Help with toilet soil pipe

[Poshfox]

Could someone please advise what type of connectors I would need to fit into the ground level set below?
House was built in mid 60's, I want to replace the toilet with the "New" type, The outer appears to be of solid material and the inner has been "gashed" up with some sealant and appears flexible.
I haven't seen anything like this set up before so wondered if anyone could help?

You require a 90 deg pan connector, possibly the 'swan neck' version depending on how far the new pan/cistern sits from the wall.

Drain in the floor is either salt glazed stoneware or cast iron, probably salt glazed. Be very careful removing the old pan, the salt glazed is very fragile. If you crack the pipe downwards, may result in digging the floor up to replace it!

Thanks Hugh
Just one question, I have measured the diameter of the "salt glazed" pipe , it's around 7" how will a 4" pipe seal inside?
I have seen a 4" x 4" straight connector with a rubber finned seal and an "o" ring it the top part for the pan connector. Is one of these needed?

You've measured the 'collar' of the pipe. Other end of the pipe will is the 'spigot'. When laid these pipes were placed spigot into socket, the socket was then stuffed with a tarred rope, and the joint made good with sand/cement mix, hence the oversize collar. Picture here of a salt glazed pipe under a wooden floor, albeit the collar has almost completely broken away: http://www.diynot.com/forums/viewtopic.php?t=207289 , but does illustrate the internal bore of the pipe against size of the collar!

The new pan connector will be long enough to get past the collar and fit tightly inside the pipe below the floor.

Wow, Thank-you so much Hugh, I will have a go this weekend once I have worked out which one will be the best fitting.

Thanks for the photos and links too it's been a great help.

Remove the pan with care, doesnt matter if that gets broken, but you do not want to damage the drain! Worst case scenario, break the back of the pan away, leaving a broken stub of porcelain in the drain, remove this as carefully as you can. Broken porcelain can be as sharp as glass, gloves maybe a good idea.

Dont drop anything down the drain, you may not be able to get it back out and it could cause a blockage!
