Hi everyone in the US - posting from Glasgow, Scotland.
I’m remodelling my bathroom in a three storey 130 year old tenement block (apartment) and would like to remove this old cast iron pipe that used to supply cold water from a tank in the loft. The tank was removed years ago when the flat above me was converted into a duplex. The pipe needs removed as it is blocking a bath from being positioned where I want.
I’m on the 2nd floor (we call it the 1st floor). There's a flat above me and one below.
The circumference of this pipe is 9", using Pythagoras I get 2.86479" for it's diameter which seems to be 2 and 7/8" OD. Is that a 2.5" pipe then?
My plan is to use two riser clamps to hold the pipe above and below me and then cut out this entire section. I used an inspection camera to look into the joist space above me and there's no obvious hub or joint under which I could position the riser clamp, so Ill be relying on the friction between the clamp and the pipe alone.
I wanted to know whether a friction hold by one of these clamps would be sufficient to hold the 3m section above me (including it's own staples and clamps etc. I would be securely sitting the riser clamp on a strut/dwang between the ceiling joists above.
When ordering the riser clamps how should I be sizing these?
Many thanks for any advice & recommendations.
