Having replaced my toilet pan with a new one that someone gave me on Freecycle and reused the rubber seal I had on the cistern ,now when I flush the cistern there is a little water comes from the seal area below the cistern and drips on to the floor . I had also ordered a replacement inlet valve and also a replacement cistern coupling kit .The replacement pan had some silicone around it's inlet so I have removed that but was wondering if the silicone is necessary to ensure a complete seal. Can anyone offer an opinion .?
