    Z: 7.5–9.0 litre/minute

    A: 13.5–15.0 litre/minute

    S: 18.0–19.8 litre/minute

  • k

  • KTW approval

    Components made of organic materials that are used in a mixer tap and come into contact with drinking water must have KTW approval (KTW = plastics in contact with drinking water) from the German environmental protection agency (Umweltbundesamt). Health and hygiene regulations are detailed in guidelines, e.g. for organic materials such as plastics, lubricants like valve lubricant or elastomers used in O-rings and gaskets.

    Further requirements to protect drinking water from microorganisms on non-metallic materials are stipulated in the worksheet from the DVGW (DVGW = German Association for the Gas and Water Industry). Materials for seals have to comply with this technical standard, where the product is examined for its long-term microbiological behaviour in a material test. This ensures proof of these materials’ safety for use with drinking water, in particular avoidance of biofilms.

  • Noise class

    Classification of mixer taps according to specific standards depending on how much noise they make.

    All mixer taps used in multi-occupancy properties have to comply with DIN 4109 (sound insulation in buildings).

    They are divided into two noise classes depending on the level of noise.

    Noise class I: Emitted noise < 20 dB (A)

    Noise class II: Emitted noise < 30 dB (A)

    High-quality mixer taps are thus distinguished by their classification in noise class I. They have a built-in silencer to reduce noise levels. A “quiet” mixer tap can be identified by the P-IX... noise inspection symbol.

  • 5f574

  • Thermal disinfection

    Method for eradicating Legionnaires’ disease (life-threatening bacteria) from plumbing in houses. To achieve this, the water heater needs to be operated so that the hot water flowing through the pipes still has a temperature of 70 °C. The risk of scalding should be taken into account, or it should be done at times when there is less consumption of hot water. To perform this effectively, hot water tapping points should be opened for at least 3 minutes. This helps to flush the pipe and the tap simultaneously, to disinfect them thermally and it kills the Legionnaires’ disease.
