A licensed plumber in White Plains for the big older houses around the edge of the city and the commercial units in the middle of it — sewer lines, water heaters, leaks, heating and gas work, any hour including holidays. Licensed in Westchester County (#1744), insured, with the price agreed before the work starts.
White Plains is the county seat and it is two towns in one as far as plumbing goes: a dense central business district of commercial units and apartment buildings, and around it some of the oldest and largest single-family housing in the county — Gedney Farms, Fisher Hill, Prospect Park, Soundview.
That split matters, because a restaurant unit off Mamaroneck Avenue and a 1920s house on North Street fail in completely different ways and need completely different scheduling. A plumber in White Plains needs to work both, and the rest of this page is what is specific to the city rather than general.
Read off the city's own website in October 2026 and linked so you can check it. Offices and schedules change — treat the link as the source rather than this page.
The City of White Plains DPW Bureau of Water & Wastewater runs the mains, and its 24-hour emergency hotline is 914-422-1333; the office line is 914-422-1220. If water is coming up in the street, call that number first: a break in the city's main is DPW's to repair, not ours. If the main turns out to be fine, the leak is on the owner's side, and that is a job for a plumber in White Plains.
Section 3.05(a) of the city's Water Rules and Regulations, quoted in its annual water quality report, says the homeowner owns the entire service line from the water main to the water meter. So a leak in that line under the sidewalk, or under the street itself, can still be the owner's to repair; only the main is the city's. The same report sends questions about the city's lead service line inventory to the Water Bureau at (914) 422-1220.
DPW runs the city's sanitary sewer and a separate storm sewer, and checks the sanitary side for water that should not be in it: roof leaders, sump pumps, cellar drains and cross-connections between the two. So on a sewer line repair here, anything like that tied into the old house line is worth finding while the ground is open.
The city's Building Department enforces the state property maintenance code on water heaters: hot water of at least 110°F at every required sink, basin, tub, shower and laundry; an approved temperature-and-pressure relief valve with its discharge pipe; and no fuel-burning heater in a bathroom, bedroom or other room normally kept closed unless it gets enough combustion air. A replacement is the moment to put all three right, not just swap the tank.
The city flushes its mains once a year, neighborhood by neighborhood, between midnight and 4am — September covers Battle Hill, Church Street and North Broadway; October Fisher Hill, Westminster, Woodcrest and the central business district; November Prospect Park, Highland and Carhart; April and May the Soundview, Old Mamaroneck Road, Gedney Farms, Colonial, Havilands, North Street, Saxon Wood and Rosedale areas, among others. Discolored water in those weeks is usually that, not your plumbing.
Run the cold water until it clears before you run any hot. The city's own advice is blunt about this: running hot first pulls the discolored water into your tank, and then you have to run the hot until it clears as well. That is a nuisance, not a repair, and it does not need a plumber.
White Plains does not allow plumbing to be covered or concealed until its Building Department has inspected and accepted it, and the contractor, or someone responsible for them, has to be at each mandatory inspection. Any plumber in White Plains plans around that: on a bathroom or a repipe in one of the big older houses, the inspection sits between the pipe going in and the wall closing, so the tile installer is booked after it, not before.
The city's checklist for a boiler or heating device includes the Building Short Form filed as a boiler permit, drawings of the piping, a plumbing permit by a licensed plumber for gas-fired appliances, heaters and water-supplied equipment, and a flue and chimney cleaning certificate before the new boiler is first started. The Certificate of Compliance comes after the inspections, so a planned replacement is better started before the first cold week than during it.
Restaurants, salons and offices where a blockage closes the unit. Jetting and camera work, scheduled around business hours rather than through them.
Three bathrooms stacked over fifty years of alterations, and supply runs that were never meant to feed all of them at once.
Both the straight replacement, brought up to the city-enforced standards at the same time, and the cases where a tankless genuinely does not suit the gas supply, which we will say before you buy one.
From September 15 to May 31 the city expects a landlord who supplies heat to keep habitable rooms at 68°F or more, so a dead boiler in a White Plains rental is urgent from the first day. Gas boiler, radiator and steam work. We do not do air conditioning, and we will say so rather than take the job.
Where the line you need is behind someone else's unit, and the building manager has to be part of the conversation.
Older houses here can still have clay or cast iron sewer lines, often long runs out to the street under mature trees, where roots find the joints. The camera goes in first to show whether the problem is in the building's own line or in the city's wastewater sewer main, which DPW operates: we repair the first, and for the second we point you to the city. Anything draining rainwater into the sanitary line gets found while the ground is open.
All twenty-five services run in White Plains. These are the six the phone rings for most.

Need a plumber in White Plains out of hours? If the water is coming up in the street, the city's hotline at 914-422-1333 is the first call, because a break in the main is theirs.

Still not sure? Phone us — asking costs nothing.
It depends where the break is, and the city's website does not draw that line for a given property, so ask DPW at 914-422-1220 about your address before any digging is priced. What we can show you is where the problem is: our sewer camera goes in first, and you see what it found before a repair is priced. If the repair has to open the sidewalk or the street, that is a street opening or sidewalk permit, through the DPW Code Enforcement Office at 914-422-1208.
The city first if water is coming up in the street: the DPW Bureau of Water & Wastewater's 24-hour hotline is 914-422-1333, because a break in the main is theirs. If DPW finds the main intact, the leak is on the service line, which the homeowner owns from the main to the meter, and that is a plumber's job. A plumber straight away if it is inside, such as a burst pipe, a backed-up sewer line or a water heater leaking onto the floor: close the main valve and call (914) 233-3000; the phone is answered any hour, holidays included. If the problem is brown water, check the flushing schedule above first.
With the meter: close every faucet and watch it. If it still moves, water is going somewhere. White Plains bills twice a year and says on its own site that leaking pipes are not the city's responsibility; its own examples are a toilet that runs continuously, a dripping faucet and an outdoor spigot. Finding that kind of leak is leak detection.
Yes. Plumbing licensing in White Plains is Westchester County's, and the county license supersedes any city licensing. The city's own permit checklist for boilers and heating devices calls for a plumbing permit by a licensed plumber on gas-fired appliances, heaters and water-supplied equipment. KBD holds Westchester County license #1744.
