Toilet connection leak Drainage and wastage systems and plumbing help, advice and answers

[John drake]

I would be grateful of some advice on a problem I have encountered with fitting my new toilet. I have replaced my toilet with a Falmouth toilet from screwfix which looks good but the problem I have it weeps at the connection to the pan,I have fitted 3 different connector and the last one being a flexible type but all have the same issue. I noticed the mid point connection hole on the stack is 200mm and the toilet outlet mid point is 190mm and all the other designs I checked were about 180mm so I am not sure if this height difference to the stack is causing a flow back to the connector and the weeping or could be just the connectors were faulty, or should I have secured the connector to the toilet with some sort of fixing adhesive.
The only other cause might be a faulty toilet,I would be grateful of some advice on this matter.

Check the porcelain on the spigot where the pan connector sits. I have seen a number of toilets where the surface is damaged which prevents a watertight seal.

Dry everything toughly and liberally coat both surfaces with clear silicone sealant. This often overcomes this problem which is far more common than it ought to be!

I installed my Lecico toilet recently and worked perfectly to begin. However after about 2 months it began to seep after flushing where pan outlet meets connector. I have used silicon to try and seal around the connection but continues to leak. Level between outlet and waste stack appears fine also. I have used several different connectors and leak contiues with all. I have thought that there may have been some movement with toilet and floor but appears not. I have seen wax rings but not used yet and wonder would it work. I may now need to call a plumber. Sorry I have no answer yet.

Many thanks for your help I will exam the toilet surface for damage to see if I can spot any surface damage which might stop a good bond.
