Pipe you can hold to the specification.
A pipe is buried, cast into a slab or run inside a wall, and it is judged years later. What follows is what Wasser does before that, and what the numbers on the box are worth.
Why choose Wasser Pipes
Reasons that come with a specification attached
Each point below is drawn from the Wasser Pipes technical data, and names the pipes it actually applies to.
A pipe for each job, not one pipe for everything
Eleven systems across PP-R, HDPE and PVC-U, with drainage colours assigned to specific installation positions — golden brown underground, grey above ground, white for both.
Whole range
Corrosion and chemical resistance
PVC-U pressure pipes are immune to chemical, electrolytic and galvanic action. PP-R pipes resist corrosion and aggressive environments, and offer excellent resistance to acids, alkalis, oils and domestic effluents.
PVC-U Pressure · PP-R
Smooth internal surfaces for efficient flow
PP-R pipes have a slippery, bright internal surface so sediments and impurities are not observed. SWR and acoustic drainage pipes have a mirror smooth, restriction-free bore that keeps the system free from clogging and drain choke-up.

UV-protected options for outdoor runs
PP-R UV Protected and PP-R UV Composite pipes carry a UV protected layer of UV resistant materials, which protects the pipe from flaking when exposed to sunlight over time.

Thermal-insulated pipe where heat loss matters
The PP-R Thermal Insulated pipe is built with an insulating middle layer to attain better thermal resistivity than standard PP-R pipes, for hot and cold water.
PP-R Thermal Insulated
Acoustic drainage that measurably reduces noise
The PVC-U Acoustic pipe uses a middle hollow grid layer in the 110 mm and 160 mm sizes to reduce noise levels by more than 6 dB, while internal vanes reduce vortex and direct the flow.
PVC-U Acoustic
Pressure-rated water supply
HDPE and PVC-U pressure pipes are produced in PN6 to PN20. PP-R Composite and UV Composite pipes are rated to 25 bar, and the published data shows how those pressures reduce as temperature rises.
