I was looking to use one of the sulfuric acid-based main line cleaners in my very old system. On the warning label it stated that since it dissolves all organic material you need to be careful since organic material may be sealing leaks that you want to stay sealed.
I know I have at least a couple of small cracks in my clay line. Is there really a risk of opening up all kinds of new leaks using one of these products?
