Choke clearing Jurong West
Choke clearing in Jurong West means locating the blockage and clearing the line properly rather than pushing it further along. A choke that returns within weeks was never cleared.
Why this is different here
HDB began planning the Jurong West new town in 1984, and by 2018 the estate held 74,301 HDB flats. Flats of that generation are on their original riser and branch pipework unless it has since been replaced, so the recurring jobs here are corrosion pinholes, seized stop valves and chokes at old joints rather than fitting failures.
What actually happens
- Stop valves of that age often seize, so isolating before work is its own step.
- Chokes tend to recur at old joints, which is why a clear alone frequently is not the fix.
- Pinhole leaks show as staining before they show as water.
