Plumbing Mastery Challenge: Can You Diagnose, Fix, and Prevent Common Issues?
1. If the water in the water heater is too hot on the left side (hot water side) and too cold on the right side (cold water side), what may be the cause?
Correct Incorrect Faulty thermostatic valve (or mixing valve) will cause abnormal mixing of hot and cold water, causing one side to be too hot and the other side to be too cold. First try to clean or adjust the thermostatic mixing valve, and replace it if it does not work; at the same time, check whether the pressure of hot and cold water is balanced, and contact professional repair if necessary.
