Noisy Drains

Q: We live on the fourth floor in a 20-year old concrete high-rise building. Our manager lives on the first floor. It seems that our kitchen sinks are connected as we can hear them running water, washing up etc. and likewise they get the same from ours. We bought two rubber mats for the sink but find it is of little help. The sinks are not insulated. What can you suggest?

A: I recommend using Poly Urethane foam around the opening in the wall or cabinets where the drain pipe exits under the sink. The product is available in aerosol cans at your local Building Supply store. You might also want to consider enlarging the trap diameter in the kitchen sink to reduce noise caused by running water.
