Standard uPVC 1¼ Inch Waste Pipe, 32mm, White

1¼ Inch Waste Pipe

The Standard uPVC Waste Pipe serves as the primary conduit for secondary drainage systems in residential and commercial plumbing installations. Manufactured from high-grade unplasticized polyvinyl chloride, this 32mm nominal diameter piping ensures efficient transport of greywater from internal fixtures to the main soil stack. It meets standard building regulations for non-pressure waste discharge applications.

Built for the Job

Plumbers and site contractors specify this piping for internal waste management where space and flow efficiency are paramount. The 32mm sizing is the industry standard for connecting washbasins, bidets, and urinals to the wider drainage network. Its lightweight construction allows for rapid overhead installation in ceiling voids or behind partition walls without requiring heavy-duty structural supports. The material resists the corrosive effects of household detergents, bleach, and hot water discharge typically found in bathroom environments. This piping remains stable under varying thermal conditions, though installers should account for standard expansion rates during long horizontal runs.

• Connection of bathroom washbasin traps to secondary branch lines.

• Installation of condensate drainage for air conditioning units and high-efficiency boilers.

• Routing greywater from bidets or small urinals in commercial washrooms.

Product Highlights

Hydraulic Efficiency

The ultra-smooth internal bore minimizes friction loss and prevents the accumulation of biofilm or solid debris that causes blockages.

Material Durability

• High chemical resistance against common domestic cleaning agents.
• Impact-resistant uPVC wall thickness designed for job-site durability.

Technical Specifications

What’s Included

• 1 x 3-Meter Length 1¼ Inch uPVC Pipe (Standard cut)

On-Site & Workshop Notes

• Ensure all cuts are square and deburred before applying solvent cement to prevent leak paths.

• Maintain a minimum gradient of 1:40 (25mm per meter) to ensure adequate self-cleansing velocity.

• Use compatible pipe clips every 0.5 meters for horizontal runs to prevent sagging under hot water loads.

• Store this material on flat surfaces away from direct sunlight to avoid UV degradation and bowing.
