Faithfull Basin Wrench 15mm x 22mm

About this tool

The Faithfull Basin Wrench is a specialist plumbing tool designed for accessing and tightening backnuts on taps in confined spaces behind sinks and baths. Manufactured from malleable cast iron, this basin wrench features accurately machined jaws that accommodate 15mm (1/2in) and 22mm (3/4in) fittings, making it suitable for the most common tap connections found in UK plumbing installations. The extended shaft design allows plumbers and contractors to reach into awkward areas where standard spanners and adjustable wrenches cannot operate effectively. The malleable cast iron construction provides the necessary strength and durability for professional use whilst the precision-machined jaws ensure a secure grip on backnuts without damaging chrome or brass fittings. This basin wrench is ideal for tap installation and replacement work in kitchens and bathrooms, particularly where access behind basins and baths is restricted. The tool's design makes it indispensable for any plumber or tradesperson regularly undertaking sanitary ware fitting.
