CPVC pipes are typically beige in colour, while PVC pipes are white. It’s important to ensure proper installation of plumbing lines, including adequate mounting and support. Sagging or bending CPVC pipes may not meet plumbing standards. I recommend consulting a qualified plumbing service to assess the installation and provide appropriate guidance. Properly installed plumbing is crucial to avoid issues like leaks and water damage. Feel free to contact us for further assistance.
