This 32mm x 21.5mm PVC Aquaflow Reducer is a critical component for adapting and transitioning both internal and external overflow and waste systems. Specifically designed to provide a reliable, secure reduction connection in domestic and commercial plumbing, it is used to efficiently route excess water away from boilers, unvented cylinders, and large storage tanks into standard overflow lines. Furthermore, you can easily install this reducer using solvent cement, creating a permanent, leak-free chemical weld without the need for specialist mechanical tools.
Ideally matched with Aquaflow plumbing systems, this fitting allows you to seamlessly step down from a 32mm pipe to a 21.5mm overflow pipe in compact spaces. Additionally, its weather-resistant properties make it perfectly suited for handling tough outdoor applications without degrading. The reducer features a durable, lightweight PVC construction and incorporates a plain black design for a clean, unobtrusive finish that blends seamlessly into any installation environment.
Key Features & Benefits
-
Permanent Solvent Weld Joint: The design utilizes solvent cement to chemically fuse the fitting to compatible 40mm and 21.5mm pipes. Consequently, you achieve a rock-solid, permanent, and completely leak-free joint that easily withstands continuous drainage and environmental pressure.
-
Seamless System Transition: This fitting provides a neat, secure way to reduce pipe sizes without restricting necessary flow, making it ideal for connecting larger appliance waste outlets directly to standard domestic overflow setups.
-
Weather Resistant: The tough black PVC material acts as a resilient barrier against the elements. In particular, it offers excellent UV protection and withstands exposure to outdoor conditions and fluctuating temperatures without fading or becoming brittle.
-
Lightweight & Easy Handling: Its lightweight profile allows for effortless dry-fitting and alignment, making it easy to position between different pipe networks in tight lofts, boiler cupboards, or outdoor walls before applying your solvent cement.
