This homeowner is working on an ingenious way to cut down on their water bill. Using a simple white cup as a way to illustrate their very unique water pressure, you won't believe what you see when they turn on the hot water. Who knows, maybe they can even get their bill to go into the negatives? But be warned, you don't want to get contaminated water back in your system! This might look hilarious, but it's always best to call a plumber if you're not sure.
