ISO 9001 Certification
Also we are now a DIN ISO certified company. Aquapro-factory started to introduce the international quality standard in 2016 and successfully completed in August 2017. At the same time, a new, internal quality system was introduced to further reduce the error rate. All our filling plugs are repeatedly inspected for faults during assembly and pressure-tested after installation with a 100% control in order to achieve a constant quality.
