Just bought a townhouse three mounts ago. When running water in the sink - tub or shower from the sound floor full bathroom. There is a clicking or dripping sound coming from the drain pipes in the wall. Unable to find any water stains downstairs ceiling or wall. Called plumber they state the pipe is expending then creating a clicking noise. Called another plumber for second opinion. Same answer Would like to find a cure regarding the noise as I just painted the whole townhouse as well installed laminated flooring on the first floor
I'm very concerned that this could be a link that can cause bigger problems if prolonging the issue.
