old radiators and inserting cleaner/inhibtor

[GQuigley67]

alright lads i'd like to know what you all do when you go to a job and its all old radiators, and there is no way to put in cleaner/inhibitor.

usually I open bleed valve, attach my made up contraption tundish thingy which is an 1/2" bsp connection into the radiator via the bleed point or blank cap, and pour my cleaner/inhibitor in, but I'm wondering what you guys n gals do when its the old style radiators with the bleed points only ? how do you put the chemicals in ?

.I know you can get ones that you can insert via the filling loop, but I'm talking the bottles here.

I have my own way of doing things, but I was wondering if anyone has a better, quicker way than me

If the systems empty you could take the filling loop off and pour it in but the easiest way is to make yourself an injection pump.

Depends if the system is drained fully or not. If it is, I find the smallest rad, take it off with the valves on the rad. Turn it upside down, pour inhibitor in, close valves and refit. Then open valves once you are happy there are no leaks.

Again if it is drained down, take a valve off and pour it straight into the pipe work.

o/v system header tank or sealed system filling loop simples

if the system is empty i have a iso on a bit of copper soldered onto a copper tundish, i screw the iso thread into the thread where blanking plug sits and pour away!

for imperial threads i use an imperial conversion coupling!

Thats what i do, im talking about old radiators that dont have blank plugs.

i like your way Mike, think I will go with that one cheers!

I have a rust buster to inject into the full loop not sure they ate still available though

Ronseal decking sprayer! Only about £10 and just attach the fitting younger with inhibitor and pump it in! Easy as Murray winning Wimbledon

Rad off the wall job, pour it straight in stick it back on.

just carry a couple of these, no mess and charge the custard, and more room in the van

For newer rads, I have a compression t, 22-22-15. 2p in one 22 end, 15 straight into the top of the rad, pour the liquid in the 22 at the top.
