staind,

If you don't see any leak after the meter, tapos nakasara ang mga gripo at umiikot ang metro, definitely there's a leak somewhere in your water line starting right after the meter going into your house, ikot ng ikot ang meter mo nyan. If this is the case, walang magagawa ang Manila Water kasi wala naman problem before the meter or on the meter itself.

ang kailangan mo eh tubero or, maglalatag kayo ng panibagong water line/pipe from the meter into the house

Ganyan naging problema ng hipag ko, yun nag latag sila ng bagong linya, umayos naman.
