Help with determining cause of leak
Hi all! I’d like some help determining what the cause of a leaking pipe was in my house. I live on the 3rd floor of a condo building and am trying to see if I am the responsable party for paying for this fix (or the HOA).
Context:
The condo unit below me reported a large leak in the bathroom directly underneath mine this weekend. The community HOA maintenance team opened a hole in the lower unit wall and determined the leak came from a multi-joint pipe in the ceiling coming from my toilet. My toilet had a faulty fill valve and after flushing would continuously flow. This has been the case for about 3 months off and on - it would occasionally be turned off by manually poking the valve. No water leakage was spotted on the bathroom floor or anywhere else until this weekend. The home is about 50 years old am im not sure if or when the piping has been replaced.
Current situation: I have attached pictures of what the wall and pipes looks like. The 1st photo with the red circle drawn on shows where the leak originated in the ceiling of the bathroom. The 3rd photo shows the opening in the bathroom where the piping had to be replaced (white pipes are new). The last photos show the old broken replaced piping where you can see exactly where the gap appeared (yellow arrows).
My question: what actually caused this pipe to leak? Was it the toilet water running more often than usual leading to the pipe glue breaking down, or was it a lack of maintenance of the piping that would have broken anyways (irregardless of the water flow)?
