I went to see my nephew's newly purchased home yesterday. It had been noticed and mentioned to the home inspector about a bubble up in the lower level bathroom.
I myself heard a sound from the kitchen sink drain. At first we thought t was when a toilet is flushed but that wasn't it! I don't know for sure but I "think" it's when the sump pump runs.
Below is a photo taken of the drain header in the basement. After returning home I called and asked for the pictures so I didn't study the system while I was there.
The vertical PVC is coming from the sump pump. I'm wondering what the short vertical piece is for that I have marked, a clean out? There is only one vent pipe through the roof and it isn't one of the large ones form the header but one of the smaller ones.
I was wondering if the drain noise and bubble could be caused if the check valve on the sump pump was bad? If not, what else could cause the problem? If and I'm not positive that it only happens during pump operation, could it be a blockage outside to the main? On the other hand, it doesn't happen when a toilet is flushed! Any ideas?
