Latest Questions
Product: GUTZZI under-sink reverse osmosis system
Answer: Precisely because the system is very compact, changing the filter is relatively uncomplicated. You turn off the water and can then place the entire system on the sink or take it outside. Only the water that is in the hoses comes out.
Product: DUPLEX water softening system in a carefree package
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.
Product: LOWARA small pressure booster system BGM 9/A
Answer: The pump can be used for this without any problems. We would be happy to advise you on this, including regarding storage tanks etc.
Product: PENTA multi-filter system
Answer: First the 80 μm pre-filter is installed, then the Penta system and then the carbon followed by the 20 μm sediment filter.
Product: Key for filter housing 2-1/2"
Answer: The key is made of plastic.
Product: 20 liters of demineralized DI water in the canister
Answer: Our water is suitable for this and is also used by many plumbers. You are also welcome to discuss this with your installer; the data sheet with the water specifications can be found on the product page under Downloads. Alternatively, the water can be treated on site using a mixed bed cartridge.
Product: ZIP reverse osmosis system
Answer: The question is not easy to answer, generally the ratio is 50/50. Since you don't have to empty the water (it collects back in the container) but only fill it up with new water, you can continue to process the other 50%. Only after the 10th run should you refill the basic tank.
Product: REOS Plug & Play reverse osmosis system with softening system
Answer: Basically, you can connect the system as it is delivered to the water, wastewater and electricity and produce water directly. We also offer various accessories such as storage tanks if necessary. That depends on your requirements. We would be happy to create an individual offer.
Product: BASIC softening plant
Answer: 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.
Product: REOS Plug & Play reverse osmosis system with softening system
Answer: This depends on the respective model. Here are a few calculations (under optimal conditions): The model with an output of 150 l / h needs almost 7 hours for 1 m³ of water with a power consumption of 0.5 kW. This corresponds to approximately 3.6 kWh per m³. The model with 300 l / h output therefore needs approx. 3.5 h for 1 m³ of water with a power consumption of 0.65 kW. This corresponds to approximately 2.16 kWh per m³. The model with 600 l / h output, on the other hand, needs less than 2 hours for 1 m³ of water with a power consumption of 2.2 kW. This corresponds to approximately 3.6 kW per m³.
