Hello,
I just recently excavated the exterior of my home to install a drainage mat and damproofing membrane. When the hole was excavated, I hired a drain company to scope the weeping tile. During the excavation, I found a clay pipe that attached to the weeping tile that went into the house. As you can see from the photo below, this pipe is slightly lower than the weeping tile. We scoped that clay pipe, but the camera could not get past the elbow, the drain guy said that the section had "shifted". (old post WW2 house,)
The reason for this waterproofing job was to find out the cause of one particular damp area after heavy rain events (as shown in the drawing). It has been determined, that it wasn't the wall that was causing the area after the rain events, but something else (possbibly the shifted clay pipe).
I have also noticed, that when taking a picture of the basement floor drain, I felt a "breeze" where air was entering or exiting the floor drain, but had no odor. The floor drain did have a horizontal pipe facing the exterior foundation wall. I think this horizontal pipe is in addition to the P trap, but I am not sure. I don't know where it leads. Unfortunately the house cleanout (if it exists) is covered by the sub-floor, which i am prepared to tear out if necessary. the distance between the inlet to the house to the floor drain is about 10 feet.
The question is, what is the purpose of a pipe that is attached to the weeping tile system that enters the house? and what direction is the water supposed to flow? (if it flows out, i would consider installing a back water value). Could this pipe be connected to the floor drain (have you heard of such a thing)
Is it connected to the sewer or stormwater system?
I am going to hire a company to deal with this ultimately, but I am asking the questions here becuase i had the impression that the scope guy was as puzzeled as me.
thanks
