J.S. Plumbing Contractor Pte Ltd is a plumbing firm based at 203 Henderson Road, #09-09, Henderson Industrial Park, in Tiong Bahru, Singapore, and holds a 5.0 Google rating. In Singapore, work on the water supply must be done by a plumber licensed by PUB, the national water agency, so it is worth asking for the licence number before a job begins. A good visit starts with diagnosis rather than guesswork: tracing a leak to its source, testing water pressure, then quoting for a proper fix instead of patching symptoms. Older neighbourhoods like Tiong Bahru, with its 1930s conservation flats, see plenty of ageing pipes and weak pressure, so experience with older buildings counts for a lot. Regulars know the plumber worth keeping is the one who explains the cause, not just the cure. From its unit in Henderson Industrial Park, J.S. Plumbing Contractor sits close to the residential streets of Tiong Bahru.
