Answers to common questions regarding water pipe replacement and sanitary plumbing in Singapore.
We strongly recommend heat-fused PPR (Polypropylene) or stainless steel pipes. PPR pipes do not corrode, are leak-proof due to fused joints, and handle hot and cold water under high pressure reliably.
A complete HDB or condo water pipe repiping project (kitchen and 2 bathrooms) typically takes 1 to 2 working days.
Instant heaters heat water on-demand for a single shower point. Storage heaters hold 15 to 40 liters of pre-heated water, providing higher water pressure and hot water to multiple points (rain showers, basins) simultaneously.
