I roughed in the plumbing for a house last year. Alll new waste, vent and water pipe. All waterlines were capped off at fixtures. I filled the electric water heater with water and turned on the electric to make sure it was heating. I mistakingly left the electric on to heater but turned the water off at the main. 6 months go by I come out to start setting fixtures. I check the main valve...still off. The first copper cap on the hot side is too close to the cabinet to cut so I go to sweat it off. There I am under the kitchen sink with a torch when the cap blew off and stuck me square in chest like a bullet. Make that a red hot bullet. Ok yea the pressure blew it off, I get that, what I don't get is why a 4' flame came shooting out of the pipe. That scared me more than the cap plunking me in the chest.
No announcement yet.
Has this happened to you?
