To avoid leaks in heating pipes, it is recommended to take the following precautions:
| measures | Execution method | cycle |
|---|---|---|
| Regular inspection | Check the status of pipe connections and valves before heating | 1 time per year |
| stress test | Observe whether the pressure gauge is abnormal when filling water | Initial stage of heating |
| Anti-rust treatment | Apply anti-rust paint to exposed pipes | every 3 years |
