A's M & E Pte. Ltd. is a plumbing firm at 10 Admiralty St in Sembawang, Singapore, holding a 5.0 rating on Google and a listing in the Building and Construction Authority's directory of registered contractors. Plumbing here has rules worth knowing: work on water service pipes and fittings must be carried out by a PUB-licensed plumber, so it pays to ask for the licence number before any job starts. A good visit usually means tracing a leak to its source rather than painting over the stain, and covers choked floor traps, worn valves and water heater faults. Regulars know where their flat's stopcock sits and shut the water off the moment a pipe lets go, and they get quotes in writing before work begins. For homes and shops around Sembawang and the northern estates, this highly rated local plumber is a useful number to have on hand.
