NYC Plumbing and Heating Experts You Can Call 24 Hours a Day

Common plumbing problems, and what they mean

Water stain on the ceiling

Usually a supply or waste leak in the unit above — isolate it before the ceiling fails.

Drains gurgling across the property

Typically a main line restriction, not a single fixture clog.

Radiators cold at the top of the building

Often a boiler or near-boiler piping problem, not a radiator problem.

Hot water that runs out fast

Sediment or a failing heater — worth checking before it leaks.

Maintenance prevents most emergencies

• Know where your shutoff valves are, and test them before you need them.
• Insulate exposed pipes before winter to reduce freeze risk.
• Keep grease out of kitchen lines — it is the leading cause of restaurant backups.
• Have building drains and heating plant checked ahead of the season, not during it.
• Address slow drains early; recurring clogs point to a defect in the line.
