After receiving questions about the sound of plumbing systems, Charlotte Pipe performed an experiment testing cast-iron soil pipe, solid-wall PVC and foam-core PVC with and without insulation products. Viewers can see the experiment at www.charlottepipe.com/dwvsoundtest. The video is segmented by product so viewers can choose to watch all products or jump to specific material. Charlotte Pipe stresses this test is an experiment and not an endorsement of a pipe material or insulation.
