The firm says it runs 24-hour emergency calls for HDB flats and aims for a 30-minute response across the island. Its work includes leak detection for concealed pipes, clearing chokes in sinks, basins and toilets, replacing flush mechanisms and installing storage and instant heaters, with brands listed as Joven, Rheem, Ariston and 707. It also re-pipes old HDB flats, fits rubbish chutes and water booster pumps, and installs mixers and taps.
