i take it its unvented cylinder system to be using 10mm.
do it work ok now ?

yes its unvented and it works but slow at filling bath (as it would be)

yes change it to 15mm
shouldn't be to hard to locate where they reduced the size down to 10mm.

i quite often use 10mm for basin's and wcs where mains preasure is available but always 15mm to the bath its easy to run and great for hiding in pedestals
