Hi all, Just bought a resale 2 room flat and the main sewage/water pipe ( linking top and bottom floor) is badly rusty. The area is scheduled for HIP program but we do not know when it will start for our block. I would prefer to have it replace together with the renovation. The ID, intro by the property agent says he is not allow to replace it. But I believed it can be done if apply for permit from HDB by the ID? I was thinking of engaging another contractor just to do the piping before the main renovation start. The ID is quite a friendly guy and explain alot of those renovation stuff so I might want him to do the renovation. Anyone can recommend a contractor that is ok with just doing the piping? I might want to talk to the ID again about the piping when we meet again to discuss the quotation, but for now I shall start looking for an alternative in case he still do not want to do the piping.
