Pipelines

Any pipe that is for the exclusive use of the lot, then if it breaks:
• Within the lot – Owners responsibility
• Outside the lot or in a wall, floor or ceiling that abuts to either common property or another lot – Owners Corporations responsibility.

The word breaks could be replaced by is defective and the outcome is still the same as to who is responsible. Although your pipe is not broken a leak does not change who is responsible.

Is the problem only in your water or do other units have the same issue?
Your water should not have a stain and if it is leaking then that would generally not cause a stain. If your water is stained then it sounds like some sort of contaminant is getting into the water; not water escaping.

Perhaps you should collect a bottle of the “stained” water for testing as this will help identify the contaminant and give an idea of possible sources for the “stain”. This should help find the problem, and a solution.

You need to determine if it is you or your owners corporation who is responsible, see that the responsible party takes action and ensure a competent professional finds the source of your problem and then solves your problem.
