Heads up, my unit is at Level 18 type A (furthest unit from lift), tested water pressure today, kitchen and center bathroom is okay, but masterbedroom bath abit weak, however not sure whether the roof top pneumatic pump is on or not.
For those who not familiar, according to Syabas requirement, water supply for highest few floor of high rise building requires either
1) Roof top tank with min 3 meter high plinth
2) Pneumatic pump with different pipe network from other floors
If you check the riser, lower floor will be using ABS (blue plastic) as main dropper pipe while pneumatic pump will be using metal pipe (can't remember which material)
Meanwhile on defect rectification, all defective electrical switch has been changed, but the contractor remove my masking tape marking and stick it on my intercom with dirty finger print all around. No sign of rectification on hollow tiles and defective window yet.
PS: 1 of my access card failed to open any door (Green light but still locked), do check every single access card you have.
I have just submitted mine on 25th Jan. Mine is also type A but on the 12th floor. Im just worried how long they will take to rectify all the defects. Among other defects i also experienced some hollow tiles in the unit.
