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.
When I was growing up, you couldnt take a shower while the clothes were being washed or the dishwasher was running because the water in the shower would be cold. That is because our water system was not designed to handle both, feeding hot water to each area.f you have the hardware on your fixtures/plumbing to keep the pressure and temperature consistent, then you can do this..if not..I would wait and have a shower when nothing else if running as your pressure and/or temperature can be affected. pissy_old_lady Â· 5 years ago.
