Plumbing and drainage keys are essential hand tools used to operate, adjust, or access valves, covers, and fittings within water and drainage systems. These robust tools provide the leverage needed to engage fixtures that are recessed, rusted, or otherwise difficult to access.
Commonly used on stop taps, drain covers, and radiator valves, plumbing keys help installers and maintenance teams perform critical functions such as isolating flow, removing inspection covers, or servicing heating components.
