How can I test if my toilet is leaking?

Question

How can I go about testing whether my toilet is leaking? Any help with this would be greatly appreciated.

The best way I find is to put a big piece of tissue under the collar of the pan at the back were the water goes out wen you flush it ,if you see any drips or it gets wet then you know it's coming from there and it's either the pan connector or it's the toilet cistern that sits on top of the pan

hi there 
how can you test if my toilet is leaking 
depending on where it is leaking 
1. stop using it, isolate it at the isolation valve at the toilet if there is one 
watch the water level in the pan if it lowers there will be a crack in the pan 
2. if that's, not the issue then try to get to the cistern on the back of the toilet and sponge all the water out until the cistern is dry, only put buckets of water down the toilet instead of flushing through the back of the pan as it could be the cistern leaking on a fitting on the back of the toilet leaking 

hope this helps

Flush it or pour a bucket of water down the pan. Or don’t use it for a few days

Put a dye in the water and hopefully you will see it leaking

Hi. A toilet can leak from three main places: 1. The feed into the cistern, 2. The flush connection between cistern and pan, and, 3. The soil (outlet at back of pan). If the feed is leaking the copper or plastic feed pipe (and often connected by a service valve) will be wet. Check that. If the toilet is leaking via the flush, the wider pipe which joins the cistern to the pan will be dripping water down onto the floor or soil pipe below it. This can leak only when you flush, or leak all the time even when the flush is not operated. The third scenario, whereby your soil pipe is leaking, is best detected by the foul-smelling water which will be settling on the floor behind the toilet. I would say this leak is distinctly recognisable and characterised by the fact that you would have poo and wee on your bathroom floor. I hope this helps.
