Water Smells Like Rotten Eggs in Hillsboro Beach

Use the hot-and-cold check

The Florida Department of Health's well-water fact sheet gives a simple rule of thumb that works for any home:

• Hot taps only: the problem is likely in the water heater.
• Strong at first, then fades: often sulfur bacteria in the well or plumbing.
• Constant on hot and cold: likely hydrogen sulfide in the groundwater supplying a well.
• Only through a softener: possibly bacteria in the softener.

On town water, the last two are uncommon, because the town treats and chlorinates its well water before it reaches you.

The water heater explanation

Tank heaters use a sacrificial anode rod to protect the tank. In warm, still water, a reaction at the rod can create hydrogen sulfide. Seasonal homes are especially prone: a heater left on while the owner is away for months gives the reaction plenty of time. Running hot water for a few minutes usually clears it temporarily.

A licensed plumber can flush the tank or swap the rod type. Check the heater manufacturer's guidance first, since changes can affect the warranty.

When it is not the water at all

A smell from just one sink or shower is often the drain or P-trap, not the water. Fill a glass at that tap, step away from the sink and smell it. If the water in the glass is fine, look at the drain.

If your property uses a well

Some properties use private irrigation wells, and Broward County requires permits from the Department of Health for wells 12 inches or smaller, including irrigation wells. Groundwater with hydrogen sulfide is treated with methods chosen from the test, such as aeration or oxidation plus filtration. See well water in Hillsboro Beach and aeration vs. filtration for sulfur smells.

Quick things to try first

• Run the hot water for several minutes and see if the smell fades.
• Note whether it is worse in the morning or after time away.
• Check whether one bathroom or every tap is affected.

Bring those notes to the test; they speed up the diagnosis.

If the house was closed for the summer, also note whether the water heater was left on. A heater left on in an empty home is one of the most common setups for this smell.

What Jorge checks

He smells and tests hot and cold taps, checks chlorine and pH, and looks at the water heater's age and use. If the heater is the cause, he tells you and you may not need any equipment. Call, text or WhatsApp (305) 793-5974.
