Water Main Repair in Manhattan

Water Main Repair in Manhattan, From the City Main to Your Meter

In Manhattan the water service from the main to the meter belongs to the building’s owner, and on most buildings it is bigger and busier than a house line. When it leaks, we find the leak first, then repair the section or relay the service in copper.

Bigger Services Under Busier Streets

Manhattan buildings usually need larger water services, and many have a separate fire service line. Older buildings and brownstones may still have lead or galvanized services.

Work under the street is planned around the DOT permit’s hours, the building’s schedule and the utilities already in the ground. We replace in copper from the main to the meter.

Signs Your Water Line Is Leaking

  • Water at the curb or sidewalk that does not dry after a few days without rain
  • Low pressure through the whole building
  • A water bill that jumped for no reason
  • A hiss under the sidewalk
  • Cloudy or rusty water
  • A leaking curb valve

Whose Line Is It, and What a DEP Notice Means

The water service from the city main to your meter belongs to the property owner, including the tap on the main and the curb valve under the sidewalk. When DEP finds a leak on it, the owner gets a 3-Day or 10-Day Notice, and the clock starts on the date printed on the paper. See DEP notices and compliance.

Repair or Relay?

A repair is usually enough when

  • There is a single leak on a copper line in otherwise good condition
  • Pressure is normal everywhere except near the leak
  • The line has not failed before

Relay the whole line when

  • The pipe is lead or galvanized: patching it leaves the rest in the ground
  • Leaks keep coming back after repairs
  • Pressure is low throughout the building, or the water runs brown
  • The building needs a larger service

Lead Service Lines

New York City stopped allowing lead service lines in 1961, so a building older than that may still have one. If yours does, we replace it in full, in copper, from the city main to the meter, with a new no-lead brass curb valve. Replacing half a lead line leaves the other half in the ground.

How a Manhattan Water Main Job Runs

  1. Locate the leak. Before anything is dug, so the excavation goes where the problem is.
  2. Permits and mark-out. We file with DEP, pull the DOT street-opening permit, and call in the utility mark-out.
  3. Open the street or sidewalk. On a busy street, the DOT permit sets our working hours, and the water shutdown is agreed with the building.
  4. Repair or relay. Type K copper and no-lead brass fittings, tapped to the city main where a new connection is needed, under the licence of Master Plumber #2389.
  5. Pressure test and inspect. Before anything is backfilled.
  6. Restore. Backfill, then the sidewalk, curb, street or yard put back.

The digging is the quick part. The permits set the calendar.

“The Lady Liberty crew came on time with lots of excavation equipment, explained their work plan to me and cautiously worked throughout the day to complete the installation of the new water pipe into my house. Hard working crew, left the street and sidewalk repaired and clean as was before.”

Nick K., Google review

“The crew worked hard and multiple holes were dug up. My water main pipe was replaced in one day with minimal damages to my driveway pavers. They cleaned up after they were done.”

Manhattan Water Main FAQs

Who is responsible for the water line to a Manhattan building?

The owner, from the tap on the city main, through the curb valve under the sidewalk, to the meter in the building. DEP maintains the main in the street.

How do I know the leak is on my side?

If DEP has sent a 3-Day or 10-Day Notice, it has found a leak on the owner's side. Without a notice, a wet patch at the curb that does not dry, low pressure and a jump in the bill all point to the service line. We locate the leak before anything is dug.

Can you help with a DEP 3-Day or 10-Day Notice?

Yes. We find the leak the notice is about, file the permits and make the repair. See NYC DEP notices and compliance for how the notices work.

My street was just repaved. Can you still open it?

Sometimes. The city treats recently resurfaced streets as protected: opening one needs DOT approval, comes with stricter restoration rules, and some work has to wait. We check a street's status before we quote, so you know before anything is scheduled.

How do you schedule work on a busy Manhattan street?

Around the DOT permit, which sets the hours and sometimes the days we can work, and around the building. You get the schedule before we start.

Do you install fire service lines too?

Yes. Fire sprinkler mains are one of our services, and on a larger building we look at both lines together.
