Valsir PP3® ensures a practical and rapid installation without the use of glues or special tools thanks to the jointing system with push-fit sockets.
The particular shape of the seal and the housing of the push-fit joint guarantee hydraulic tightness and allow the normal movements of the pipe including those caused by thermal expansion.
the thermal expansion of Valsir PP3® is extremely low compared to the most common plastic materials, a 3000 mm pipe will expand in length by just 13 mm when the waste liquid flows at a continuous temperature of 60°C.
It is thanks to this low coefficient of thermal expansion that the push-fit joints are capable of absorbing the variations in length of the pipe without taking any particular precautionary measures; it is enough to follow the installation instructions in the Valsir technical manuals.
To allow the use of leftover pieces of pipe, Valsir supplies a bi-joint sleeve. This is a special fitting that allows two pipes without sockets to be connected guaranteeing hydraulic tightness without compromising flow rates.
When a waste system is in use, noises are generated inside the pipelines causing it to vibrate from the fall of the liquid being discharged
Most of the noise generated spreads inside the pipe but the vibrations that are generated are transmitted from the walls of the pipe to the surrounding area and to the bracketing systems and consequently to the building structure.
To minimize noise levels in waste and drainage systems, not only should the system be properly designed and the waste circuit be mounted correctly, but it is also important to choose a system with an elevated soundproofing performance.
PP/PP3® allows waste systems to be installed that guarantee excellent soundproofing performance, with 2 l/s (typical toilet flush) noise emissions of 17 dB(A) were measured.
The reference standards used to evaluate the performance of waste systems in the laboratory and which specify the measurement methods are German Standard DIN 4109 (together with DIN 52219) and European Standard EN 14366.
Both standards require the use of a four-storey building with an inside wall in concrete to which the waste stack is anchored.
The measurement floors are divided into two rooms: the front room is where the waste stack is installed, the rear room has no pipes running through it but receives the sound vibrations in the partition wall. The values measured can be expressed with different indicators depending on requirements and the reference standards.
LSC,A is the indicator required by EN 14366 and indicates the structural-borne noise level transmitted whereas LIN is an indicator that also takes air-borne noise into consideration required by DIN 4109.
It doesn’t matter which indicator is more important, the aspect that needs to be taken into consideration is that in order to compare different waste systems the same indicator must be used.
The actual noise levels of a waste system can only be measured on site, in that noise emissions depend on numerous factors, such as the installation and the type of building; laboratory indicators are only to be used as a means of comparison.
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.
Guide points are created using brackets which, as well as supporting the weight of the pipe, they also allow the axial movement of the pipe, preventing it from flexing due to the increases in length caused by heat expansion, following increases in the temperature of the room and the waste water.
Guide points are created when the bracket is not tightened completely around the circumference of the pipe, giving it free axial movement.
Fixed points are also called anchor points and are created in order to prevent any movement of the pipe in the area where the bracket has been fixed. The aim of the fixed point is to divert the variations in length of the pipe in the desired direction, that is, towards the ring seal sockets, the expansion sockets or towards the compensation deflection arms.
Fixed points are usually achieved by using suitable brackets that are closed tightly around the circumference of the pipe.
Valsir Collarwings is the new range of fire-stop sleeves produced in compliance with the most recent standards and suitable for different types of plastic pipes. Collarwings fire-stop sleeves are made of steel that is painted using polyester powder, coupled with special intumescent elements that, in the presence of fire, expand and squeeze the pipe thus preventing the passage of flames, vapour and combustion gas and acting as a form of thermal insulation.
The seal is completely inaccessible thanks to the particular shape of the housing.
The joint guarantees total bore passage thanks to the absence of reductions in the section.
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.

Valsir PP3® is a waste system made up of pipes, fittings and accessories for the construction of waste and rainwater drainage systems.
Valsir PP3® is an extremely light system and thanks to the push-fit socket with hydraulic seal it represents the most simple solution for the construction of waste and drainage systems.
Valsir PP3® is manufactured to European Standard EN 1451 and can be used for waste systems at low and high temperatures, ventilation systems for waste networks and for rainwater drainage systems inside buildings for civil and industrial use, hospitals and hotels.
The wide range of pipes, fittings and accessories allow the entire waste network to be made, from the branches to sanitary appliances to the stacks and waste manifolds.
To facilitate video inspection operations.
High impact resistance at extremely harsh temperatures below 0°C.
Wide range of diameters from DN 32 mm to DN 160 mm characterised by triple layer pipes and single layer fittings.
Corrosion and abrasion resistance.
High chemical resistance to the substancesdissolved in civil and industrial waste waters
Wide range of transition fittings for connection toother waste systems such as cast iron, PE, PP, PVC.
The EPD statement is available to certify the reduced environmental impact associated with PP3 according to the full life cycle assessment, or "cradle to grave". This means that our monitoring and optimisation efforts do not only cover the production stages: PP3 is a champion of sustainability from the extraction of its raw materials to the disposal of the product itself. Choose it for your project and get credits for Green Procurement sustainability protocols (e.g. LEED V4)!
