Hi,
I have a house that’s about 10 years old, but have only been here for 8 months. A few weeks ago when using the master bath shower a very loud groaning/vibrating noise began. It also occurs when using the cold water in the sink. It lasts anywhere from a few seconds to 30+ seconds. I followed the noise over to the toilet area, but don’t know what to do. Any advise would be appreciated.
Thanks
Diane
