Water heater not working in the Bronx? Start here

In Bronx houses and small buildings, hot water usually comes from a gas tank water heater or from the boiler (an indirect tank or a tankless coil). Knowing which one you have is the first step.

Renting? Hot water, like heat, is your landlord's responsibility year-round. Tell your landlord or super first, in writing. If it isn't fixed, report it to 311. Our matching is for owners and landlords.

Emergency? Gas smell, CO alarm, fire, sparking or flooding: get to safety and call 911 first.

Common causes of no hot water

  • Pilot light out or a failed thermocouple or flame sensor on a gas tank.
  • Gas valve or control set to off or vacation mode, or failed.
  • Tripped breaker or a burned-out element on electric models.
  • Sediment built up in the tank, causing rumbling and less hot water.
  • Boiler-fed hot water: if the boiler is off or faulty, hot water stops too.
  • Broken dip tube or a mixing valve problem, which gives you lukewarm water.

What you can safely check

  1. Look at the control knob: it should be on, not set to pilot or vacation.
  2. Many newer gas heaters have a viewing window, so see whether there's a flame. Follow the lighting steps printed on the tank's label only if you're comfortable doing it, and never if you smell gas.
  3. Electric: check the breaker. Reset it once only.
  4. If hot water comes from your boiler, check whether the heat is working too.

Warning signs: stop and call a pro

  • Smell of gas: leave, then call 911 and your gas utility from outside.
  • Water pooling under the tank, or rusty water at the base.
  • The temperature and pressure (T&P) relief valve on the side discharging. Never cap or plug it.
  • Soot or scorch marks around the burner, or a CO alarm going off.

What a repair or replacement involves

A plumber may replace a thermocouple, gas control, element or anode, flush sediment, or recommend replacing the tank if it's leaking. In NYC, gas water heater work must be done by or under a DOB Licensed Master Plumber, and replacements normally need a DOB-filed permit plus correct venting and a code-compliant relief valve. The plumber should handle the permit. Prices vary by type, size and access (basement stairs matter!), so get a written quote.

Questions

How hot does my Bronx landlord have to keep the water?

NYC requires landlords to provide hot water at 120°F or more year-round. If you don't have it, tell the landlord and then file a complaint with 311.

Can I relight the pilot myself?

If your model has a manual pilot and the label gives lighting steps, many owners do. Never do it if you smell gas, and call a pro if it won't stay lit.

Do I need a permit to replace a water heater in NYC?

Generally yes, filed by a licensed master plumber. Ask the plumber to confirm in the quote.
