What are the signs of a faulty pressure switch?

The pressure switch plays a crucial role in maintaining the correct pressure in your well pump system. This device acts as a pressure switch, controlling the operation of the submersible or surface pump coupled to a pressure vessel.

Here are 4 signs that could indicate a faulty pressure switch:

• Low water pressure: If you find that the water coming out of your taps is under-pressurized, this could indicate a problem with your pressure switch. Your pump may not be able to maintain adequate pressure in the system.
• Water pressure fluctuations: Inconsistent water pressure fluctuations can also be a sign of a faulty pressure switch. If your pump switches on and off irregularly, this may cause changes in water pressure.
• Unusual noises: If you hear strange noises coming from your pump, such as rattling or grinding.

What is a pressure switch?

The pressure switch functions as a pressure switch. Its main function is to activate or deactivate the pump’s electrical circuit. When the water pressure rises to a preset level, your pressure switch takes the initiative to switch off the pump. This prevents excessive pressure which could damage your well pump system.

On the other hand, if the water pressure drops below a certain level, your pressure switch reacts by switching on the pump. This ensures a constant supply of water at the right pressure.

How to check that your pressure switch is working properly

Continuity test (using a multimeter) :

1. Switch off your system’s power supply.
2. Disconnect the wires connected to the pressure switch by removing the terminal connectors.
3. Set your multimeter to continuity mode.
4. Touch each multimeter probe to one of the pressure switch terminals.
5. The multimeter should display a value close to 0 ohm (indicating no resistance).

Voltage test (using a multimeter) :

1. Make sure the power is off.
2. Reconnect the wires to the pressure switch.
3. Set the multimeter to measure AC voltage (V AC).
4. Touch the multimeter probes to the pressure switch terminals.
5. The multimeter should display a voltage corresponding to your system configuration.

Use of a pressure gauge (for more accurate measurement) :

1. Connect a pressure gauge to the pressure switch.
2. Increase pressure until the pressure switch changes state (opens or closes).
3. Note the pressure value at this point.

Keeping your well pump system in good working order is essential to ensuring a constant, reliable water supply. As a well pump service provider, we can help you if you encounter any of these problems.
