Best Answer: When the toilet is flushed, the toilet is robbing pressure from the shower, which is usually close to the toilet. As the COLD water pressure goes down from the toilet flush, the HOT water pressure is higher, therefore the water gets hotter as the COLD pressure goes down.
The opposite of a flush toilet is a dry toilet which uses no water for flushing. Flush toilets usually incorporate an S, U, J, or P shaped bend (called a trap, such as P trap or S trap) that causes the water in the toilet bowl to collect and act as a seal against sewer gases (trapping the gases).
