Water softener/descaling system for multi-family homes
A water softener for an apartment building ensures that the water is softer and contains less limescale. This is especially important for protecting household appliances and extending the lifespan of pipes. By reducing limescale deposits, energy costs can be lowered and maintenance minimized. These systems are specifically designed for the needs of larger residential buildings and offer an efficient solution for soft water throughout the entire building. They are easy to install and maintain, making them a practical choice for property managers and owners. Using a water softener not only helps protect the environment but also provides improved comfort when showering, washing, and cleaning. Ideal for a healthy living environment and protecting infrastructure. The advantages at a glance:
- Reduces limescale deposits in pipes and household appliances.
- Extends the lifespan of household appliances.
- It saves on repair costs and energy consumption in the long run.
- Improves water quality for all residents.
- Acquisition and operating costs are tax deductible
How water softeners with salt work
Salt-based water softeners operate using the ion exchange process. In these systems, hard water is passed through a container filled with ion exchange resin. During this process, calcium and magnesium ions, which are responsible for water hardness, are exchanged for sodium ions. The result is soft water that causes less limescale buildup. To keep the system functioning properly, salt must be added regularly to regenerate the resin. This process replenishes the resin with sodium ions, enabling it to remove limescale from the water again. Water softeners are particularly beneficial in apartment buildings, as they not only protect appliances but also increase comfort by extending the lifespan of household appliances and improving water quality.
Advantages of softened water in apartment buildings
As a landlord of an apartment building, you also benefit from tax advantages if you install a water softening system. The purchase price and ongoing maintenance costs, such as regular salt refills, are fully tax-deductible. Furthermore, you have the option of passing on the operating costs of the water softener, including maintenance and operation, to your tenants as part of their utility bill. This not only benefits your tenants with limescale-free water, but also saves you long-term on your property's maintenance costs.
Capacity and performance of dual water softeners
Dual water softeners are ideal for apartment buildings because they provide a continuous supply of softened water. These systems operate with two resin tanks that are used alternately to ensure consistently high capacity and performance. While one tank is regenerating, the other is active, preventing interruptions in the water softening process. The capacity of such systems depends on the number of residents and water consumption . They are particularly effective with hard water and can significantly reduce limescale buildup in pipes and appliances. The constant supply of softened water not only conserves resources but also extends the lifespan of household appliances. Another advantage is their ease of maintenance and operation, making dual water softeners a practical and reliable solution for apartment buildings.
Space requirements and installation in multi-family houses
A water softener for an apartment building requires some space, but the benefits are worth it. It's usually installed in the basement or utility room directly at the main water connection, where there's sufficient room for the unit and the salt reservoir. Easy access during installation is crucial for convenient maintenance and salt refills. A professional will handle the installation to ensure everything runs smoothly. Properly sizing the system is essential to cover the building's water consumption, ensuring all residents benefit from soft water. A well-planned system extends the lifespan of pipes and appliances and saves money in the long run.
Maintenance and care of the water softening system
Proper maintenance and care of a water softener in an apartment building are crucial for the system's longevity and efficiency. Regular inspection and cleaning of the system help prevent limescale buildup and ensure water quality. Regularly check the salt level in the salt container and refill as needed. An annual inspection by a qualified technician can help identify and resolve potential problems early on. Pay attention to leaks and unusual noises that could indicate malfunctions. Clean the system according to the manufacturer's instructions and replace worn parts promptly. A well-maintained water softener provides soft water, protects pipes, and extends the lifespan of household appliances.
Costs and benefits of a water softening system for multi-family homes
Purchasing a water softening system for an apartment building is a worthwhile investment that pays off in the long run. At Alfiltra, we offer complete packages including installation, starting from around €2,000. The exact price depends on the size of the system and the specific requirements of your building. Our complete packages include not only the high-quality water softening system but also professional installation by our experienced team.
The ongoing costs of a water softener are also manageable. Besides the regular refilling of salt, which is necessary every few months depending on water consumption, the running costs are limited to minimal maintenance, which is also easily predictable and tax-deductible. With an Alfiltra water softener, you also save in the long run on expensive repairs and the replacement of limescale-encrusted appliances and pipes. Limescale protection and maintaining the value of your property are our top priorities!

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:
Regeneration process: During regeneration, the resin is flushed with a salt solution, which dissolves and removes the accumulated calcium and magnesium ions (which are responsible for water hardness) from the resin. This “renews” the resin and can be used effectively to soften water again.
Regular cleaning: This regeneration is carried out regularly, depending on the amount of water used and the hardness of the water. In a 4-person household with a water hardness of 20° dH, the system will regenerate more frequently to ensure efficiency.
No replacement necessary: As long as the system is properly maintained and the regenerating salt is topped up regularly, the resin cartridges do not need to be replaced. However, you should regularly inspect and maintain the system to ensure its longevity and optimal performance.
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.
