Video: Descaling Cast Iron Drainpipes

CONCORD — Larry Williams: Today, I want to talk to you about your drainpipes. Cast iron pipes, as they get older, they will flake on the inside; they will get buildup on the inside. To get rid of that buildup, you have to have your pipes descaled reason being is, as your pipe get bumpier, or that flaking happens, the water will not flow properly. Tissue will not flow properly. It has a tendency to snag and cause a stoppage in your drainpipe.

To alleviate this problem, what you need to do is have your drain pipes descaled. Once the technician comes out and run a camera inside your drain and says you have buildup inside your drainpipes, then you need to have it descaled. He will give you that recommendation. And what it does is, we run chain mail – depends on the pipe chain mail, for cast iron and clay pipes are PVC, but we run a special chain inside of each of those. It will clean the inside of your pipe, and your pipe will flow properly like it was brand new again when you first had it installed in the ground.
