valsir

Valsir is an Italian manufacturer specialising in advanced drainage, waste, and water management systems for residential, commercial, and industrial construction. The brand is best known in the UK for its Triplus soundproof waste pipe system, which is widely specified on high-density housing, apartment blocks, hotels, and healthcare projects where acoustic performance is a priority. Valsir also produces HDPE drainage systems, siphonic rainwater drainage, underfloor heating solutions, and push-fit piping for hot and cold water distribution. All Valsir products are manufactured in Italy and engineered to meet international standards including EN 14366, EN 1451-1, and ISO quality management requirements. The company invests heavily in research and development, holding multiple patents across its core product ranges. Valsir systems are available through MP Moran at competitive trade prices, with next working day delivery available on stocked lines.

Triplus is Valsir's flagship triple-layer soundproof waste and drainage system, designed for use inside buildings where acoustic performance is a specification requirement. Each pipe is constructed from three distinct layers: an inner and outer shell of polypropylene (PP) for chemical and mechanical resistance, and an intermediate layer of a patented PP and mineral filler (MF) compound that provides the acoustic dampening properties. The push-fit connection method means no glues, solvents, or special tools are required on site, which reduces installation time considerably on busy projects. Independent acoustic testing confirms noise levels of 12 dB(A) at a flow rate of 4 litres per second, measured in compliance with EN 14366 and certified by the Fraunhofer Institut für Bauphysik in Stuttgart. Available in diameters from DN 32mm to DN 250mm, the system covers the full range of internal waste stack applications from basin wastes through to main soil stacks. Triplus connects directly to existing cast iron, PP, and PVC systems, making it equally suitable for refurbishment as it is for new build.

Standard PVC and polypropylene waste pipes transmit the sound of flowing water directly through the pipe wall and into the building structure, which becomes particularly noticeable in multi-storey residential and hospitality buildings. Soundproof systems such as Valsir Triplus are engineered to absorb and dampen vibrations within the pipe wall itself, significantly reducing the noise transmitted to surrounding walls, floors, and ceilings. For soil and vent pipe installations in apartment blocks, hotels, and student accommodation, acoustic drainage is increasingly written into project specifications by architects and acoustic consultants. Building Regulations Approved Document E sets requirements for airborne and impact sound insulation in residential buildings, and specifying a low-noise waste system supports compliance on sensitive projects. The labour cost difference between installing a standard system and a push-fit soundproof system like Triplus is minimal, given that no additional tools or adhesives are required. For any project where occupant comfort or planning conditions place demands on acoustic performance, specifying a dedicated soundproof waste system is the professional standard.

The Valsir Triplus range covers nominal diameters from DN 32mm up to DN 250mm, providing full coverage across both small-bore waste applications and large-diameter soil stacks. Commonly stocked sizes at MP Moran include 75mm and 90mm for branch waste runs and 110mm for main soil and vent stacks, which are the sizes most frequently required on residential and light commercial projects. The range includes straight pipes in multiple lengths, along with a comprehensive selection of bends, branches, reducers, access fittings, and couplings to complete a full system installation. Pipes are available in single-socket and double-socket formats, and short lengths are stocked for use in tight spaces or riser installations where full lengths cannot be accommodated. Larger diameters in the Triplus range are available for commercial and industrial applications where higher flow rates are required. Speak to the MP Moran trade counter team if you need to confirm availability on specific sizes for your project.

Yes, Valsir Triplus is designed to connect with other common drainage materials including cast iron, standard polypropylene (PP), PVC, and polyethylene (PE) systems. This makes it a practical choice for refurbishment projects where existing pipework in a different material needs to be extended or tied into a new installation. Transition couplings and adaptors are available within the Triplus range to facilitate connections between Triplus and dissimilar pipe materials at the correct diameters. The system's push-fit socket connections use elastomeric seals that accommodate minor positional adjustments during installation, which is useful when connecting into existing pipework that may not be perfectly aligned. Triplus pipes have a low coefficient of thermal expansion, which reduces the need for the expansion joints that are sometimes required with standard PVC systems in tall buildings. Always verify the correct transition fitting is selected for the specific pipe material and diameter being joined to ensure a watertight connection.

Yes, the Triplus system is suitable for both soil (WC discharge) and waste (basin, bath, shower, and sink discharge) applications within buildings. The range includes the full range of fittings needed to construct a complete above-ground drainage stack, from small-bore 32mm waste branches through to 110mm main soil and vent pipes. Triplus pipes are certified to EN 1451-1 for thermoplastic piping systems for soil and waste discharge, confirming their suitability across the full spectrum of internal drainage applications. The system can handle intermittent discharges at temperatures up to 95°C, making it suitable for commercial kitchen waste connections as well as standard domestic applications. It is also rated for waste waters with a pH value between 2 and 12, giving it strong resistance to the chemical compounds commonly found in both domestic and light industrial wastewater.

Triplus uses a push-fit socket connection system, which means installation requires no solvent cement, open flames, or specialist tools beyond a pipe cutter or saw and a deburring tool. The process is straightforward: measure and cut the pipe to length, deburr the cut end to remove any burrs or sharp edges, and push the spigot end into the socket until it seats correctly against the elastomeric seal. Pipe clips and brackets should be positioned at the spacings recommended in the Valsir technical guidance to support the system correctly and prevent sag on horizontal runs. For vertical soil stacks in multi-storey buildings, fire collars or intumescent pipe wraps will be required at floor penetrations to maintain the fire compartmentation of the building in line with Building Regulations Approved Document B. The low coefficient of thermal expansion of Triplus reduces the number of expansion joints needed compared to standard PVC systems, simplifying the installation layout. Valsir provides detailed installation and design guidance including dimensioning calculations, which are available on request from the MP Moran trade counter team.

Valsir Triplus is engineered to handle intermittent discharges at temperatures up to 95°C, making it suitable for connecting to commercial dishwashers, industrial process equipment, and other high-temperature waste sources in addition to standard domestic drainage. The system can also withstand impact and structural loads at temperatures as low as -25°C, which is relevant for installations in unheated plant rooms, external riser enclosures, and cold-climate environments. The smooth internal bore of the pipe prevents the build-up of deposits, which is beneficial for long-term flow performance in both domestic and commercial applications. In terms of chemical resistance, Triplus can transport waste waters with a pH value between 2 and 12, covering the range of acids and alkalis found in most civil and light industrial wastewater streams. The outer polypropylene layer also provides strong resistance to corrosion, abrasion, and mechanical impact, which protects the pipe during construction and throughout its service life. These combined performance characteristics make Triplus an appropriate specification for demanding environments beyond standard residential use.

Yes, Valsir Triplus is specifically designed to perform in multi-storey residential, commercial, and hospitality buildings where acoustic performance, structural reliability, and ease of installation in confined risers are all important. The system's soundproofing properties make it a common specification on high-rise apartment schemes, purpose-built student accommodation, hotels, and hospital ward refurbishments where noise from drainage stacks would otherwise transmit between floors. Triplus has a low coefficient of thermal expansion compared to standard PVC, which reduces the frequency of expansion joints required on tall stacks and simplifies the installation design. The range of available diameters up to DN 250mm supports the higher flow rates required in large commercial buildings with multiple WCs and waste connections served by a single stack.

BIM files for Valsir Triplus components are available for design teams working in Revit, supporting integration into the building model from early design stages.

Valsir Triplus is manufactured in accordance with Green Building principles, and the material is fully recyclable at the end of its service life. The production processes used by Valsir are certified under ISO 50001 for energy management, and the company holds ISO 9001 quality management certification across its manufacturing operations. Triplus is one of a very small number of drainage systems in the world to have been awarded a LEADER rating by the Green Building Council of Singapore, reflecting its strong environmental credentials in the context of international green building assessment frameworks. The push-fit installation method eliminates the use of solvent cements and chemical adhesives on site, reducing the use of volatile organic compounds (VOCs) during construction. The long service life of the system also reduces material replacement demand over the lifespan of a building compared to less durable alternatives. For contractors and developers working to BREEAM, LEED, or other sustainability assessment criteria, Valsir Triplus is a specification that supports environmental performance targets on drainage systems.
