After the water is heated by the water heater, it is now circulated to the vegetable basin, wash basin, and shower, and there is a phenomenon that the water is not hot. Many people are confused and say that there is a problem with the water heater, the water heater maintenance worker said that the pressure of the gas is low, and so on. In fact, everyone has overlooked a problem, that is, there is a problem in the installation process of the water pipe.
In the process of installing the water pipe, it is very beautiful to slot the water pipe in the wall and bury the water pipe in the wall, but some installers do not want to open the wall groove too wide in order to save effort, especially when there are many reinforced concrete walls, the slotting is quite It is difficult, so if you can make less grooves, you can make less grooves, and squeeze the hot and cold water pipes tightly. It is not right for the hot and cold water pipes to be close together. After the test, the two water pipes are close to each other for 20 meters, and the hot and cold water are in a circulating state. The temperature of the water outlet from the water heater is 80 degrees to 70 degrees at the end, and 55 degrees at the end 10 minutes before the start.
When the hot and cold water pipes are separated, its temperature is 80-78 degrees. This test is very telling. Take a water pipe with a diameter of 20 (usually refers to a four-point pipe) and the groove should be (upper end 1CM + hot water pipe 2CM + middle distance 2CM + cold water pipe 2CM + lower end 1CM) a total of 8CM The distance between the two water pipes should be at least not less than 2CM.
