After some people installed a booster pump, the water pressure increased, but they found that the booster pump often beeped and stopped (that is, started and stopped) when no water was used. What is going on?

In fact, this is a common problem of many cheap automatic booster pumps. The main reasons for this phenomenon may be as follows:

1. The check valve is leaking. The check valve itself can only go in but not out. If a check valve with poor quality is used, when the water pressure in the pump chamber increases, the pressurized water will seep back into the water inlet end of the pump, causing The pressure inside the pump chamber decreases. After the sensor detects the decrease in water pressure, it will restart the booster pump to compensate for the pressure. Since there is no water in the water outlet direction of the pump, the pressure is quickly replenished, and the booster pump immediately goes into sleep mode again. The reciprocating cycle causes this phenomenon of beeping and stopping. The solution is to replace the one-way check valve with a quality-approved one. In fact, most of the causes of beeping and stopping are caused by the check valve.

2. There is a leak in the pump outlet pipe. The principle of water leakage in the direction of the outlet pipe causing a beep and stop is the same as the leakage of the check valve. The reason is that the water pressure in the pump chamber is reduced and the water pump is restarted to compensate for the pressure. Since the water output in the outlet direction is very small , causing the pressure to rise to the set pressure value in a short period of time and causing the booster pump to shut down to maintain pressure. After the pressure is reached, the water pressure will drop due to water leakage, and the booster pump will replenish the pressure. The reciprocating cycle will cause a beeping and stopping phenomenon.

3. Sensor failure. This phenomenon will also occur when the pressure feedback is inaccurate. The principle is actually the same. When an incorrect low pressure is fed back, the booster pump will also compensate for the pressure and cycle back and forth.

4. The frequency of water use is too high. If the booster pump is controlled by pressure difference, it will also cause the phenomenon of starting and stopping when water is used frequently. The reason is the same as water leakage in the outlet pipe, and this situation may occur more frequently when it stops, especially if there is no pressure tank to stabilize the pressure. If you want to completely eliminate this situation, it is recommended to change the differential pressure controller to a frequency converter control, or directly replace it with a new variable frequency booster pump to solve the problem of beeping and stopping when using water.
