Making a strong argument for an entertainment stand instead, this is a short video of the aftermath of a man hitting a waste water line while installing a flatscreen television mount. What’s he doing, trying to will the water back into the pipe with a towel? Is that water blue? Is that from a toilet with a 2000 Flushes toilet puck in it? If that’s the case, you should be able to cut the toilet’s water from behind the commode pretty quickly. Otherwise you’re going to need to locate the water main. Alternatively, just start charging admission to your water park.
