Hi Folks Please find image 1 below of a vertical soil pipe (aka stack), a rainwater downpipe, 2 boss connectors and their connecting waste pipes. The issue is that boss connector 1's connection to the stack is leaking and as you may be able to appreciate access to this fitting is limited. It was quite easy to remove a section of the rainwater pipe to gain better access to that side of the boss connector and apply a polymer sealant (OB1) - see 2nd detail image of waste pipe to boss connector 1 . The problem is gaining access to the other side of the boss connector. The plan being to remove 2 or more external bricks to get better access. The following is the technique I intend to use to do this. Source: https://www.thespruce.com/remove-a-brick-by-hand-1821083 Drill a series of holes in mortar about its width – you should know when have broken through the mortar Strike along mortar with a chisel to crack the joints Remove brick Remove remaining mortar The question is does this seem OK to you? Do you have any tips or concerns? Note can't or risky to simply cut out boss connector 1 and replace. Might be possible I realise with a specialist rubber connector connecting to socket of fitting for WC but risky and I am not sure I have easy access to inside side of waste pipe connecting to this boss connector - will at least have to take out WC and break into section of tiled floor!
