Saniflo 32mm outlet pipe to Cast Iron Stack

[SkipFeeney]

Hi all,

I need to connect a saniflo 32mm waste outlet to a cast iron soil stack. I know its not recommended to use a standard plastic boss as the Iron stack has a different diameter. I am just wondering if one of these could be used instead:

You should be able to use the McAlpine one...if you've got something to cut the stack with

I was going to go very slowly with one of these:

Good idea / bad idea?

Yeah that should do it, I'd buy yourself some cutting oil as well though

Though exceptional quality, I don't think the McAlpine Boss Connector will have a big enough internal flange or thread for cast iron pipe.

Perhaps one of these, a bit cheap and nasty I know!

Alternatively, use a Timesaver one.

Definately use the timesaver one. Anything else will leak. They're not cheap but they will last forever if installed correctly. Use a 64mm Holesaw for cutting the SVP. Will probably take an hour or so to cut using a good quality high speed drill. And use plenty of cutting oil or WD40.
