BWT water filter system

Jandelsbrunn. An unknown graffiti artist once fittingly noted: Standing water stinks. The transparent chemical compound with the known by the formula H2O is often underestimated, although it is the world’s number one foodstuff. Almost anywhere in Germany, you can drink tap water without giving it a second thought. The water is carefully cleaned and continuously controlled by the health inspection agencies. The German Federal Drinking Water Ordinance dictates very rigid pollutant limit values. Because: Clean water is a symbol for health and quality of life – even while travelling.

However, what happens when you take trips to faraway countries and regions, where the quality of tap water is questionable, at best? For those customers who have purchased a Knaus Tabbert caravan, there is nothing to worry about: from the 2020 model year forward, the space‐saving BWT water filter system ensures that you have the cleanest water while travelling. BWT stands for „Best Water Technology‟. The company, based in Schriesheim (Germany) near Heidelberg, is specialized on water treatment, purification and filtering.

Beginning with model year 2020, the water in Knaus Tabbert vehicles will be filtered and thereby be clean, soft and pleasant to taste. Positive side effect: there are fewer calcium stains in the shower and in the sink. What’s more: this doesn’t just benefit the new vehicles: The BWT water filter system can also be retrofitted in older Knaus Tabbert models.

The number of substances that contaminate drinking water is high. Pathogens, chlorine or suspended particles cause problems.

In addition, the pipes, hoses and tanks of motorhomes and caravans are not normally flushed regularly, so that over time deposits and bacteria can form. Water that has remained in containers and pipes for too long will not stay fresh. Above all, heat causes a film to form in the water tank. This provides an ideal breeding ground for microorganisms. Under these conditions, even germs multiply significantly faster.

These germs can also infiltrate the pumps and fittings. If the water remains standing for just a few days, this is usually unproblematic. However, the water will quickly develop a stale taste. For those who take their caravan into warmer regions, they must be aware that the warmer is gets, the more germs will be generated if the water stays in the tank too long. Only if water is stored in an air‐tight container, then it can be used for an almost unlimited period of time.

Regular cleaning and disinfection of the fresh water tank reduces the risk of bacterial contamination. This type of cleaning should be performed twice a year. Depending on the age and condition of the water system, special cleaning and descaling agents are available from specialist dealers. Today, the use of so‐called silver ions to combat germs is controversial. According to the most recent interpretation of the Drinking Water Ordinance, at least soluble additives containing silver chloride are considered problematic. It’s a good thing that Knaus Tabbert now prevents this with the standard BWT water filter – ensuring that standing water is no longer stinks.
