I was taking a long, cool, somewhat refreshing shower the other night... longer than usual, when suddenly hot water came spewing out of the shower nozzle! Ahh, hot water! I did not know I had hot water, since my other showers must have been shorter. The next evening late, I turned on the water to let it heat up... 5 minutes, 6 minutes, 7 minutes, hot! I then proceeded to wash my hair and just relax. Suddenly, habis, finished... no water! I fiddled with the nob to no avail, then rinsed with cold water and went to bed. In the morning, as the roosters crowed, I heard water splashing in the shower! I had not turned the hot knob off. The hot water must get completely turned off at night.
