Today, I awoke to water on my bathroom floor. What caused it?
My house has a septic tank and two bathrooms, a master bedroom and guest bathroom.
The guest bathroom had water on the floor, and the bathtub was partially filled with water. The water seemed to be clean. Water was spraying from somewhere under the tank. I shut off the water to the toilet. The tank was very low on water, but it filled more later.
The master bedroom did not have water on the floor, but the bathtub was partially filled with water. I flushed the toilet, and the bowl started filling with water and spilling onto the floor. Again, all water seemed to be clean. I shut off the water to this toilet, too.
Another observation: during the night, I heard occasional sounds, possibly from a flapper, or gurgling, but I did not get up and check the source.
