Problem extending soil pipe to reach toilet outlet

Please can anyone give me some pointers on this?

Busy fitting a new toilet, and the soil pipe comes out of the floor and has a big thick concrete collar around it .. which I don’t want to have to remove for fear of damage to the soil pipe altogether.

I removed the old fashioned toilet and fitting a back to wall and boxing in the cistern.

I’m reusing the old 90 degree connector because it just fits the soil pipe better and deeper than any new one I’ve tried, and the part meeting the toilet is the same length as any others. But, it isn’t long enough to reach the outlet pipe on the new toilet, which sits further forward than the old toilet. Can’t move the toilet any further back due to the concrete collar. I bought this particular toilet as it was the one that would fit further back than any others.

I bought two different brands/sizes of flexible connectors, but they don’t work as the natural maximum bend on both of them end up much higher than the toilet outlet.

Went to City Plumbing with my problem, and they advised that I use a straight rigid WC connector WC CON1 between the 90 degree connector and the toilet outlet.

Tried this, but it leaks when flushing .. not immediately .. but a small container catches water shortly afterwards. I’m suspecting that the water is sitting inside the straight connector, and then leaking. I’m also worried that “stuff!” won’t flush away using this method.

Also, the short straight connector has a thin plastic ring (with a break in it) inside where the black rubber seal is, I’ve just removed that .. and not sure of its purpose.

Can anyone advise if there is another way to tackle this problem?
Thanks so much.

Hi pitstop101.
Suggest you try a swan-neck connector - I think there are two lengths available. You may have to be creative with the end that fits in the floor.
