The Holman DWV Plain Coupling is a reliable and durable plumbing fitting designed specifically for sewer and vent applications. Manufactured to meet the requirements of AS/NZS 1260, this 100mm coupling provides a secure and watertight connection between two sections of DWV (Drain, Waste, and Vent) pipe. Its simple design allows for quick and easy installation, making it a go-to solution for both professional plumbers and DIY users tackling home drainage systems.
Made from high-quality, UV-resistant PVC, the Holman DWV Coupling is engineered to withstand Australia’s harsh outdoor conditions and resist corrosion, chemicals, and soil movement. Whether you’re extending an existing pipe run, making repairs, or completing a new installation, this coupling delivers long-lasting performance and peace of mind. It ensures optimal flow of wastewater and air within the drainage system, helping to prevent blockages and maintain hygienic, odour-free conditions.
With no internal ridges or obstructions, the smooth bore of the coupling ensures efficient flow and reduces the chance of debris build-up. Its compatibility with standard 100mm DWV pipes makes it a versatile and essential component for any drainage project.
