Downtown Brooklyn has changed more than almost any part of the borough. Around Borough Hall, MetroTech, the Fulton Street Mall and Albee Square, older office buildings, courthouses and former department stores now stand next to dozens of new residential towers. Nearly every subway line in Brooklyn passes through the area, with major stations at Jay Street-MetroTech, DeKalb Avenue and Borough Hall.

Plumbing here is mostly building plumbing: domestic water pumps and risers in tall buildings, backflow preventers on the water services, commercial kitchens in food halls and restaurants, and gas piping that falls under Local Law 152. The older low-rise buildings scattered among the towers have their own problems, like aging cast iron and steam boilers. We work with building managers, retail tenants and condo boards.

Common plumbing issues in Downtown Brooklyn
Leaks that cross floors
In a tower, a leak in one unit's supply line, a failing shower valve or a cracked drain fitting shows up in the ceiling of the unit below, sometimes several floors down. We trace it back through the stack of units, isolate the line and repair it with as little demolition as possible, coordinating access with management.
Pressure, pumps and PRVs
Tall buildings use pumps to get water to the upper floors and pressure reducing valves to keep it from being too high on the lower ones. When a PRV fails, lower floors can see banging pipes and dripping fixtures. When a pump fails, upper floors lose pressure. We diagnose and repair both sides of the system.
Food halls and restaurant kitchens
Street-level and food hall kitchens produce a lot of grease, and the lines that carry it often run long distances through a building before reaching the sewer. Regular jetting keeps them flowing. We use our own van-mounted jetter and can schedule cleanings during slower hours so the kitchen keeps running.
Older low-rise buildings among the towers
Between the new towers are 19th and early 20th-century buildings with storefronts and offices or apartments above. They often have original cast iron drains, steam boilers and gas piping that falls under Local Law 152. Their problems look nothing like a new tower's: corroded stacks, cold radiators and slow building sewers. We service both kinds of building.

Plumbing in Downtown Brooklyn: FAQ
Can you provide a certificate of insurance before starting work in our building?
Yes. We provide certificates of insurance naming the building, the managing agent or the condo board as required. Send us the building's insurance requirements when you schedule, and we will have the COI ready before the job begins.
How often must backflow preventers be tested?
Every year. New York City requires annual testing of backflow preventers by a certified tester, with the results filed with the city. We test, repair or replace devices that fail, and handle the filing for your property so the record stays current.
Do you service commercial tenants as well as residential units?
Yes. We handle restaurant kitchens, retail spaces, offices and residential units, from a single faucet or toilet to drain lines, water heaters and gas piping. Building managers can set up a property management account that covers all their buildings.
