Flowflex Click Fix

Flowflex Click Fix is a practical way to repair a small leak, pinhole or puncture on straight copper pipe without cutting out a section and rebuilding it with couplings. For the right job, that can save time and make the repair far easier where space is tight around the pipe. This collection is aimed at localised damage on accessible copper tube, with size options for 15mm and 22mm pipe, so you can match the patch to the pipe you are repairing.

The key choice is pipe size first. Click Fix patches are designed for 15mm or 22mm copper pipe made to BS EN 1057, and the patch needs to match the pipe outside diameter exactly. If you are dealing with a small damaged spot on otherwise sound pipe, this range gives you a straightforward route to a soldered repair. If the pipe is split, misshapen, heavily corroded, pitted over a wider area or leaking at a joint, you will usually need a different repair rather than a patch.

It is worth being clear that Click Fix is a soldering repair, not a push-fit, compression or heat-free option. The water must be isolated and the pipe drained enough for soldering, then the repair area needs to be cleaned and fluxed before the patch is clicked fully into place and heated. That no-cut approach is the main benefit here. You avoid cutting out pipe and fitting replacement tube, but you still need proper preparation, safe use of heat and enough working access around the repair.

Where access is awkward, that can be the difference between a tidy local repair and a more involved pipe alteration. It often suits jobs under floors, in cupboards or near other services where inserting new tube and two couplings would be more fiddly than repairing the damaged area directly. If you need other jointing components for a different type of repair, you can also browse Plumbing Fittings.

Flowflex reports that Click Fix maintained a leak-tight seal for at least 30 minutes when tested slightly above 50 bar at 22°C. That is useful as evidence of a demanding short-duration test rather than a working-pressure rating for every installation. To choose confidently, measure the copper pipe carefully, check that the damage is local rather than widespread, and pick the 15mm or 22mm Click Fix patch that matches the pipe you have in front of you.
