Plumbers asked for more expansion allowance! Holman Plumbing delivered.
For years, plumbers working on multi-storey and commercial DWV stacks have told us the same thing: the DWV PVC expansion fittings available in the Australian market weren’t cutting it. Not enough travel. A separate expansion coupling and inspection opening on every stack. More fittings, more joints, more time on the tools.
We took that feedback seriously.
Designed with plumbers in mind and built right here in Australia – introducing the new Holman 100mm DWV Expansion range. A dual-function fitting that combines an expansion joint and inspection opening into one product. It provides a controlled expansion joint to accommodate thermal movement while also offering a convenient access point for inspection, cleaning and maintenance. This combination reduces system stress, improves reliability and simplifies ongoing servicing.
With the maximum allowance in market being 55mm, we pushed further because that extra range matters, on long vertical stacks and exposed horizontal runs where thermal movement is most extreme, 65mm means better absorption, less stress on joints and fewer call-backs. Less fittings, less time, less hassle.
No more cutting. No more patching. No more drama. The built-in removable inspection cap means camera inspections, blockage clearing and routine maintenance can all be done without cutting into the pipe. One fitting, two functions, less hassle.
Always compliant. Always trusted. The Holman 100mm DWV Expansion range is WaterMark approved to AS/NZS 1260 (Lic. 74772) and proudly made right here in Australia.
Holman Plumbing is part of Reliance Worldwide Corporation, a global leader in water management solutions. Our mission is simple: Plumbing Matters. We Make It Better.
