We moved into an old house and there is something happening in the basement that I need some help explaining.
Here is a image showing where the leak is happening. I've marked where the water is coming out of with red circle.
The water drips out of there when I flush a toilet multiple times and also turn on water in the kitchen. I believe the water is dripping because the water being drained is too much (just a guess). Because water does not drip when I flush rarely. It certainly has something to do with usage.
The top part of this pipe is shown in this image.
The top part is connected to a water filter (or softner). But here is the image of what it is being connected to
I called a plumber to come take a look and he is convinced that if that 2 inch pipe is made into a 3 inch pipe then that will solve the issue. But I think that might be just a temporary issue....If I use the water too much then it will again drip right?
Also, this problem started happening recently when I changed the toilet. The old toilet used more water and the new one uses less water but sends it down with more pressure. Could that be what triggered the issue?
What would be a long term solution for this?
