When I run the water in the lavatory for 3 or 4 minutes or longer,I hear gurgling sounds coming from the toilet. It often happens, but not at all times. I was told by a friend that maybe it’s a vent problem. But both vents (the one that comes out of the bathroom and the one that comes out of the kitchen) appear to be clear. I'm wondering why it is doing this.
No announcement yet.
