In addition to doing full Home Inspections and Certified EIFS inspections, I also find myself doing quite a bit of trouble shooting for folks that are having problems in their homes and can't seem to pinpoint the cause.
Today's mission was an intrusive inspection of a leaking shower base. The unit is located on the 16th floor of a high rise building on the upper Eastside of Manhattan.
As you can see, there are no curb walls and there is minimal pitch.
Let's look a bit deeper.
So here we have the heart of the problem.
It's hard to tell from the picture, but besides the fact that the drain is about 2" higher than the sides, the wrong type of drain was used. There are no weep holes to allow the pan to drain and the cone in the middle to compensate for the extreme height simply created a "sink". The pan is always filled with water and is overflowing the sides, running beneath it and into the apartments below.
