The problem with the pressure in the pump Water jet 60/92 when pumping water
Good afternoon! We have a private house with its own well. We use the pump "Water-jet 60/92 HOUSE" of the firm "Dzhileks", he has a control unit installed on the accumulator.
With it, we can control the pressure of the water supply, but recently, when pumping water, a lot of pressure rises to 7 (normal 3), and after that, the pressure is also relieved instantly and the water injection starts again.
What is the reason? In the submersible pump or control unit?

According to the description of the problem, it looks like the control unit is not working properly. The pump has nothing to do with it, since you have a hydraulic accumulator installed. It seems that due to a malfunction in the electronics, you get a water pressure that is more than double the norm.
With a probability of 90%, it can be argued that there is a breakdown in the control unit, because of which it gives a pressure of 7 atmospheres through the accumulator. And 10% on the fact that in the accumulation tank on the valve there is a mechanical breakdown.
