Why would I suddenly lose water pressure?

Sudden complete loss points to a main shutoff valve issue, a water line break, or (if the whole street loses pressure) a city main event. Gradual pressure loss suggests a supply line restriction — scaling in galvanized pipe, a partially closed PRV, or a slow leak reducing supply pressure.

What are the signs of a broken water line?

Signs include: sudden loss of water pressure throughout the house, wet spots in the yard not explained by rain, water pooling near the meter box, a running water sound when all fixtures are off, and a spike in the water bill. A line break between the meter and the house is the homeowner's responsibility to repair.

Who is responsible for the water line from the street to the house?

The water main in the street is the city's responsibility. The service line from the meter to your house is the homeowner's responsibility — including repair and replacement costs.

How long does water line repair take?

A spot repair on an accessible section takes 2–4 hours. Full water line replacement from meter to house takes 1–2 days including excavation and restoration. Trenchless replacement (pipe bursting) can reduce that to a single day in some cases.
