The toilet did not add water yet. By the way, If you filled a bucket with water, The water level would go up.
Because of the design of the internal trap
The tub and toilet connect to the same drain at some point. The main drain was plugged but the connection between the toilet and tub was still open. Water seeks it's own level. When the water came up in the toilet, the tub was lower so some of it went there.
Each flush of a toilet uses the same amount of water.
It all goes to the same treatment plant and is sent down stream to the next town or city. All tap water is the same, sink or toilet.
Same as a regular toilet.
yes,toilet water is clean it is actually the same water you drink........if its flushed No, it have AIDS in it.
YOU DON'TIt is pre determined by the seal of the trapBasically when the toilet is designed the volume of retained water at the bottom of the toilet is calculated so that it stops effluent gasses coming back up the stench pipe in to the toilet and also to stop waste that goes down sticking to the bottom of the bowl.
Shut the water supply off to the toilet. Flush the toilet. Pull the old flapper out and replace it with the same type. Turn the water back on and test the toilet.
Yes it is .
It depends on the way it is set up, normally the water is from the same source, but using water in the toilet for any purpose other that flushing is NOT recommended..
It will be exaclty the same, the only difference is that flushing the toilet with bottled water is very expense. It really will be a waste of money.
Water is lost from the bodies of animals in the same form as humans. This would be either through perspiration or urination.
