After a few failed attempts on our own to reduce noisy drain pipes in our apartment building, I found Soundproofcow online and they put me on the right path, saving us so much time. We tried replacing the DWV pipes with cast iron to no avail. Then foam. No improvement. Then lining with MLV (mass loaded vinyl). No improvement...the noise transferred to the ceiling. So went back online to research and found Soundproofcow. I read "Soundproof 101" on their website...essential reading to understand how sound travels. They also had material specific to drain pipe noise...very helpful. I then called. Even though they knew I wouldn't be purchasing anything (I had already purchased similar materials), they were so generous with their time on the phone. Ryan helped me figure out what we were doing wrong with those materials. He asked me to email him pictures, he replied to my email right away, and then we talked more details over the phone. I wish I'd found them much earlier; it would have saved us so much work. Ryan identified issues that can contribute to the noise (pipes in contact with wood framing, for example), but mainly explained that how you install the materials is everything! Hint: Absolutely NO gaps anywhere in the MLD wrapping of the pipe itself or the lining of the bay in the wall...cover every molecule of surface and tape the seams!
