What is the reason for the frequent jumping of the self-priming pump?

The reasons for the frequent jumping of the self-priming pump are: 1. The delivery distance is long, the height is high, the required pressure is large, and the pressure set on the pressure controller cannot meet the usage requirements. You can first open the controller cover and then use a flat-head screwdriver to turn the central adjustment knob clockwise upwards to obtain higher pressure; 2. There is no gas in the pressure tank on the self-priming pump. You can unscrew the inflation nut on the pressure tank and use an air pump to add gas inside so that the pressure tank can play a stabilizing role; 3. When the user installs the self-priming pump, the inlet and outlet are not equipped with a check valve, causing the water to quickly return after the pump stops. After the outlet pressure drops and falls below the preset pressure, the fully automatic self-priming pump will start again. The solution is to install a check valve at the outlet of the self-priming pump; 4. If the faucet is not closed properly or there is water leakage elsewhere, causing the outlet pressure to drop, the self-priming pump will also start automatically. Check the faucet's closing status and find where there is leakage to solve the problem; 5. If a fully automatic self-priming pump that has been used for a while was previously in good condition but suddenly starts and stops frequently, it may be due to a faulty automatic switch. You can replace the automatic switch to see if the fault persists.
