Any mechanical equipment must be regularly cleaned and managed before and after use, in order to prevent its equipment from being damaged in a short period of time, and the same is true for drip irrigation pipes. Especially in winter, under the influence of the environment, it is necessary to put away the equipment and not use it for a long period of time, and then use it again in the spring of next year, so we must clean the equipment before putting it away. The following are the key points of cleaning.

1. Drainage bottom valve: Open the drainage bottom valve located on the main and branch pipelines in the field, and drain the water in the pipeline as much as possible. This valve does not need to be closed in winter.

2. Field valve: put the manual switch of each valve in the open position.

3. Drip irrigation pipeline: Straighten each drip irrigation pipeline in the field, do not twist it. If it is recycled in winter, be careful not to twist it.

4. All ball valves should be removed and dried and placed in the warehouse or placed in a half-open position to prevent the valves from being frozen and cracked.

The above are the key points for cleaning drip irrigation pipes in winter, and there are other precautions that will not be explained one by one. To sum up the above, if the equipment is not cleaned before it is put away and not used, problems may occur when the equipment is used again.
