Damp patch next to WC pan, where is it coming from?

[dontknowitall]

Is there a heating pipe underneath or plumbed underfloor heating - or perhaps coming in from outside?

Thanks, we've thought of that, we keep the room well ventilated and we thought the damp patch would dry out while we were on holiday for two weeks, but it didn't. So I think I have a hairline crack in the pan as suggested here. It does seem really odd and from the inside of the pan there is no sign what so ever of a crack, hair line or otherwise. It's now a case of having ruled all else out so it must be a (small) leak from a small crack. I think.......

Thanks, I've thought of that too. There are no pipes under that part of the floor, the ceiling below is bone dry and the outside wall is very sheltered and completely dry. Cheers.

Is it the only pan in the house or do you have another. Take the pan out put some water in it on a dry piece of floor and see if it gets wet underneath if it does its the pan if not could be something else.

Yes no point just changing pan if that's not the problem

Good points, we do have another one we can use. I am not sure Mrs Bloggs will let me do that (she's a bit fussy like that) but it is worth thinking about for sure. Thanks.

Just persuade her that some very informative people have advised you to do it and if you dont do it youll make her pay for the new pan

Hello Fred and welcome had a similar problem once took pan out dried thoroughly placed on some cardboard put some water in and checked every 10 mins or so nothing then my pal turned up and sat on it jokingly and after a few moments we noticed a damp patch on the cardboard put some drain dye in and he sat on it again we emptied it and turned the pan upside down and found a hairline crack showed up by the dye good luck with your problem regards turnpin

Try using some tissue paper to see if there's any wetness where the pan connects to the pan connector.
