I live in the bottom floor of a 5 story house, and we just got a new main sewer drain pipe (a vertical pipe for bringing waste water out of the house). That s very nice but somebody on the upper floors uses water, then I get a lot of noise in my appartment. The pipe is vertical, but it has a kink in my appartment, and I think this kink is the reason for the noise. Sometimes the water falls down several stories before hitting the kink.
I mailed the consulting engineer about it and he said that it is normal for new drain pipes to be noisy, because they are clean on the inside. Is that true? Is there anything the plumbers could have done to reduce the noise?
I write here, because I don't know whether I should be pationt or complain about the work. If I want complain it is a good time to do it now, because the plumbers have not been paid yet,
Thanks in advance
