A complete drip irrigation system consists of four parts: water source engineering, head hub, water distribution network and sprinkler (drippers). The drip irrigation pipe (belt) at the end of the system is the most used. According to previous construction experience and case studies, the most common problem in the whole system is the blockage of the dripper. If the drip irrigation belt equipment is not used carefully, it is very likely that the entire drip irrigation system will be scrapped due to serious blockage of the dripper.

1. You can try to increase the pressure to see if the blockage can be flushed out. If not, cut it off and reconnect it;

2. If the pH value is too high, serious calcium salt precipitation will occur. Adding an appropriate amount of acidic solution can dilute it and precipitate it;

3. The undissolved particles of fertilizer in the drip irrigation belt are only temporarily blocked. Don't worry too much about it. It will be fine after a while.
