morning all just popped over from the tiling forum, since friday ive been trying to replace the syphon on my close couple toilet but it keeps leaking, ive bought a new close couple toilet kit but the one i took off is 50mm and it seems i can only get a 55mm kit? will this still do the job? plus i think i may of left a rubber washer off, should there be a washer where the metal bracket meets the bottom of the cistern? allso the donut rubber that came with the kit is far to big for the toilet pan do they come in different sizes? thanks in advance, and i dont think im going to be adding plumbing to my CV in a hurry....lol
