BWT dosing units add a small amount (approx. 3 mg/l) of minerals to the drinking water in line with current water consumption. (Limit value of the drinking water ordinance: up to 5 mg/l). The minerals form a protective layer in the pipe which separates the pipe material from the water (inner pipe sealing). Existing sources of corrosion can be infiltrated and thus stopped. The inner pipe sealing can thus become a life insurance for your pipe installation, which is destroyed without appropriate protection and causes high consequential costs (pipe bursts, pipe replacement).
