PPS water supply lines for taps comply with the latest drinking water standards

The interplay of complex, precision components

Drinking water is the most strictly regulated foodstuff in Europe. And those standards are constantly being tightened. From 2028, the use of lead in brass will be so strictly limited that permitted alloys will be almost impossible to machine. Thanks to complex water supply systems made from PPS, the German tap manufacturer Grohe is able to replace lead-containing brass with plastic.

  • High-performance plastics for drinking water applications

  • Complex assemblies for continuous water supply systems

  • Top-quality moulds for maximum precision

Results to be proud of

High-performance PPS-GF40 with accuracy to the nearest hundredth

When replacing brass, we frequently use PPS-GF40, a very high-quality material containing 40% glass fibres. The complex geometries of the components, which are formed in the mould by numerous moving cores and slides, must meet tolerances of a few hundredths of a millimetre.

Modern solutions for drinking water standards

As specialists in the plumbing industry, we are fully aware of the standards and requirements governing drinking water. Working in partnership with our customers, we help develop modern solutions to meet increasingly stringent standards.

Over 35 moulds in 2 years

In recent years, Grohe has converted several tap ranges into hybrid products featuring plastic waterways and brass exteriors. To this end, we have developed more than 35 precision moulds in a short space of time.

How did we achieve this?

We have now built up a wealth of expertise in the production of drinking water liners. A specialist project manager oversees all projects from the initial design stage through to the construction of the moulds and the start of production. In addition to our in-house mould-making facility in Germany, we have a specialist partner in Asia with whom we carry out these large-scale moulding projects.

No mechanical processing

Despite the high level of complexity of some parts of the water-carrying system, these components emerge from the mould ready for use. Holes, threads and fits are so precise that no further machining is required. This results in significant savings in machining costs.

A fully-fledged alternative to brass

The PPS material, reinforced with 40% glass fibres, is rock-hard and extremely strong, and feels almost like metal. This makes it a worthy alternative to brass, without compromising the tap’s strength. And because several types of PPS have drinking water certifications (including KTW-BWGL and WRAS), these components are a reliable alternative to brass in drinking water applications.
