I heard that if this iron 'ring' embedded in the ceilings between upper and lower units is not removed, it may rust further and may cause leaking in future. True?
The floors of my 2 toilets were hacked and re-screeded about 3 years and 8 months ago. Now, my master toilet failed the HIP water test although my common toilet passed it. Should I let the HIP contractors hack and re-screed both my toilets' floors?
My concerns:
a) I heard from neighbours, whose homes had completed their HIP upgrading, that the workmanship was sloppy and the coordination was messy -- different workers did the same job for the same unit on different days and the flat-owner had to say the same thing ten times or so.
b) Another unit's common toilet was tested by the surveyor and found to be not leaking and not requiring hacking. After 10 days of hacking and repairing the master toilet and replacing the sanitary pipes in the common toilet, the surveyor said the common toilet was leaking and requiring hacking. The owner would have to tolerate another 10 days of so much trouble and time spent.
c) Ceiling above kitchen windows of unit below mine had water leaking very badly. Someone living in the unit told HIP personnel that the leaking started after the clothes drying racks (part of the HIP) were installed but was told by HIP personnel that this leaking was not the responsibility of HIP personnel and that he/she had to report to the town council. The unit then reported to the town council. The town council then sent 2 workers to my home to check and one of them told me that it could be the silicone not being applied properly on the wall for the clothes drying rack. About a week later, the HIP contractors sent 2 workers to apply silicone. A few days after that, the unit below mine told me the leaking had stopped. HDB's reply (which I assume was from the HIP consultant or HIP contractor) was:
"Regarding HIP contractor applying sealant to the gap between the clothes drying rack (CDR) plate and the kitchen parapet, it was not meant for preventing “the seepage to the lower floor kitchen window”. It was to just seal the gap that was due to unevenness of the existing kitchen parapet. The leak reported by the lower floor resident was not likely due to the installation of the CDR. We have verified with the lower floor resident on 28 May 2021 that the leak at the ceiling above her kitchen window has stopped."
