Heating problems

[boggie42]

I am having problems with rads not coming on or having airlocks which i have to constantly bleed out.
Each one of my rads has a thermostat valve attached, how easy is it for someone with no plumbing experience to remove everyone of these and to take the rads off and wash out with a hose pipe ???

many thanks in advance..

Easy. Drain the system at all available points. Undo radiator nuts, remove radiators and invert them. Block up ends and take out for flushing.

Mind you, putting them back and making sure they don't leak can be fun.

replacing the rads after flushing is not hard, just use a bit of boss white (jointing compound) around the olive and threads to make sure the olive nips tight again and seals.
