How to handle?
Many old buildings are still using galvanized iron (G.I.) pipes for fresh water supply. As G.I. pipes are prone to corrosion over time, they are currently prohibited by Water Supplies Department. Maintenance works in these buildings should include the total replacement of the G.I. pipes by suitable approved materials such as copper pipes or PVC lined G.I. pipes.
