So, I have a broken pipe exactly on the L join on the wall. It's a huge crack but no big gap, just a curved crack along the pipe.
At first I thought of replacing the pipe, but it means that I have to take out the tiles and probably destroying the wall which must cost me a lot.
I've covered the crack using Marine/Plastic Epoxy Putty and it works kind of well, except that the wall part is still blasting out water everywhere when I turn the water supply back on. I tried reapplying more epoxy on the leaking area, but it doesn't seem to stick on the ceramic tiles.
So, what are my options now?
