We have a fairly new house that we bought in november 2017. We had heavy rain 2 weeks ago and since then, we have noticed unpleasant smells in multiple sinks when running water. It seems like it is coming out of the overflows of sinks. We can also get the smell from the bathroom sink when draining a full bath.
I suspect the vent system to be the issue but there are no gurgling noises coming for any toilet or sink. It is as if when running water, some sewer gas was able to make it's way in the overflow of the sink for the duration of the use. Could that be due to a high pressure in the vent stack? If so, could it be from the council drain pipe pressure?
