Having a well at home is sometimes not an option, more than 55,000 people in the Laurentians have an artesian or surface well and a pumping system. There are therefore a few parameters to check to maintain proper operation.

If you do not check your well and pumping system you may have some problems. Discover here the common problems that can cause poor maintenance or lack of maintenance on your well or pumping system.

You will probably be able to fix most common problems yourself.

Here are some steps to take to maintain your system and check your water pump. You can contact us at any time for assistance. Thank you

Common problems and how to identify and fix them easily.

  • Lack of pressure
  • The pump often starts for nothing
  • Air in the piping

How to check your pressure tank and calibrate it

Steps to follow

  1. Connect a garden hose to the bottom of the tank, see photo below.
  2. Close the main valve of your tank
  3. Open the drain valve and run the water.
  4. Watch at what pressure your pump starts, you will hear a click.
  5. When you hear the click, watch the pressure and close the drain valve.
  6. You have just seen the “starting” pressure of the pump.
  7. Keep watching to see the “stop” pressure.
  8. Take note of both pressures
  9. There should be a 20 psi difference between start and stop. ex: 30-50 psi or 40-60 psi
  10. If you have more than 20 psi difference it is better to replace the switch. 2 to 4 psi is tolerable
  11. Tank air pressure should be 2 psi less than starting eg starting at 40 psi your tank pressure should be 38 psi. The air pressure must always be taken without water, to do this follow the next steps.
  12. Close the pump breaker.
  13. Empty the tank until there is no more pressure.
  14. When your tank is empty of water it is a good time to check the integrity of the tank, move the tank from left to right, if you hear water being taken inside the tank your balloon is perforated and you need to replace it.
  15. Take a minimum 50 psi tire gauge.
  16. Check tank pressure.
  17. Calibrate the air with a compressor according to the starting pressure, minus 2 psi
  18. Open the tank drain valve and hold it there. (you will probably need someone to help you)
  19. Go to the circuit breaker and switch it back to the “on” position.
  20. Let the water flow by closing the drain valve and letting the pump fill the tank make 4 start-stop cycles.
  21. Let the pump stop and open your main valve.

Bravo you have calibrated your tank.

How to reset your low level pressure switch.


  1. Start by closing your main valve located at the outlet of the pressure tank.
  2. Then activate the small arm by pushing it upwards (Position 2 on the photo).
    Be careful not to push too high (position 3 on the photo) as this position puts the switch off.
  3. If your pump works, you will see the pressure rise and between 20 and 30 psi the small arm will be relaxed, you have reprimed your pump.
  4. Open the main valve slowly to avoid water hammer.
