Filling Loop??

Hi, we have a Potterton Suprima 30 (4160775) and have been asked by our decorators to remove a radiator whilst papering, They say there should be a filling loop, can somebody please tell me what this is and where i can find. Help !!!!

You probably don't have one. If you have 2 tanks in the loft, no pressure guage and no round blob like pressure vessel about the size of a football, you certainly don't.

Either way, all you need do is turn thr rad off at its valves, open a union between rad and valve to drain the rad, and remove it. The valves should hold the water back. You can by screw-on caps if they weep.
