Thanks for the answer. All i needed to get lid off was a medium flat head screwdriver and my little finger, easy when you know how. But what a bloomin nightmare overall. Little things like this can hold a job up for ages. 2 of the 3 Roca's in my house have been iffy. Thank god for google. Prob now sorted. Good job, as i was dieing for a leak.
