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


The new noise-dampering technology of push-fit waste systems.

Wide range of diameters from DN 32 mm to DN 160 mm.


The range is composed of pipe lengths from 150 mm to 3 m with one socket, two sockets or smooth pipes without sockets. It features a wide choice of fittings and accessories that allow the most diverse system configurations to be constructed.

Diameters range from the smallest such as 32, 40 and 50 mm for the installation of branches on each floor to larger diameters such as 160 mm for the waste manifolds.

The range is made complete with accessories for connection to other Valsir waste systems, accessories for connection to sanitary appliances and anchor brackets.

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.



Valsir provides complete support both during the planning phase and on site, thanks to a first-class technical office made up of a team of highly experienced engineers, capable of dealing with the most complex system requirements.
