Added a new radiator at the weekend, to a vented system which I had recently added new inhibitor. New rad is on top floor and I had laid on the pipework previously, so only a towel rail needed draining, and the expansion tank. Not wanting to lose the inhibitor in the expansion tank, I wanted to plug the outlet. Hunted around, and then hit on the idea of using the plug of silicone which sets in the nozzle of a silicone gun tube. Blew the plug out backwards with a compressed air can, and it worked perfectly.
Plumbing tip of the day

Genius. I'll save the next ones I come across and put them in my plumbing box for future use.
Great tip.
I have, long ago, successfully used a raw carrot for a similar purpose.
Small Dutch boy anyone?
Was the taste affected?
After some experience of trying to do pipework when young, my tip of the day is get a plumber in unless its a simple waste pipe issue... Brian
Traditionally it was a carrot on the tank outlet and a potato over the end of the vent pipe.

Many years ago I bought a set of rubber plugs for precisely this sort of job. With string attached to make them easier to remove, and less likely to get lost.
You missed out. Bending and soldering copper tube to a neat job is one of life's little pleasures.
+1 as they say.
