Yujie 330 air pump starts frequently.
The reason why Yujie 330 air pump is frequently started is that the check valve of automatic booster pump with check valve return air is not well sealed. According to the relevant public information, the chaotic start-up of the air pump is due to the poor sealing of the one-way valve and the failure of pressure maintenance, and the pressurized water will flow back into the pipeline from the gap of the one-way valve, resulting in the pressure dropping to the lower start-up limit, so the booster pump is started.
