Cast iron soil stack help!!!

Hi guys got problem, original cast iron soil stack collar joint is split.
pipe appears not to be 4inches round but smaller 3 1/2 inch maybe??
When grinding the cast iron would the weight of the rest of the pipe come down??
and what fittings would best to use?? Thanks

if it is 3 1/2" L.C.C you can get a 3 1/2 x 4" stepped Timesaver coupling then use 100mm (4") pipe.
As far as the rest of the pipe coming down, well I normally use 2 or 3 "sky hooks" to secure the top half then cut. LOL Can't tell with out a look-see how much above & how well is it fixed????

Thanks, the fitting is sorted, rest is tomorrow! Ta mate them sky hooks seem good!!!!!!

They are a handy piece of kit an't they. good luck.

Thes fancy new metric ones aren't too bad , but the old imperial ones were the B*llocks.
You only had to shout Sky hook to the lad and he was in like a shot with them.
Made a change for him looking for a long weight.

so, what are these sky hooks you are talking about and where can i get them? They sound like a piece of kit every plumber should have

They are in the builders merchants always next to the :- long weights, glass nails, left handed screw drivers, bubbles for your spirit level, skirting ladders, .......................come on what else have I forgot ??

awesome. Thanks chris once again!!! I shall have a looksy next time I am there

Is it just me or has this guy just fallen for the apprentice tricks?? XD

A long stand is often invaluable in this trade.

fallen deep into mate. I have been looking for some bubbles for my spirit level for ages!!!!!!

Haha awsum!!
