Why does my shower get hot when I flush the toilet?
So, when you flush the toilet, it needs water to fill up the tank. The toilet gets the water from the trunk pipe and, if you’re showering during this time the shower will have less cold water coming from the trunk pipe. Therefore, the shower’s temperature will heat up!
What to do if your shower gets hot when you flush the toilet?
If you’re up for a bigger project, you can install a pressure-balanced valve on your shower. This will compensate for a sudden drop in water pressure caused by a flushing toilet, by reducing pressure in the hot water line to match the reduction in pressure in the cold water line.
Why does the shower get hot or cold when you flush?
Thermostatic mixing valves automatically balance the amount of hot and cold water being mixed, which will prevent drastic fluctuations in shower temperature. If the cold water flow is reduced (due to a toilet flush), the valve automatically adjusts the amount of hot water being mixed.
What happens to the water when you flush the toilet?
Your 12 year old daughter flushed the toilet downstairs! The shower temperature was perfect. A shot of scalding hot water comes out of your shower head and your skin is burned. Now your temper is as hot as the boiling water. The changing water temperatures can be dangerous on your skin—and to your pocket book. Cold and hot.
What can I do to keep my shower hot and cold?
A mixing valve monitors the water pressure of the hot and cold water coming into the shower. So if the cold water pressure drops (like when a toilet is flushed) it will also drop the hot water pressure. This helps keep your shower at a constant temperature. Fix your plumbing system. Install a more sophisticated load balancing manifold

Why does my shower water pressure drop when the toilet flush?
Basically, they work by adjusting the ratio of hot to cold water pressure. So when your toilet flushes it pulls cold water from your shower. The pressure-balancing valve senses the drop in cold water pressure and responds by restricting the hot water pressure.
This means less supply to the mixing valve in the same setting. Modern thermostatic mixing valves are designed to keep the total pressure constant. This means that a reduction in cold water pressure (from a flush) is detected and the mixing valve responds by reducing corresponding flow in the hot water.
