Whether you are a homeowner tackling a bathroom renovation, a gardener extending an irrigation line, or a tradesperson completing a drainage layout, the right PVC plain reducing bush makes the transition clean, secure, and code-friendly.\u003c\/p\u003e\n    \u003cp\u003eThese PVC plain reducing bushes are manufactured from rigid uPVC (unplasticised polyvinyl chloride) and feature a plain socket-to-socket design that accepts solvent-weld cement for a permanent, watertight bond. Available in three colour options — White, Blue, and Gray — to match your existing pipework or colour-code your system. The size range spans from 20×16 mm (approximately ¾\" × ⅝\") up to 90×75 mm (approximately 3½\" × 3\"), covering the most common domestic and light-commercial pipe diameters.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include cold-water supply line reductions, PVC irrigation manifold step-downs, rainwater downpipe diameter changes, and waste-pipe branch connections. Long-tail use cases such as \"PVC reducing bush for irrigation pipe\", \"solvent weld reducing socket fitting\", and \"uPVC pipe reducer for drainage\" are all served by this versatile fitting.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for Schedule 40 \/ Class D uPVC pipe systems.
