Homeowners, contractors, and facility maintenance teams working with UPVC water supply systems need a flange fitting that locks pipes firmly to walls or floors without corroding, cracking, or loosening over time. This UPVC water supply pipe floor flange delivers exactly that — a rigid, chemical-resistant mounting base engineered for grey PVC pipe systems.\u003c\/p\u003e\n    \u003cp\u003eEach flange is injection-molded from rigid UPVC (unplasticized polyvinyl chloride), offering excellent dimensional stability and resistance to chlorinated water, mild acids, and common cleaning agents. The spigot socket accepts standard metric pipe with interior diameters ranging from 20mm (~¾ in) to 110mm (~4⅓ in), covering the full range of residential and light commercial water supply pipe sizes. The flat mounting plate features pre-drilled bolt holes for direct fastening to concrete, timber, or masonry substrates.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include anchoring UPVC cold water supply risers to concrete floors in apartment buildings, securing irrigation mainlines to garden walls, stabilizing exposed pipe runs in utility rooms or pump houses, and providing a neat termination point for grey PVC drainage stubs in renovation projects.\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    Compatible with standard metric UPVC water supply pipe (grey) — interior diameters 20mm, 25mm, 32mm, 40mm, 50mm, 63mm, 75mm, 90mm, and 110mm.
