The peeing pipe!

We had a leak in the basement, so this morning we called a plumber to check it out...
Well, it seems like the workers that put the drywall in our kitchen suck a NAIL in out PIPE...
...and here is a picture to prove it!
Luckily we could break the wall behind the fridge, so we will just put an access panel there and there will be no major damage to the walls...much better than what i expected!
