I need a technician with hands-on Ao Smith experience to handle two tasks at my Ruhi Enterprise premises. First, a brand-new Ao Smith RO (reverse osmosis) water purifier has to be installed from scratch—secure mounting, proper plumbing, initial flushing, and TDS calibration included. Second, the existing Ao Smith water purifier has developed a fault and needs to be diagnosed and brought back to full working order. You’ll come equipped with the usual tools (TDS meter, PTFE tape, basic plumbing kit) and a small stock of common Ao Smith spares; anything unusual can be quoted once you identify the issue. The water heater is already functioning, so no work is required on it for now. Acceptance criteria • New RO purifier installed, flushed, leak-free, and delivering correct TDS. • Old purifier repaired and running without errors or drips. • Workspace cleaned and before/after photos shared.
