Quality & Safety

Drinking water taken directly from the tap is by far the best controlled food in Germany. No other basic foodstuff has to meet such high quality requirements and undergo such detailed analyses.

Especially for this reason and since it is our responsibility vis-à-vis the customer, the entire workflow in our company is oriented towards quality. This begins with the office administration and expands to our experts on site who are in charge of the work associated with repairing the drinking water pipes. Upon request, the customer is provided with comprehensive documentation material that is produced during the repair phase.

Our company as well as the DonPro method have been certified to DIN ISO 9001:2000 and NSF. At this point, we would also like to point out that the method we developed and introduced meets the provisions of the German ordinance on the treatment of drinking water and that it is regularly monitored by accredited labs.

Even though internal pipe repair cannot be compared with the installation of new pipes, we assume a service life of 20 to 25 years. Like for new pipes, we offer a 5-year warranty for internal pipe repair.
