In need of some help/advice

[Stm123]

Hi all, I am looking for some help/advice on a problem (feels like a nightmare) I am having.

I recently completed on a house a few weeks back, since then I discovered a small brown patch on the ceiling which had been covered with paint... I poked a screwdriver through the ceiling and it was wet slightly. Then I took a patch out of the ceiling and it seemed the chipboard was slightly damp.

Reluctantly I removed the toilet and took some tiles up in the bathroom (only 3 years old) and the floor was really wet/rotten underneath the tiles!

What I am confused/worried about is I am yet to find the actual cause of all this. I feel it could either must be the
1. Flexi pan connector? (no bad smells though)
2. Cistern down pipe connector?
3. Could it be the shower screen? the seal was knackered which I have changed, but I am not sure.

I have checked the cistern cold feed, and the the sink pipes and they seem fine, but I am scratching my head at what has caused this amount of damage as it seems it must have been going on for years.

I have attached some images of before and after along with the pan connector etc.

Any help from anyone, or any pointers would be greatly appreciated so I can put my mind to rest!

With that type of flush cone your not going to push it In easily so chances are that’s your leak source

Thanks for your reply shaun, is there a better flush cone to buy? It seems it must be difficult to tell if it's secure once the toilet is pushed back.. I have seen some threads advised to put plumbers mait/silicone in between the fins

Toilet Flush Pipe Seal Rubber Flush Cone for 38mm or 40mm Flush Pipe | eBay

Fits perfectly over a 38mm flush pipe. Will stretch over a 40mm pipe also. Thick rubber design for a better seal.

The clear one you need to put in with your hands and there tight

Tbh is this the only toilet in the house ?

Ok no worries, I will order one of these. Some threads mention the flush pipe can be too short etc so hopefully all is good there and it's just the seal as it's all tiled in

We have another one but the house is empty until we get some problems sorted

Agree with Shaun. I much prefer the rubber flush cones to the clear plasticcy ones, and prefer the external type, when the type of pan will accept one, though that's more an item you'll find in a plumbers' merchant. Don't use Mait or silicone - I think both would do more harm than good. You could use a smear of silicone grease as an assembly aid, but you run the risk of it making the cone slippery. Toolstation has (or had last time I checked) some reasonable flush cones if you want an alternative to ebay.

As for the shower screen leaking, you'd be surprised how many people will have a shower and leave pools of water on the floor.

In your case, I would fill the cistern and keep it filled and see if there is any water leaking.
There is a lot of damage, and I would assume that there is a constant water leak.
Concealed cisterns do have their issues.

Keep the cistern full of water and see if you can see any water leaking while the wall is open and the floor up.
