Thanks for the replies....i'll give the garden hose theory a miss. I can understand the "take all the rads off" approach but I don't fancy my luck at getting 11 off and back on again without leaks to deal with.....unfortunately I only have one day (tomorrow) to do this....maybe I should do the best I can for now by draining and filling and look at hiring a powerflusher....I can get one of these for £50 from my local HSS, unfortunately they wanted 3 days notice and I didn't have the time.
I do already have an inline Y strainer fitted to the CH return pipe but it doesn't seem to have made any difference.....the Y points upwards, could this have been fitted the wrong way round ?
