New Lead-Free Plumbing Rules to Protect Drinking Water Quality from May 2

New rules effective from May 2 mandate that all plumbing products in new buildings or renovations must be lead-free and resistant to dezincification to protect drinking water quality. The regulation aims to reduce health risks associated with lead exposure and has been supported by the plumbing industry, with minimal expected cost increases. Existing plumbing does not require replacement, but residents are advised to flush taps regularly to ensure water safety.
