What is a micro switch tap?

In the micro switch system, each tap contains a micro switch. Turn on the faucet and the pump will run, and turn off the faucet and the pump will stop. There is a micro switch under each faucet, which can be hot or cold, so there may be six, so there are more places to go wrong.

You can confirm whether it is a micro switch by tapping the switch once. Micro switches are used in vintage trucks before 1995.

If the faucet fails to operate, the pump will slightly open another faucet. This should turn on the pump and water will flow from the first tap, most likely indicating a micro switch or wiring failure. The micro switch is located at the bottom of the faucet. You will need to remove the faucet and it is best to replace the entire faucet.

The pressure switch system is simpler than the micro switch system because it has only one pressure switch to switch the pump. The faucet only needs to open or close the water flow or flow up or down. When the faucet is turned on, the pressure switch only detects that the pressure in the pipe has dropped and runs the pump. Turn off the faucet, the pressure switch detects the pressure rise and stops the pump. If there is a slight leak in the pipeline, even if the faucet is not turned on, the pump will occasionally run to maintain pressure.

If there is a surge damper, the pressure switch works best and can pump smoothly. You can adjust the flow of the faucet from very slow to fast. You need to adjust the pressure switch correctly. To do this, turn on the cold water tap and turn it off slowly until the water drips slowly. Then adjust the pressure switch until you hear the sound of constantly opening and closing.
