Soil Pipe to cast iron fitting

[Wayne_694]

Hi guys, can you help what is the correct fitting to use, I'm after a bend 92.5 or 90 deg to suit 110mm waste pipe one end and cast iron drain the other, the cast iron side is 90mm can't find where to buy it. I have attached photos of what was in place.

Thanks

A MAC-EXTB, https://mcalpineplumbing.com/wc-connectors/macfit/mac-extac-straight-extension-macfit pushed into the cast iron and cut to legnth. Then use a normal bent pan connector such as a MAC-8, https://mcalpineplumbing.com/wc-connectors/macfit/mac-8c-90deg-bend-macfit-wc-connector

so the MAC-8 pushes inside the MAC-EXTB ?

Yes. Any bent pan connector would do, with fins, doesn't have to be the MAC-8.

Why would I need the MAC-EXTB wouldn't the MAC-8 just go straight into the cast iron drain?

also when flushing the toilet would a 90 deg bend in the drain be alright wouldn't a 92.5 deg bend be better?

thanks for your help.

No, you said the cast iron measures 90mm (old 3½"). The MAC-EXTB has a 90mm end for this situation, normal pan connectors are 110mm.

Not really, very little difference.
