I've heard from various people that the ro-man membrane is a cheap chinese short leaf copy as opposed to the genuine US long leaf membranes.  I'm not saying this is true but its what I've heard.

I'd get in touch with June at Gapswater, she knows her stuff.

Had a phone call from Neil at RO-man - seems the problem was definitely wonky inline meter.

Still going to change prefilters, though, sediment one is a 'orrible gungy brown, after just 6 weeks

Thanks everyone for your help.

Thanks RO-man for excellent after sales backup
