Cast Iron Soil Stack

Nov 17, 2004 8 Replies

What is the safest way to remove an old cast iron soil stack. Is an angle grinder suitable to cut the pipe into smaller sections?



This needs to be done as the separate w/c and existing bathroom are being converted into a shower room with w/c and a smaller family bathroom again with w/c. All the other wastes from newly installed showers, baths and basins will then connect to, via appropriate sized bosses, a new plastic soil pipe.



Thanks

Yes, a 9" grinder makes short work of cast iron stacks.

When our cast iron gas main was replaced with plastic recently, the workers broke up bits of old pipe with a sledge hammer. You could probably do the same with your soil stack.

I've done it with both a grinder and with just a normal hammer. Both easy, but I felt at least with the hammer, I didn't have such a heavy tool to hold whilst up a ladder. Getting the sodding great nails out of the wall proved a little more difficult however.

Start at the top and work your way down. Rig a rope and pulley if you're doing this job by yourself, making it a locking sort of pulley to give better control.

Once the brackets are removed from the stack, the top section of cast should be allowed to wiggle around and loosen from it spigot. When it is loose enough to lift out, then catch it on the pulley and lower it to the ground.

Once you have all the stack on the ground, then bash it all up with a big hammer (BigWallop) and put it in bags for removal from site.

Wouldn't this stuff be valuable of salvaged?

Nooooo!

CI could be used for renovations on a period property, or it makes good stove pipe.

If put to one side it may magically remove itself, or a nearby architectural salvage place or a scrappie may take it.

At the very least leave it in a neat pile at the tip and someone may find it useful.

cheers, Pete.

? 4" stove pipe?? I'd like to see you get that past a BCO.

Stick a matock behind the cast iron clip and lever it out! If any bits are left sticking out that is where a (small) angle grinder helps.
