Silicone when building up toilet cistern

View the thread, titled "Silicone when building up toilet cistern" which is posted in Boiler Advice Forum on UK Plumbers Forums.

It shouldn't need it, just make sure you have a new doughnut washer and everything is lined up.
 
Never usually how ever most of the doughnut styles are fading away slowly and some of the foriegn makes that custards buy on there own come with diabolical washers ,, ( the ones that bolt right through but are not bolted to cist just the one bolt under wc ) hope that makes sense, so i do with them but very rarely

had one of these the other day not impressed
 
in 4 years of been self employed there was only one time I plumbers gold ed one and that was because it was a cheep plastic cistern that was twisted tried without leak then re assembled with problem solved
 
Hi woody I usually find that the plastic cisterns seal better with me than the porcelain ones,
 
when I took it back apart after trying a couple of different doughnuts I looked at at and it looked twisted once I plumbers gold ed it it didn't leak weather I was lucky or what I don't know but it worked but as I said 99% of the time they are dry fit!
 
I agree with others, never used it around cistern fittings, every time I have seen it done it's been by fitters who are really poor/ bodgers.
