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.
  Answer   First off, you do have something heating your hot water! I would start by checking the restrictor/strainer in the showerhead. unscrew the showerhead from â¦ the shower arm and check for debris clogging it. After that I would follow the path back to the water source to see what is causing the problem. Answer   First off, you do have something heating your hot water!
