Connecting New Sink on to Cast Iron Waste Trap
Posted: Mon Apr 27, 2020 12:25 pm
Afternoon. I'd like to fit a new sink to an old cast iron waste trap in an outside utility room.
Unfortunately, it's not possible to replace the trap, the connector has been cemented quite deeply into the wall and the waste pipe exits the exterior wall at about 40 feet of the ground.
The trap is currently covered in old plaster, but should clean up ok. There are two brass threaded bolts that have sheered that, I assume, held the old sink drain in place somehow. I'm going to drill these out.
It this going to be possible and does anybody have any tips or hints to make the job easier?
I think the first challenge is going to be to find a sink with the drain in the correct position. Centre of the drain is ~110mm from the wall.
