Well at least everyone that has heard it thinks it is funny.
Yesterday I went over to Slaters to walk him through winterizing a RV. I had him hook up a compressor with about 40 PSI to the water supply and open faucets one at a time until they were blowing air. Also had him bypass the hot water heater so he could drain it. I had him by pass the unit then remove the drain valve. Anyone see the step I left out right there?
OK, here are some questions, how fast can a 7 gallon water heater empty with 40 PSI of pressure on it through a 1 inch hole?
Second question how far will said water travel?
First answer: faster than you can see, move or imagine. Say half a second
Second answer - about 4 feet because that is where I was standing when Slater got the drain out.
Yes, I was hit with 7 gallons of water (cold thankfully) center mass. My hat was dripping water and my shoes were wet along with everything in between.
Slater did an incredible job of not falling over laughing or at least not until I had left.
Also, all that stuff in the bottom of a water heater, that all shoots out too.
Lesson learned? Never open a water heater without re-leaving the presser first and where is the video when you really need it?
