A building's plumbing and drainage infrastructure is one of the most important parts of its overall construction. Although these systems remain largely hidden after completion, their design, material quality and installation can have a significant impact on the long-term performance, comfort and reliability of a building.

Valsir is an Italian manufacturer specializing in advanced plumbing, drainage, heating and building-service solutions. Established in 1987 as part of the Silmar Group, Valsir has developed a broad product portfolio covering waste and drainage systems, water distribution, WC flushing systems, radiant systems, rainwater drainage and ventilation solutions.

For residential buildings, hotels, hospitals, commercial developments and industrial projects, selecting the right piping and drainage system is an important part of the MEP design process.

As a Valsir product supplier, we provide product supply, project assistance and technical support to help contractors, consultants, architects, developers and procurement teams identify suitable Valsir solutions for their projects.

Valsir Waste & Drainage Systems

Drainage systems need to transport wastewater efficiently while maintaining durability, hygiene and appropriate acoustic performance.

Valsir offers several drainage technologies, including HDPE, PP3, Blackfire, Triplus, Silere, Airval and related components and accessories.

Different systems are designed for different project requirements, allowing engineers and contractors to select the appropriate solution according to building type, installation conditions and performance requirements.

Valsir HDPE Drainage System

Valsir HDPE is a welded high-density polyethylene drainage system designed for waste and rainwater drainage applications.

The system includes pipes, fittings and fixtures and can be used for above-ground, underground and concrete-embedded installations. Valsir highlights the material's resistance to UV exposure, chemicals, mechanical stresses and abrasion.

The HDPE system is available in diameters from DN 32 mm to DN 315 mm, with different thickness options depending on the application. Valsir also provides a range of interconnection fittings for integration with other drainage systems.

For large residential, commercial and industrial projects, HDPE can provide a robust option where welded drainage connections and strong mechanical performance are required.

Valsir PP3 Drainage System

PP3 is a lightweight polypropylene drainage system designed for waste and rainwater drainage applications.

The system uses a three-layer pipe construction and push-fit socket connections with hydraulic seals. Valsir states that PP3 is manufactured according to EN 1451 and can be used for waste systems, ventilation systems and rainwater drainage within civil and industrial buildings, hospitals and hotels.

PP3 is available in diameters from DN 32 mm to DN 160 mm and is designed with features including chemical resistance, impact resistance and compatibility with connections to other drainage materials.

Its lightweight construction and push-fit installation approach can make it particularly useful for projects where installation efficiency is an important consideration.

Valsir Acoustic Drainage Systems

Noise from wastewater flowing through drainage pipes can become a significant comfort issue in residential buildings, hotels, hospitals and other occupied spaces.

Valsir's portfolio includes acoustic drainage solutions designed to address this requirement.

Silere, for example, is an acoustic drainage system developed specifically to reduce noise generated by wastewater systems. Valsir describes it as a system focused on very high acoustic performance.

For projects where occupant comfort and acoustic performance are important design considerations, specifying an appropriate acoustic drainage system can be an important part of the MEP strategy.

Valsir Water Distribution Systems

Beyond drainage, Valsir also provides systems for water distribution and plumbing installations.

Its supply-system portfolio includes solutions such as:

PEXAL

MIXAL

THERMOLINE

PEXAL BRASS

BRAVOPRESS

PEXAL XL

PEXAL EASY

PEXAL TWIST

CONNEX-T

PEXAL FIX

These systems are intended for different water-distribution and plumbing applications.

PEXAL Multilayer Piping

PEXAL is one of Valsir's multilayer piping systems, using cross-linked polyethylene and a butt-welded aluminium layer.

Valsir describes PEXAL as a system for water distribution applications and provides dedicated fittings and components for creating complete installations.

For engineers and contractors, selecting the appropriate multilayer piping configuration depends on factors such as application, operating conditions, installation method and project specifications.

Valsir WC Cisterns & Flushing Systems

The flushing system is another important component of modern bathroom construction.

Valsir provides concealed and exposed WC flushing solutions along with control plates and related components.

Its portfolio includes systems such as Tropea S, Winner S, Cubik S and Ariapur, as well as design control plates, pneumatic controls and exposed flushing cisterns.

Concealed cistern solutions can be particularly useful in modern bathrooms where a clean appearance and space-efficient installation are required.

Valsir Rainwater Drainage & Water Management

Modern construction increasingly needs to consider how rainwater is collected, transported and managed.

Valsir's portfolio includes Rainplus, a rainwater drainage system, along with Aquanest, a solution designed for rainwater management and infiltration.

These solutions can be considered for residential developments, commercial projects and urban applications where effective stormwater management is part of the overall building or site design.

Valsir Radiant Heating & Cooling Systems

Valsir also offers systems for radiant heating and cooling applications.

Its portfolio includes different radiant-system configurations designed for applications involving underfloor and other radiant heating and cooling installations.

Radiant systems can be incorporated into modern buildings as part of a broader heating and cooling strategy, with the final configuration depending on project design, floor construction and HVAC requirements.

Valsir Ventilation Solutions

Indoor air quality is becoming an increasingly important consideration in modern buildings.

Valsir's portfolio extends beyond traditional plumbing and drainage to include mechanical ventilation and heat-recovery ventilation solutions.

Its current range includes systems such as Ariosa HV, Ariosa V, Ariosa V Compact, Ariasilent and Brezza 60.

These solutions can be considered for residential and non-residential applications where controlled ventilation and energy-conscious building services are required.

Valsir for Residential Projects

Valsir systems can be used across a variety of residential developments, including:

Villas

Apartments

Residential towers

Luxury residences

Housing developments

Renovation projects

For residential construction, drainage, water supply, WC flushing and ventilation systems need to work together as part of the overall MEP design.

Choosing compatible products and planning the installation correctly can help simplify project coordination.

Valsir for Commercial & Hospitality Projects

Large commercial and hospitality projects have more complex plumbing and drainage requirements.

Hotels, hospitals, offices, shopping developments and other commercial buildings may require:

Large-scale drainage networks

Acoustic drainage

Water distribution

Concealed WC systems

Rainwater management

Heating and cooling systems

Ventilation solutions

Valsir's broad product portfolio allows project teams to consider different systems according to the technical requirements of each application. Valsir also showcases projects across residential, civil and industrial sectors internationally.

Valsir for Industrial & Infrastructure Projects

Industrial and infrastructure projects can have demanding drainage, water-management and mechanical-system requirements.

Valsir provides solutions covering industrial waste systems, water distribution, drainage and other building-service applications.

The selection of the appropriate system should always be based on the project's engineering specifications, operating conditions, applicable standards and installation requirements.
