Laufen OV302 Dual Flush Valve Only — OV203C
The Laufen OV302 (stamped with casing mark OV203C) is the authentic replacement dual-flush outlet valve mechanism manufactured for Laufen ceramic WC suites, most notably the classic Laufen Vienna series. If your toilet is passing water continuously into the pan or failing to flush properly, this direct-replacement valve body restores positive mechanical dual-flush operation and ensures a watertight base seal.
