CAST IRON TOILET WASTE COLLAR DOES NOT FIT THROUGH BACK TO WALL TOILET

[davphi338]

HI,

Renovating my daugters bathroom and she has purchased this back to wall toilet from wickes.

The issue I have is that the collar on the cast iron soil pipe does not fit through the opening on the back of toilet. I can lift the pan over the collar and lower the pan down but then theres is no space to get my hands in to make the connection between pan and waste.

Do youy think it would be possible to fit a mcalpine flexiwaste such as the item below and there would be enough flexibility in the connector to fit it into place and then lift the pan to get over the soil pipe collar?

Or is it better to bite the bullet and try cutting of the collar with a reciprocating saw and carbide blade.

Thanks for any advice as I've never cut a cast iron soil pipe before.

Cut the cast closer to the wall and fit a flexible connector. Connect the pan then push it back into place.

Check the size of the cast for which one you need. https://www.screwfix.com/p/viva-slinky-fit-flexible-straight-wc-pan-connector-white-240-500mm/120HR

Will it clear the vent stack part?

 

[denso13]

Yes, no problem. Just need to check the available length for the connector, there are a few options.

These can also be made shorter.

Or one of these, if you don't have a sawzall (reciprocating saw) but do have an angle grinder

Hi

After cutting the collar off, the internal diameter of the cast soil stack is around 85mm rather than 90mm. I'm struggling to get the fins of the Flexi connector fully into the soil pipe. I've tried washing up liquid but still no joy. Any suggestions on how to connect into a cut cast iron soil stack with 85mm internal diameter.

Thanks

Basin of boiling water for the finned end and silicone grease on the ID of the cast and really go for it. Worst case, use a sanding wheel to flatten and polish the ID of the cast to make it easier.

Cheers will give it a go.
