BS EN 274 is the UK and European Standard for sanitary tapware waste fittings including traps, plugs, overflows and chains, covering both performance and dimensional requirements. The standard is widely referenced in product datasheets for bathroom and kitchen fittings sold across the UK, including most products supplied by major plumbing merchants. Practical implications for homeowners and contractors across Greater London include the confidence that a trap, basin waste or sink strainer carrying BS EN 274 marking meets recognised flow, durability and water seal requirements. The standard is published in three parts: BS EN 274-1:2002 covers requirements, BS EN 274-2 covers test methods and BS EN 274-3 covers quality control. It is regularly read in conjunction with Building Regulations Part H1 and BS EN 12056 when designing complete sanitary pipework systems.
