I shut-off incoming cold water at top of water heater, disconnected the hot side in preparation for new install. Opened house taps to bleed water lines. The next morning my garage was flooded. The water was coming from the hot side into garage.
Now I have confusion for new install, the side that flooded the garage appears to be the incoming cold--the line comes from the left when facing the wall. (I knew the house supply stop valve was not completely closed).
For install would I use the flood pipe for cold???
