@leakydave, replaced the MA1 679 actuator on 22mm pipe and now all is well. Many thanks indeed.

It's an MA1 for sure, it's looks very similar to the shape and size of the Drayton MA1. I'm guessing that Drayton merged with iFlo at some point. Because of where it's installed in the loft floor this is the best shot I could get..

thanks once again for your kind advice, Picasso. If we locate it, i'll come back to you...

thanks Picasso for pointing out it's the motorised valve at fault - we'll look for that until we find it! I note that screwfix also has quite a few images for us to look for. http://www.screwfix.com/c/heating-plumbing/motorised-valves/cat831028 An engineer once advised me to hit it firmly...

thanks Picasso, i checked and it appears there are no such valves visible in our airing cupboard, where all the other pipework is visible. There are gates (red wheels on top), but no valves... I do have a Duraspeed shower pump in there
