Thanks for your reply. The cracked pipe under this units bathtub actually sits above the concrete slab, not under it. Can you please confirm who is responsible in this case. Thanks,
If the pipe is above the slab, chances are it is the owners responsibility. But you need to check your by-laws and your original strata schemes management statement to confirm that this is the case because there was a time when many schemes made bathroom fittings a common property issue to ensure repairs were done professionally before leaks could do too much damage.
