  • Plumbing contractors face significant challenges during mandatory drainage system testing. Traditional test plugs are difficult to install and remove, prone to water spillage, and are often lost in piping systems, leading to costly retrievals and the risk of potential blockages. Existing solutions are either expensive or inefficient, posing operational and safety risks. Vinidex identified the need for a reliable, user-friendly test plug that addresses these issues while ensuring compliance with AS/NZS 3500 water-tightness testing requirements for multi-storey buildings. This innovative solution aligns with Vinidex’s “Systems Approach,” enhancing value for plumbers and merchants.

  • Based on insights from plumbers, the Vinidex IO Test Plug features an integrated finger-pull handle for safe and easy installation and removal, a keyway-slot system for perfect alignment, and a durable, reusable construction. Compatible with all Vinidex DN100 Inspection Tees, it prevents water spillage during removal, improving safety and reducing clean-up. The tool withstands internal pressures beyond AS/NZS 3500 requirements and has undergone extensive testing for durability of the precision-designed TPE seal. The open inspection cap allows for a visual indication of the plug’s presence. This solution addresses user pain points directly while promoting integration with Vinidex systems.

  • The Vinidex IO Test Plug delivers positive commercial, environmental, and societal impacts. For plumbers, it reduces installation time, improves job safety, and eliminates the cost of retrieving lost tools. Environmentally, it is made from recyclable material, and its reusable design reduces waste associated with disposable or lost plugs. For our merchants, it creates pull-through sales opportunities with Vinidex Inspection Tees. Commercially, it supports Vinidex’s position as an innovator in plumbing solutions. The IO Test Plug strengthens Vinidex’s strategic goal to become the preferred drainage system supplier in multi-residential markets, fostering customer loyalty and growth.
