What Is This Capped Pipe?

[JohnP]

A couple of days ago we had very heavy rains and the entire first floor of our condo (located above a parking garage) flooded. The water was coming from within the wall that separates the living room from the outside patio. After opening up the drywall we found a 2-3” diameter (at the time uncapped pipe) sticking up from the floor about 6 inches (see photo showing the pipe after it was subsequently capped). This is where the water came from.

The assumption is that the builder forgot to cap this pipe during construction.

Can anyone tell me what purpose this pipe serves? Would be much appreciated.

'prolly a deck drain or roof drain that got forgotten



just for your knowledge
that rubber cap is for testing, it is not a permanent cap
if you bury it in the wall, over time the rubber will get brittle and you will have the same problem all over.
get a cast iron cap and a no hub band

Who roughs in a drain and doesnt hook it up. How did it pass inspection and why did the drywall guy not say hey whats up with the open pipe. What the hell goes on in this world.

Thank you all for your feedback. Plumber decided to run a camera down the pipe withing the next day or two - so hopefully I'll have more clarity then.
