A clip-on water collection tub designed for plumbers and DIYers. Clips around 10mm, 15mm and 22mm pipe, holds 1.4 litres, and is flexible enough to fit into the spots where a bucket simply has no chance.
The plumb tub is a clip-on drain collection tub that fits directly around your pipe, holding up to 1.4 litres of water while you work. No more balancing an ice cream tub under a valve with your knee, or mopping up the floor after a radiator decides to drain faster than expected. It clips on, catches the water, and unclips cleanly when you’re ready to empty it. Job done.
Made from flexible material, the plumb tub is designed to squeeze into the kind of awkward spaces that would laugh at a bucket. Under floorboards, behind a boiler, in an airing cupboard that was clearly designed by someone who had never met a plumber. The elastic flanges grip the pipe securely, whether it’s running vertically or horizontally, and release without a fight when you stop the flow and pull them away.
What Makes the Plumb Tub Worth Carrying
Compatibility across the most common UK domestic pipe sizes is a genuine plus. The plumb tub fits 10mm, 12mm, 15mm and 22mm pipe, which covers the vast majority of copper and plastic domestic pipework. Whether you’re draining down a radiator, sweating off a section of copper, cutting into a feed pipe or dealing with a slow drip that’s been ignored for six months, it handles the situation without ceremony.
When the tub fills up during a drain-down job, unclipping it, emptying it and snapping it back on takes seconds. That’s actually useful when you’re mid-job and water is still moving. Keep a second one to hand and you don’t even need to stop the flow. Available in two colours, so if you’ve somehow managed to acquire a system for colour-coding your tools, this fits right in.
At 250mm x 223mm x 73mm, the plumb tub is compact enough to live in a tool bag without taking up meaningful space. It’s the sort of thing you don’t miss until you don’t have it, and then you really miss it.
Pro Tip: When draining a radiator, keep a second plumb tub clipped and ready so you can swap them out without stopping the bleed valve and letting air back into the system.
The plumb tub is used wherever water needs to be caught cleanly around a pipe without setting up a bucket rig. Draining down radiators, cutting into live feeds, replacing valves, isolating sections of pipework, dealing with dripping taps or slow leaks under floors and in tight utility spaces are all typical jobs. It's used by domestic plumbers, heating engineers, and competent DIYers tackling their own systems.
It works equally well in commercial settings where pipework runs in confined risers or service ducts. Anywhere the access is restricted and a conventional container won't fit, the flexibility of the plumb tub makes it a practical first choice rather than an afterthought.

Not suitable for: Not suitable for large-scale drain-downs where flow rates are high and volume is significant. Not a replacement for proper isolation and drain-off valves on major plant or commercial heating systems.
Clip the plumb tub around the pipe at the point where water will exit, whether that's a bleed valve, a cut, or a dripping joint. The elastic flanges grip around the pipe and hold the tub in position. Make sure the tub is seated below the water exit point so everything drains into it rather than past it.
When the tub approaches full, stop the water flow briefly, unclip the flanges and empty the tub. Re-clip and continue. The whole process takes seconds once you've done it once. On longer drain-downs, having a second tub on hand means you can keep things moving without interruption.
Identify the pipe size and confirm it is 10mm, 12mm, 15mm or 22mm before fitting
Open the elastic flanges and clip the plumb tub around the pipe below the water exit point
Check the tub is secure and correctly positioned to catch flow before opening any valves
Monitor the water level during draining and prepare a second tub if needed for continuous operation
When the tub is full or the job is complete, stop the flow, unclip the elastic flanges and remove the tub
Empty the tub and re-clip to continue if further draining is required
What pipe sizes does the plumb tub fit?
It fits 10mm, 12mm, 15mm and 22mm pipe, which covers most standard domestic copper and plastic pipework in the UK.
Can it be used on horizontal as well as vertical pipes?
Yes, the plumb tub is designed to work on both horizontal and vertical pipe runs. The elastic flanges grip the pipe regardless of orientation.
How much water does it hold?
It holds approximately 1.4 litres. For longer drain-downs it's worth having a second tub to hand so you can swap and continue without stopping the flow.
The plumb tub is constructed from a flexible, resilient plastic material that allows it to be compressed and manipulated into confined spaces without losing its shape or grip. The elastic flanges create a secure seal around the pipe diameter, sufficient to hold position under the weight of water during normal drain-down and leak management tasks. Dimensions are 250mm x 223mm x 73mm with a usable capacity of approximately 1.4 litres.
