Why is the shower faucet cold and hot?

The water pressure is unstable, the hot water is high, and the cold water pressure is high, so it is difficult to adjust. Solution: 1, install thermostatic valve. 2. When hot water is heated, first heat half a box of water, and then fill it with water when taking a bath. At this time, the temperature of the water will drop, so it is easy to adjust when adjusting the water. Try the second method, which is very useful.
