I have a 2003 Rheem Natural Gas Water heater. The weather here has gotten extremely cold and my mother and I installed some foam pipe insulation on the cold water supply line into the water heater. She had some trouble getting some of the insulation to stay and was bumping the ball valve which controls the water flow to the water heater.
Immediately after we finished this, I checked the hot water pressure on all the faucets and it was a trickle. After opening all the hot water faucets in the house, it took less than 45 seconds for full pressure to be restored. I went outside and turned the ball valve on and off several times. Then I checked the hot water pressure again and all seems to be fine. I have checked underneath the house and it is dry no leaks so far as I can tell.
It has been a few hours since this happened, but the water pressure seems to be o.k.
Should I stay alert to this situation or could we have knocked the ball valve partially closed and it took a few minutes for the pressure regulate itself.
Any advice or ideas would be greatly appreciated.
