Before you put it
on your keys.
A few practical details to help you decide.
Is PlumbShark for the trade or for DIY?
Both. Plumbers and heating engineers can keep common small-job tools on their keys. Competent DIY users can use the radiator bleed key, meter-box key and other suitable functions around the home. Gas fittings and gas testing are for appropriately qualified engineers only.
Will it fit every radiator and valve?
It is designed around common UK fittings. The bleed-key end needs enough clearance around the vent, so a dedicated slim key may suit recessed or awkwardly positioned vents better. Always check that the tool fits securely before applying force.
Does it replace a full toolbox?
It covers the quick, common jobs that do not need a full-size tool. Keep dedicated tools for seized fittings, high torque and restricted access. PlumbShark is the handy tool you carry alongside your usual kit.
What comes with it?
One PlumbShark multi-tool with a removable carabiner and split ring for carrying it. Check the selected pack and contents on Amazon before ordering.
What is the lifetime guarantee?
*Heatlab advertises a lifetime guarantee for PlumbShark. Terms apply. Keep your proof of purchase and contact Heatlab at info@heatlab.uk with your order details and a photo if you need support. Amazon’s order and returns information is shown separately with your purchase.
