Finding a leak????

How can i find where our toilet cistern is leaking from?

A drip is forming on the bottom but from what i can see the water is not actually coming out where the drip is forming.

How do i find the source of the leak?

Cheers

its not just condensation is it

Stick some of that coloured toilet cleaner in it....and then you should see any leakage. Worked when we had a hairline crack in our last cistern

Ahhhhh clever!

This will also show if its condensation or not.

Thankyou muchly.

Bloo Blocks here we come.

food colouring then, plaque indicator?

I take it it's close-coupled? If it's not condensation my money is on it leaking from the "doughnut" - the massive rubber o-ring that seals the cistern to the pan.

Thats the current solution!
