5" to 4" Waste Reducer?

[Seaweed]

Hi,
Does anyone please know if there is a 5" to 4" reducer? The old toilet in this first floor connects to a 5" internal plastic stack. It was leaking as a standard pan connector and a few tubs of plumbers mait were used.

It needs to sit inside the existing 5" Elbow as I'm restricted by depth to sit the pan where it was. Hoping there's a solution. I've been to a few merchants and a drainage specialist in Avonmouth, no joy...

Cheers, Seaweed...

A picture taken from above and further out showing all of connection would be useful.

That's an older type W.C pan socket.
Cut the 5" piece off, back to the 4" pipe and use a modern pan connector, assuming there's enough depth inside the 4" on the left for the seal to sit.

Alternately you need a seal similar to this

Thanks Snowhead, had assumed it was a 5" stack... Cheers for the assist...
