How to find out a middle basement leak?
Just last September, for an investigation project CCPC was hired to find a basement leak located in the middle of the basement during a heavy rain storm.
After I arrived the house and sitting down wit ht he tenant to tell me the story of the leak. He was saying that it has leaked a few times recently that is why the drywall and carpet around the stairwell were still wet.
We went down and took a look. I approached the leak with skepticism. Normally, moisture seepage is coming through the exterior walls, how it ended up in the middle of the room? What is going on?
I applied the thermal imager and confirmed the carpet and drywalls around the stairwell were wet.
Next, I went outside to check for any exterior cracks on the foundation walls and there were no major, usual cracks that might cause seepage into the basement.
Then, I went back to the basement. After spending some time down there, I heard water dripping noise somewhere and I searched for it. What I found was a laundry hose inserted into the floor drain and was still dripping inside the cold room.
Again, I applied my thermal imager to the dripping water and found the temperature to be quite warm. I used my hand to test and confirmed it was warm water.
What happen was that someone did not turn off the hot water tap completely leaving the water drip and subsequently it overflow the drain and back up. That is why the middle of the basement has moisture.
This is another good application for using a thermal imager!
