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.

The wastewater can be transported upwards from the system up to 3 m. However, from the highest point, the hose must continue with a gradient of around 2%. In addition, the wastewater should be led into an open outlet (e.g. funnel).

Installing a water softening system requires a certain level of technical understanding and craftsmanship. Installation typically involves installing a bypass valve and connecting to a sewer for regeneration cycles. Special tools and materials are required for installation. This includes pipe cutters, wrenches, Teflon tape and, if necessary, additional pipe fittings and connecting parts.

This is a complex topic that is controversially discussed on the Internet. The first thing that should be mentioned is that these days mainly plastic pipes are used and no corrosion is to be expected.

When water is softened using ion exchange, no CO2 is released and the pH value of the water is not changed. This would look different if the water was treated using reverse osmosis, for example.

It is known that copper pipes are subject to a certain degree of corrosion regardless of the quality of drinking water. However, this corrosion is usually so low that copper is considered a durable material. The low corrosion rate of copper in drinking water results from the formation of a coating on the surface of the material consisting of various copper compounds. This layer is reinforced by small amounts of embedded lime, which increases its anti-corrosion effect. In softened water, this limescale deposit is missing, which can reduce the protective function of the top layer. Nevertheless, the protective effect is sufficiently strong to generally prevent corrosion damage over human generations.

In summary, there is no absolute freedom from corrosion in copper pipes in drinking water systems. Although water softening has an influence on the protective top layer in the pipes, it only has a negligible impact on their service life. If you had problems with corrosion before installing a softening system, then you should think about installing a dosing system or replacing the pipes.

Our basic water softening system meets all legal requirements. The DVGW (German Association for Gas and Water) is an association that issues certificates that confirm compliance with technical standards and safety requirements to third parties. However, a DVGW certificate is not legally required for all applications, which is why our basic system does not have such a certificate.

However, if you require a certificate for your intended use, we are happy to offer you our Leycosoft systems. You can find more information here: Leycosoft 9-15 water softening system carefree package .
