Extending WC waste

[Hallsy]

I'm moving my WC across by about a 1m from the soil pipe.

Will a 90 degree pan connector (with the ribbed rubber bit on end) fit straight into a length of soil pipe, or will I need a collar?

I'd try but I don't have any soilpipe here at the mo!

As long as the O.D. of the pan connector spigot is at least, say, 6mm less than the I.D. of the soil pipe, it will fit in, and and as long as the O.D. of the rubber ribs is at least 4mm more than the I.D. of the soil pipe, then it will seal adequately.

Cheers mate, I did think it looked small enough to physically go in with the rubber sealing it but wasn't 100%.
