Prefabricated plumbing

Innovative plumbing technology consisting of prefabricated, universally applicable plumbing boxes and pre-wall installations, which we offer in connection with the plumbing technology manufacturer MEPA, making up our comprehensive product portfolio.

Plumbing box

For every installation situation
The principle of our plumbing boxes: no more masses of individual components, just one 100% pre-assembled and pressure-tested component for plumbing connections with millimetre precision.

Connections in the blink of an eye
The advantage of prefabricated plumbing boxes is the significant time saving and added safety. The result: you install three sink connections in the time it normally takes to install one – thermal insulation, sound insulation and condensation protection included.

Pre-wall installation

Holistic plumbing technology
The combination of the MEPA pre-wall system and RAUTITAN for the drinking water installation and RAUPIANO PLUS for the house connection creates a perfectly harmonised system. The universal system for RAUTITAN is lead-free with no O-rings. "RAUPIANO PLUS" offers excellent sound absorption and, due to innovative fire protection solutions with zero clearance, enables installation that saves a lot of space.
