I've just changed the syphon in my toilet cistern because I wanted one with an internal overflow so that I could get rid of the external overflow pipe. However, I am now left with a hole in the bottom of the cistern where the 22mm overflow pipe used to be.
I asked in one plumber's merchant and they sold me a blanking thing which pushes through and screws the other side, but I don't think it was the right thing. Firstly, it is a bit too small for the hole and doesn't fit snuggly, although with large washers it covers the hole. Secondly, it's only made of brittle plastic, and I think if I try and tighten it up too much it might break. I think it's really supposed to be for blocking off a hole for a handle in the front of the cistern, and is supposed to be above the water line and just cosmetic.
Another plumber's merchant I tried said he knew exactly what I meant, but that he only got them as part of a kit when buying a whole new cistern and he didn't have any spare, and he didn't know where to order them from.
What can I buy to seal this? I've asked around and searched but can't find anything. Thanks.
