Sump Pump Exit PVC through Basement Wall
In our Wisconsin home, we have a sump pump that has a pipe that runs through our basement wall out of our house that allows the sump pump to send the water to our local municipality. Last night I walked down during a heavy snowy/rain fall and I saw a small amount of water coming in through the hole where the pipe runs through. It wasn't a great amount of water but it was still water coming into the house.When the sump pump ran, it didn't appear that it was leaking out of the PVC pipe just as an FYI. It almost appears that it is coming in from the outside below ground, and working its way back into the house from the exit point of the tubing.
My question is do I caulk the entire hole, do I put great stuff insulation into the hole, do I put some sort of styrophone in the hole to stop the water from coming into the house, but what happens if there is water sitting in the hole, will that mold, cause issues with the foundation.
