Replace old Cast Iron waste pipe with uPVC

[Alex Nicolson]

Hi,

I'm looking to replace an old cast iron waste drainage pipe with a new uPVC pipe, including an access fitting, as seen in the attached photos, the pipe is rusting away from the inside. The OD of the pipe appears to be approx. 3" (75mm). It's bathroom basin, bath and shower waste only.

I would like to replace with white piping as the other soil waste pipes are white....but I'm struggling to find any, especially including the access fitting at 75mm (110mm appears to be the norm)

With regard to fitting the new uPVC pipe into the old cast iron base... what's my best option?, I have seen the rubber inserts but they all appear to be 110mm, I know you can get a rubber sleeve with jubilee type clips, but not an option I really fancy doing.

Any help appreciated....cheers

75mm cast iron soil pipe is available, or just replace the whole pipe with plastic.

I'd look at where it goes, into the ground and work back up from there. If the above ground section is in that poor a condition, chances are it'll be knackered at least on the join to the drain, if nowhere else.
