The aptly named Plumb Tub is, in case you hadn’t already guessed, a tub for plumbing. It’s not the sort of product that’s going to revolutionise the plumbing world but it is the sort of cheap, durable and easy to use knick-knack that is well worth having in your arsenal of plumbing tools.
It’s just a nice little bowl of soft, rubberised plastic that can fit neatly under a radiator. At each corner is a hole that is cunning sized to accept the sort of pipework that you’ll normally come across in a domestic plumbing system, namely 10,15 and 22mm. Just ease the appropriate corner of rubberised plastic around the pipe and relax as any wayward drips and leaks are directed into the bowl.
Ok, the bowl isn’t the biggest so you might want to have a water vacuum pump nearby just in case the leak proves to be bigger than expected. It also doesn’t do 8mm pipework, or at least it’s not mentioned in the literature, which is a shame as a worrying amount of CH systems were plumbed in using 8mm pipework. That said, it's a perfectly handy pot for putting all your bits and bobs in after the job and it only costs a few quid, so why not give it a try anyway.
