the different types of piping (copper, steel, etc.)in a home?
It's probably copper pipe. Look under the kitchen sink to see what kind of supply lines they used. The life of the pipe itself is unknown. I would say, 50+ years. The solder joints are what you should be concerned about. You don't want to see a telltale green residue. This is a result of the plumber not wiping off the flux (acid) after soldering. Can also be a result of electrolysis. (2 dissimilar metals reacting to each other) I have seen it countless times in new construction. These guys get paid by how many houses they can do in a certain time frame. Sounds like you should be ok. Good luck with your purchase.
