The other night I was running the water in my kitchen sink and noticed a stream of water running down my driveway.  I went outside to find out where it was coming from and I saw that the water was pouring out from under the siding.  I thought could it be coming from the sink?  I went back inside, turned off the faucet and sure enough the water stopped.  I couldn't believe it, there was no water leaking under the sink and I didn't see any water in the basement either.  But, every time I turned on the kitchen faucet water would drain directly outside the house.  Check out the video I took because I didn't think anyone would believe me, aside from my plumber.  Apparently a pipe had busted in the wall and most of the water was draining outside.  Whats your worst plumbing nightmare?
