Review source, storage, cleaning, sampling, temperature, stagnation, complaints and corrective work.
Water quality depends on the whole building system
Map the supply source, tanks, pumps, treatment and the route to the unit. Request tank-cleaning schedules, laboratory reports, sampling locations, complaint logs and corrective work. Check low-use branches, dead legs and prolonged vacancy with a qualified building-services professional.
Do not infer potable quality from clarity or a single tap test. Confirm who maintains each component and how residents are notified after contamination or interruption. Read the water-tank guide, plumbing checks and buyer service.
