I woke up to the sound of water running. I hate that.
It seems that a valve under the dining room seat burst and was spraying water. I am not sure how long it was spraying before I woke up, but there was a lot of water on the floor. I opened the door of the motor home to retrieve a mop from my "basement storage" and the ground outside was wet with little puddles all around the motor home. Water was dripping from several places under the motor home.
I shut the water supply off.
