Our water filter FAQ - for more answers
What is reverse osmosis?
Reverse osmosis is a unique filtration process that filters out pollutants in the molecular/nanometer range. In reverse osmosis, tap water is forced through a fine-pored, semi-permeable membrane. This membrane consists of laser-perforated, ultra-fine pores, which ensure that the water molecules are pressed through the membrane, thus retaining up to 98.2% of dissolved foreign substances.
I live in a very calcareous region (high water hardness). What do I have to consider?
In regions with a high lime content in the water (from 12°dH - German hardness), a special lime pre-filter should be installed so that the UO membrane is not damaged or clogged prematurely. The lime pre-filter can of course also be found in our store under accessories.
How does the filtered water taste and does it affect the taste of coffee/tea/juices/concentrates?
The filter system removes all contaminants from the water that previously had a negative impact on the natural taste of hot and cold beverages. In the future, your drinks will taste even more natural and intense under optimal conditions, as they will be free of unwanted substances. Here you can read what 8 reasons there are for a water filter.
How much filtered water does a plant produce?
Under optimal conditions, i.e. sufficient water pressure (min. 3 bar), optimal installation site, etc., a system (e.g. our AS5000) produces between 150-190 liters of filtered water per day.
When should the equipment be disinfected?
We recommend you to disinfect the filter system every 3-6 months. Read more about our disinfectants here.
What should I keep in mind when not using the device for a long period of time?
If the filter system has not been used for a longer period of time, e.g. after a longer vacation, drain the water supply tank for hygienic reasons and rinse the filter system. Important: If the unit is not used for a longer period of time, the membranes and the filters must be kept moist so that they do not dry out. We also recommend disinfection to prevent the formation of germs and biofilm in the entire filter system. You can see exactly how this works in one of our instructional videos for water filters.
The water tastes bad. What can be the reason for this?
Remember to change your filters regularly. Replace your filters and drain and flush the water supply tank. A water revitalization filter, such as the Vital Filter or Fresh Filter can additionally improve the taste of the water.
1st problem: After the first installation of the filter system, no water flows from the tap.
Solution: First check that the cold water connection is turned on and that the lever on the supply tank connection is open. Remember that it may take some time for the filtration system to produce enough water to build up the operating pressure to ensure optimum water pressure in the water supply tank. Check to see if a hose is kinked. Kinks in the hoses should be avoided at all costs.
If water still does not come out, go through the installation instructions a second time, step by step, and make sure you have done everything correctly. If the problem persists, please contact us.
2nd problem: After changing the filter, no water flows from the tap?
Solution: Open the cold water connection and the tank connection.
If necessary, also make sure that you have inserted the activated carbon filter (GAC) into the housing "2" with the white ring facing upwards.
3rd problem: The water jet is too weak.
Solution: If the tank pressure is below 0.5 bar, you can change it by increasing the air pressure at the water supply tank using an air pump. Important Check the air pressure beforehand using an air pressure gauge (article no.: TD3). Since an excessively high air pressure could damage the water supply tank. Proceed with caution. To do this, loosen the blue cap and screw a car air pump onto the valve. After pumping a few times, check that the water pressure is sufficient by opening the tap or using an air pressure gauge.
4th problem: My water tank does not produce the specified amount of water.
Solution: The tank capacity of 8 liters indicates the gross water volume. The net volume of water is approx. 6 liters. The remaining 2 liters of volume are distributed over an air cushion. This regulates the air pressure.
5th problem: the water pressure in my apartment/house is below 3 bars.
Solution: The filter system is designed for a water line pressure of 3 to 6 bar. At a lower pressure, the amount of water filtered and the water quality will decrease. In countries outside Germany, the water pressure is often lower. In this case, you must install a booster pump.
6th problem: The water pressure in my apartment/house is over 6 bar.
Solution: If the water line pressure is too high, the system and the diaphragm may be damaged. In this case, you should install a pressure reducer.
7th problem: the tank does not fill.
Solution: Check the pressure in the tank to make sure it is not too low. The optimum pressure should be 0.5-0.9 bar, when empty. Increase the pressure as described in point 3.
8. problem: the filter system produces only waste water.
Solution: This happens very rarely and is a sign that the automatic shutdown may be defective. Please contact us in this case.
9th problem: the water has a bitter aftertaste.
Solution: Remove the water hose from the upper corner piece of the membrane housing. Now follow the hose to the automatic switch-off and turn it off at the automatic switch-off. Now fill a glass with this water. Taste the water and measure the conductivity with a TDS tester. If the water tastes good and the conductance shows a value of 1-50ppm, a defective afterfilter may be the cause of the bitter aftertaste. In this case contact us.
10th problem: colored water flows out of the faucet during the first start-up.
Solution: This is normal. The activated carbon filter must be soaked. The filter system must be flushed. Flush the system one more time.
11. Problem: Der Dichtungsring der Membrane sind trocken.
Lösung: Sind die Dichtungsringe trocken und porös, sollten sie durch neue ausgetauscht werden. Sind die Dichtungsringe noch nicht sehr alt (1-2 Jahre), können diese auch leicht angefeuchtet werden, damit sie besser in das Gehäuse passen und es somit wieder effektiv abdichten können.
