How do I do start an avalanche effect or clean my pressure tank?

The avalanche effect is a simple procedure which is mainly used to clean the mineral accumulations that have settled at the bottom of the pressure tank. The avalanche effect is also used to clean mineral deposits in the pipe going from the submersible pump to the pressure tank.

If your water contains iron or other minerals that settle over time, it is a good idea to use the avalanche effect, especially before sterilizing the well. The avalanche effect will clean the piping, leaving less interference for sterilization. It is also advisable to do this before taking your water samples for analysis. This way, the accumulation of iron and other minerals at the bottom of your pressure tank will not interfere with the analysis data.

Note :
It is always best to run the avalanche effect with 2 or 3 people depending on the chosen procedure.

There are 3 ways to evacuate the water to a discharge or a drain.

Congratulations, you have just performed an avalanche effect and your pressure tank is now cleaner. Depending on your raw water quality, it is a good idea to perform the avalanche effect at least once every two years, if not more frequently when iron levels are over 3 mg/l. (3.00).


It is wise to perform an avalanche effect if, during the night, a power failure occurs while your water softener is being cleaned (regenerated). In this case, the water pressure drops to zero and when the power comes back on, the pump starts up again and the coloured water observed during the avalanche effect flows into the water treatment system, which can cause coloured water problems and a drop in the performance of the unit. In summary, the avalanche effect is a preventive maintenance that should be performed every two years.


If a home is supplied with mineral-bearing well water that has not been properly treated for several years, these minerals can accumulate in the horizontal pipes of the home. All faucets are equipped with flow restrictors that prevent the proper flow required to prevent the build-up of deposits in the pipes. It is therefore recommended that you do a quick flush of the house pipes periodically. Simply remove the screens at the end of the faucets and, one by one, run water at high flow from each of the faucets to flush the pipes of deposits. Run the water until it comes out clear. Do this for each faucet in the house until all faucets can be run at high flow and the water comes out clear.
