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.
Toilet bowls sweat because the air around the toilet is considerably warmer than the temperature of the toilet water. This creates condensation and causes the toilet to sweat. You can purchase an anti-sweat toilet kit to insulate the tank and reduce condensation. The kits are inexpensive, easy to install, and are very effective. Liners are applied with an adhesive to the inside of the tank. They are nearly permanent, and will require some effort to remove.
