PEMBROKE PARK · SULFUR SMELL

Water Smells Like Rotten Eggs in Pembroke Park

In a Pembroke Park home or business on county water, a rotten-egg smell from the hot tap is almost always the water heater, where bacteria reacting with the anode rod can produce hydrogen sulfide. A smell from the drain, not the water, is another common cause. Water made at Hollywood's plant and delivered by Broward County is treated and disinfected, so sulfur in both hot and cold county water is unusual. A quick check narrows it down.

Checklist: water or drain?

  1. Fill a glass at the sink, step away and smell the glass. If the glass smells, it is the water. If only the sink area smells, it is likely the drain.
  2. Repeat with hot and cold water.
  3. Try another faucet in the house.

Do this at more than one sink. If only one bathroom smells, the drain or trap there is the likely cause.

Water heater options

A plumber can flush the heater, replace the anode with a different type, or adjust settings. A filter is not the fix for a water heater smell, and Jorge will say so.

Do not remove or alter an anode rod yourself without the heater maker's guidance; the rod protects the tank from corrosion.

If it is the county water

Hollywood's plant lime-softens, membrane-filters and RO-treats the water before chloramines are added. A true sulfur smell in cold county water would be unusual. Report it to Broward County WWS at 954-831-3250.

Wells

Sprinklers fed by a well can smell when they run. For a well that supplies a building, aeration, oxidation and carbon are common approaches, chosen by test. See aeration vs. filtration and well water.

After a vacancy or a new heater

Water that sits in a heater for weeks, in a home or business that was closed, often smells on the first draw. Run the hot taps for several minutes. A new heater can also behave differently from the old one. If the smell keeps returning, talk to a plumber about the anode rod type.

Common questions

Why does only my hot water smell?

Most often a water heater anode reaction. A plumber can fix it.

Could it be my drain?

Yes. Smell a glass of water away from the sink to tell the difference.

Is the smell harmful?

The Florida Department of Health says sulfur bacteria are not harmful. Wells should still be lab-tested for bacteria.

Who do I call about county water odor?

Broward County Water and Wastewater Services at 954-831-3250.

Can a softener cause sulfur smell?

The Florida Department of Health notes that sulfur bacteria in a water softener can cause a smell in softened water only.
