What is in the device?

The hardness remains the same; it may even rise a bit temporarily when lime deposits are released from the pipes. In almost all cases the AquaKat brings about a stabilisation of the hardness, but no softening. However, the water feels a lot softer after installation of the AquaKat.

Hardness stabilisation is a physical process by which the crystallisation behaviour of the water components changes in such a way that the crystals do not form chains or clumps. Also they do not form aggressive lime scale anymore.

You can compare the initial condition with the condition after installing the AquaKat. Here an example:

Which subjective changes did you experience with ...?

Removal of lime, water colour (clearer), water taste, food (taste), detergent (savings), laundry (softer), easier to clean, skin and hair (feel, look, maintenance), plants (appearance, health), animals (appearance, well-being), etc.

In a pressure cooker there are temperatures above 100°C and enormous pressure. Under these conditions, the lime scale starts forming again.

over time. So this „old“ water with its lime forms a small deposit that builds up over time.

Therefore empty the kettle fully after boiling and rinse if necessary

If the effect varies, it is mostly due to these factors: Change in water quality, connection and disconnection of electrical equipment in the area where the AquaKat is mounted (sources of interference), habituation to the effect, formation of deposits between the mounting clamp and the pipe (must be removed).

If the fluctuations happen continuously, contact the seller.

Then several factors need to be checked into: Where and how is the AquaKat fitted? What were the expectations? Are there sources of interference and / or other devices nearby? The water quality, water quantity and the pipe material have an impact on the effectiveness. It is recommended to uninstall the AquaKat, to clarify the issues and to install it again a week later; it might also be necessary to fit a second AquaKat.

Again, several factors need to be clarified: Have new (electrical) devices have been put into operation? Is the water supply different (ask waterworks, new appliances, different mix, etc.)? Is the AquaKat properly mounted or perhaps fallen down? Have deposits formed between clamp and pipe? Have large amounts of water been used? Have you already gotten used to the good quality? Is the lime structure the same again? When in doubt, it is also advisable here to dismount the AquaKat and fit it again after two weeks. Also a vinegar test is recommended! A replacement of the AquaKat can only then be taken up for consideration (see also questions 34 and 35.

This is a very positive effect! Lime and other material such as iron (rust) are released from the pipes. During this time, the pipes should be frequently and thoroughly flushed.

Unscrew and remove the deposits.

That depends solely on the quality of the water supplied. Many substances are not recognised in a simple analysis (15 parameters).
