Valsir S.p.a
Waste and water
supply systems, underfloor heating system
and flush cisterns


The evolution of push-fit soundproof waste systems.


The range is composed of pipe lengths between 150 mm and 3 m and is characterised by a wide choice of fittings and accessories that allows the construction of the most varied system configurations.

The smaller diameters such as 32, 40 and 50 mm are used for the branch pipe connections on each floor, while the larger diameters such as 250 mm are used for the waste manifolds.

The range is completed with accessories for the connection to other Valsir waste systems and pipe clips, which, when fitted with anti-vibration rubber, allow reduction of the vibrations that are transferred to the installation walls when the waste system is in use.

An extremely wide range

Wide range of diameters from DN 32 mm to DN 250 mm.


Accessories for all installation requirements


Surface mounting of pipes requires the use of suitable brackets that must withstand the weight of the pipe, the weight of the waste water and the forces that are generated by expansion and contraction. In relation to the type of bracketing chosen, the so-called guide points and fixed points (or anchor points of the pipeline) must be provided.

In all cases, if the waste system is required to reduce noise then sound reducing brackets with anti-vibration rubber must be used.

If the waste system is constructed using Triplus® or Silere® then the employment of sound insulating pipe brackets is essential

Solutions for all requirements

Valsir is the only company that can supply a triple layer waste system with a Triplus® “ventilation branch”. This is the ideal solution in high-rise buildings with a high simultaneous use factor of the sanitary appliances.

This innovative waste system guarantees excellent ventilation of the stack and branch connections on each floor thus limiting pressure fluctuations within the system.
