Hi all, I need to remove the WC from the floor of my Santorin to replace it with an identical new one. My doubt is this: do the screws holding the WC have any slab or locknut under the floor, so that I could put the new ones without any problem? Or must I disassemble the toilet's floor? Thnk you for your help. Fair winds Ornella Santorin N° 122 Earendil
