The resin cartridges in your Basic 40 softening system generally do not need to be replaced because they regenerate themselves. The regeneration of the resin is an automated process that takes place during the cleaning cycles of the system. Here are some details:

In summary, the resin cartridges in your Basic 40 system are maintained effectively by the built-in regeneration process and therefore do not require regular replacement.

It is best to let the salt empty until the water is visible.
Then refill and ideally not full to the brim so that there is not too much weight on the salt.

If you keep filling the container without waiting until you see the water at the bottom, clumps can occur.

According to the DIN standard, maintenance should be carried out by a specialist at least every 12 months to ensure optimal function and safety of the system.

However, our water softening systems are designed to be so reliable that many customers carry out regular checks themselves. As long as the system is working properly and no problems occur, there are no legal requirements that make maintenance mandatory. Nevertheless, we recommend checking the system regularly and calling in a specialist if necessary to ensure long-term safety and efficiency.

Regarding the ALFILTRA FCA 30 deacidification system and the calcite refill requirement: Over the course of use, the amount of calcite, which serves as the main medium for water deacidification, will gradually decrease. This is a normal process caused by the continuous neutralization of the acid in the water. Instead of a complete replacement, only regular replenishment of the calcite is required to maintain the system's effective function. This filling can easily be done by purchasing calcite in bags from us as accessories.

It is important to note that the frequency of refills depends on various factors, including the water quality and water usage in your home or business. We recommend checking calcite levels regularly and refilling as necessary to ensure continuous and efficient deacidification of your water.

There are important guidelines to follow when using UV disinfection systems for drinking water treatment in Germany. According to a statement from the Federal Health Office, only type-tested systems should be used for drinking water applications and it is recommended that a sensor should be available to display the irradiance.

The systems in the Aquada series from WEDECO, which also includes the Altima, meet the technical requirements, but are not certified by the DVGW (German Gas and Water Association). In contrast, the devices in the Spektron series from WEDECO are DVGW certified. If you want to use a system from the Aquada series in your household, you should therefore coordinate in advance with the responsible authority, such as the health department, to ensure that the use of the device is recognized.

In addition, the Federal Health Office points out that UV irradiation alone does not ensure disinfection of the distribution system (such as water pipes). If there is existing contamination in the pipe network or house installation, disinfection with chlorine is necessary. In this context, we recommend flushing the pipes with our Baxero product to ensure that the pipes are germ-free. This flushing can be repeated annually if necessary to ensure consistently high water quality.
