New toilet leaks when flushed

[Slicecbr]

Hi,
I need more experienced eyes to help me please!
I've replaced my toilet with a new one.
It doesn't leak unless it's flushed and a little pool of water forms along in the left hand side of the toilet.
As it's a spare bathroom I've not looked into it more until today.
So I flushed it, waiting until a drip appeared and then took it, please see pictures. You can see like drips going down along the left hand side of the toilet. I couldnt find any evidence of water dripping from any of the connections from the top.
Any help!?

Sorry I can't see the drips.

I prefer McAlpine pan connectors (if yours is dripping from there??).
If it's not from the pan connector, is the cistern water tight to the toilet pan.

On cheap toilets I bin the supplied fittings and use this, as I find the foam gaskets supplied are junk

Close coupling kit

Many thanks, yeah it was a cheapish toilet, so may just do that. I've added a photo to show where the water drips are that I could see, just beyond the white casting mark, as I said I couldn't seem to feel any water coming from above

Are you saying that water drips from the internal side wall of the pan ,or is it the round ceramic pan outlet ?

 

[Slicecbr]

Looks like from the internal side wall of the pan. I can't see how the water from the round ceramic pan outlet could push the water that far to the front of the toilet

Could be a hairline crack? Do you have any food colouring?

 

[Slicecbr]

Yeah good point, I'll add some red and see how it looks

If that's correct then there is a fault within the WC pan itself. Water shouldn't be able to escape internally from the waterways within the rim.

I had the same issue when I installed the downstairs toilet. For around a year after I installed it, water would pool underneath the left hand side of the cistern. I put the leak down to the seals between the cistern and the pan (where gaskets and wing nuts are used). I don't think I can tighten it any more by hand, but thankfully it appears to have stopped -- I assume the small gap has now simply scaled up.

The cistern blocks my wife is obsessed with had left a trail of blue-coloured water down the back of the pan. Food colouring as suggested would work great.

Thinking aloud...

If you use a bucket full of water to flush it you will be able see if it is the soil pipe connector or not.

If no leak, it is then either the close couple or a fault in the pan.

Many thanks for all the replies. Yeah, I'm going to put some red food colour in and then hopefully trace the leak. I did take the toilet out and used water to flush it when on the grass but couldn't see anything obvious, but only did it.once as I had the water supply turned off. Will try again in the next couple days and will post an update.
