It Is Worth Replacing Your Clay Or Terra Cotta Sewer Pipes?
If you are experiencing water leakage through your home’s clay or terra cotta sewer pipes, it is highly recommended that you replace them with the modern PVC variety.
Unlike PVC and other forms of plastic, clay sewer pipes aren’t able to fit flush together. No matter how well they were laid, there will always be little gaps between the sections of piping.
Clay flaking occurs on the inside of a clay pipe. Slowly but surely, a few flakes will turn into a few more flakes, and before you know it, your clay sewer pipes will be compromised.
Whether clay sewer pipes were ever-so-slightly misaligned from the offset or from ground movement matters little, what does matter is that they are misaligned.
