Nothing is more frustrating than foul smells emanating from your hot water faucets or near the storage tank. If you detect a rotten egg-like or sulfuric smell in your home, don't worry. This is a common plumbing problem that often indicates hidden water heater issues. At Mr. Rooter Plumbing, we provide quality water heater repair service tailored to your needs. With extensive industry expertise, our licensed technicians leverage expertise and proven techniques to inspect, diagnose, and fix hidden issues before they escalate into bigger problems.
Understanding a Smelly Water Heater
A common cause for the rotten-egg smell is a gas called hydrogen sulfide. While this gas is harmless to living things, it suggests a more serious underlying problem that needs attention. The rotten egg smell is produced when sulfur-reducing bacteria (SRB) feed on compounds containing sulfur in the water. This is common in warm water with low oxygen, making your water heater a prime target. Additionally, ignoring the smell can exacerbate underlying problems, causing failure and other inconveniences.
Common Causes of Foul-Smelling Hot Water
Foul smells coming from your hot water, whether it is in the shower or other faucets, your water tank is likely the culprit. Let’s delve into the common causes to help you maintain a functional system and fresh water year-round.
Sulfur-Reducing Bacteria (SRB)
As mentioned, sulfur-reducing bacteria are the primary cause of foul-smelling hot water. This is a common scenario in homes that rarely use their water tanks, or the thermostat setting is too low. SRB thrives in these conditions, making your water smelly when you run a hot faucet. If you recently returned from a long vacation or business trip, call a plumber to inspect and resolve the problem before it worsens.
The Anode Rod
Water heater manufacturers attach an anode rod inside the tank to attract corrosive elements, protecting the lining. Older or outdated models use aluminum or magnesium rods, which react with the sulfide in water, creating hydrogen sulfide gas. A corroded or rusted anode rod is common, and replacing it can eliminate the foul smells. However, persistent odors indicate a more serious problem that requires professional plumbing repair services.
Sediment Buildup
Over time, minerals and sediments can settle at the bottom of the hot water tank, creating ideal conditions for bacteria to grow. With this in mind, regular flushing and cleaning can prevent buildup and keep your hot water supply fresh. The general rule of thumb is that flushing annually or biannually can prevent such problems. However, this can vary based on a range of factors, hence the need to consult a professional plumber.
Quick Fixes You Should Know
Now that you are familiar with the common causes of smelly water, you can act quickly to prevent nasty surprises. Here are common fixes to help you eliminate bad smells from your hot water.
Run the Hot Water
If you just came home after a long time, run the hot water in your tank to ensure the tank is completely dry before refilling. You can repeat this process if necessary, but a persistent stench is a sign you need professional help.
Turn Up the Heat
Another proven method for getting rid of foul smells is turning up the temperature to 140 degrees Fahrenheit. High temperatures in the tank discourage these bacteria and keep the tank’s interior protected. However, it’s crucial to lower the temperature back to 120 degrees Fahrenheit to prevent scalding and save energy.
