Answer: There is no obligation for such a measurement because the water complies with the Drinking Water Ordinance either way. As a rule, it is sufficient to check the system every 12 months as part of maintenance.

Answer: Of course, we are happy to offer you a backwash filter. This should definitely be installed to protect the system.

Answer: The frequency of refilling salt in a DUPLEX water softener depends on various factors, such as the water hardness in your area, the water consumption of your home or business, and the capacity of the system's salt tank. Here are some general guidelines that can help you estimate how often you need to refill the salt: Water hardness: The harder the water, the more salt is needed for the ion exchange process to soften the water. Water consumption: Higher water consumption leads to more frequent regeneration cycles, which in turn means more salt consumption. Salt container capacity: Larger salt containers need to be refilled less frequently. Check the capacity of the salt container of your DUPLEX system. Average Salt Consumption: In general, household water softeners use about 125 grams of salt per regeneration per cubic meter of soft water. To get a more accurate assessment, you can consider your daily or monthly water consumption and water hardness. As a rule of thumb, in an average household the salt in the softener should be replenished approximately every 6 to 12 months. However, it is important to check the salt level regularly and top up the salt as needed to ensure continued efficient water softening. Please refer to the technical data sheet for the exact salt consumption or use our capacity calculator to calculate the approximate consumption.

Answer: At the beginning of the installation, the installer will briefly turn off the water until he can install the connection fitting. Water will then be available to you as usual again and it will no longer need to be turned off for further installation.
