Oil leakage in the pipeline of range hood is a common problem in families. Oil leakage will pollute kitchen walls and ceilings, and it will also bring hidden dangers to people's health. To avoid this situation, the following measures can be taken to repair the oil leakage problem:

1. Cleaning the pipeline: First, you need to turn off the gas, power supply and range hood. Then, remove the pipe and clean it. In the process of inspection, if the pipeline is found to be damaged or aging, it can be repaired with glue.

2. Replace the new pipeline: If the oil leakage location is not obvious or the pipeline is damaged, it is recommended to replace the new smoke pipe. You can buy new smoke pipes that meet the specifications from the professional building materials market and replace them in strict accordance with the instructions.

3. Install the leak-proof pad: When disassembling the range hood, you can find that sometimes there is a gasket at the nozzle, which is the leak-proof pad, which can effectively prevent oil leakage. Gaskets can be replaced or leakage-proof gaskets can be added at the nozzle.

4. Rationalization of exhaust pipe installation: When installing the exhaust pipe of the range hood, attention should be paid to the natural ventilation of the upper and lower pipes to ensure their smoothness and avoid the hidden dangers caused by the accumulation of grease and foreign bodies.

In short, to ensure that the pipeline of the range hood does not leak oil, it needs to be inspected, cleaned and oiled regularly, and it is not a big problem to keep the pipeline dry and unobstructed during use. If there are problems such as oil leakage, deal with them in time and take measures to repair them, thus effectively preventing the adverse consequences caused by oil leakage.
