The White UPVC Overflow Solvent Reducer (21.5mm) is used where an overflow pipe system needs to transition from a larger diameter pipe down to the standard 21.5mm overflow size. It provides a clean and reliable reduction point while maintaining controlled water discharge.
Manufactured from rigid UPVC, the reducer is suitable for solvent-weld installation, ensuring a strong and permanent joint once fitted. It is commonly used in domestic overflow wastewater systems connected to toilet cisterns, cold-water storage tanks, and heating appliances where pipe sizes differ.
Supplied in two size options, the reducer allows flexibility during installation while keeping the final overflow outlet consistent at 21.5mm. Finished in white, it matches other overflow pipes and fittings for a tidy, uniform appearance. This fitting forms part of the Overflow Wastewater System 21.5mm, within the wider Wastewater category.
Available Sizes
- 23mm to 21.5mm
