The ceramic cistern for my toilet has a crack in it (sorry, it's not a great photo: the crack is from the hole that the down pipe to the toilet bowl goes into and it goes to between 10 and 11 o'clock in the photo.) Previously I've mended it with No Nonsense clear silicone applied from the outside edges of the rubber seal washer to beyond the end of the crack and it's lasted about three years, but it's now leaking again. I've now removed the old silicone as best I can and I'm going to try sealing it again.
My question is: Is there anything that would work better than silicone sealant (e.g. plumber's mait)? Thanks.
