Installation of hot and cold water pipes: Many people will encounter the situation that the water temperature fluctuates from cold to hot during the process of water use. Apart from the problems of the electrical appliances themselves, it is actually very likely that the distance between the hot and cold water pipes is too close during the laying of the hot and cold water pipes. Another point to note is that the hot and cold water pipes should be distinguished. PP-R cold water pipes have relatively low pressure bearing capacity at high temperature (recommended below 40°C), and should not be used as hot water pipes, otherwise there may be a risk of pipe bursting. If the PP-R hot water pipe is used for a long time, the maximum temperature cannot exceed 70 °C, otherwise it will also affect the service life of the PP-R hot water pipe, so this point should also be considered when setting the hot water temperature. (The distinction between hot and cold water pipes: there is a red line mark on the hot water pipe, and a blue line mark on the cold water pipe, and there are text marks.)
Suggestions for installation before and after waterway construction: Be careful when selecting materials. The quality of household water pipes directly affects the health of household drinking water and property safety. A little carelessness can become a big trouble. System testing is indispensable, and acceptance is the gate of decoration. It is necessary to test the pressure-bearing performance of water pipes and welding process, so as to minimize the hidden dangers of waterways and cannot be ignored. Therefore, after the construction is over, no matter how busy or no time is available, be sure to invite a professional team and a plumber to personally participate in the inspection and acceptance at the site. It is necessary to record the drawings. After completing the piping diagram of the waterway, remember to record the drawings for later maintenance.
