Frequently asked questions about DUPLEX water softening system

The DUPLEX softening system is designed so that the wastewater resulting from regeneration is drained away efficiently, even without the use of an additional pump. Thanks to the plant's advanced design and efficient use of existing water pressure, it is able to pump wastewater to a height of up to 2.5 meters.

This capability allows for flexible installation of the system as the wastewater hose can be connected directly to a higher wastewater pipe without the need for additional pumping devices. This represents a significant advantage by expanding installation options while keeping operating costs low as no additional energy is required for a wastewater pump.

However, please use an open system such as a funnel for the wastewater connection (the hose must be attached to prevent it from slipping out).

Double systems make optimal use of the capacity and require a little less salt, especially when consumption fluctuates. They also provide uninterrupted soft water, but are a little more expensive to purchase.

Double systems make sense in apartment buildings, hotels and in industry if consumption fluctuates greatly and/or soft water needs to be delivered reliably.

It always depends on the number of people and the water hardness, but we generally recommend a double system for apartment buildings.

For a 4-person household with a water hardness of 18-20 °dH, the basic system is generally an efficient choice, especially if there are no large consumers such as a pool. The Basic 40 offers an optimal solution for your needs as it is specifically tailored to water softening in households.

However, it is important to remember that the choice of investment should also take future needs into account. If there is a possibility that additional people could be added to your household, it is advisable to consider a system with a higher capacity to ensure efficient water softening in the long term.

In short, the Basic 40 is a solid and cost-effective choice for your current needs, but the decision should also take potential future needs into account.

Yes, our duplex systems are perfect for such applications.

The duplex can manage apartment buildings with irregular water consumption, large garden irrigation, pools, etc. without any problems. However, it depends on the right capacity.

You can either use our calculator or we will be happy to make you a suitable offer and find the right system for you.

You cannot screw it directly to the wall as the plastic would not be able to withstand the weight of the salt.
Of course, you can screw a pedestal or shelf onto the wall that supports the specified weight and place the container on it. How heavy the salt container is depends on the size of the system. You can find this data in the technical data sheet.
