My neighbour in my old taman ran it from after meter and filter up the roof in the front, head straight to back as it branches to tangki. They didn't want to hack the marble flooring.

At the back, they extended and repipe to laundry and finally kitchen. The old plumbing that runs from under the floor from the front was disconnected.

This was possible as they were extending the back kitchen.

I experienced the same 2 years after pressuring with water pump in my old DSH. It caused the front garden pillar tap which was cut off and sealed to burst. Plumber who grew up near my taman related how this is designed as mandated by Syabas. This pipe branches off from the master bath somewhere. Thus my cold pipes in the master bath was exposed. 3/4" down pipe until 6" off the floor and branched horizontally using 1/2".
