Hi, wondered how i would install a w/c downstairs, the sink is no probs but my main problem comes with the toilet and waste/soil pipes. The floor is solid concrete and has no existing soil pipe, so i want to know how i would get around this! the toilet will be mounted on an external wall and about is directly below the upstairs toilet so the waste pipe from there runs down the same external wall.
is there anyway to install the toilet without digging out the concrete??
Any advise would be greatly appreciated.
