1. When pressing the floor heating, clean the heating pipe, and then check whether the laying is fixed. Generally, the pressing of the floor heating is 1.5 times the working pressure of the system.
2. The water injection speed of the floor heating pressure should be slow, and attention should be paid to the gas discharge of the heating pipe. After the floor heating system is full of water, the tightness of each interface can be checked.
3. When the local heating pressure reaches the working pressure, it can be stabilized for 5 seconds, and then check whether there is water leakage at each interface. After checking that there is no problem, observe the pressure gauge. Generally, within 10 minutes, the pressure reduction of the pressure gauge is less than or equal to 0.03MPa is qualified.
4. When pressing the floor heating in winter, pay attention to the antifreeze protection of the pipeline.
