If you are a homeowner with private well water at your residence, you may assume that water directly from the earth will be pure and crystal clear. This isn’t always the case. Often, this “natural” water may smell or taste bad. When investigating smelly water issues, it is important to check both hot and cold water faucets for odors. Learn what to do when smelly hot water becomes a problem in your home.
Before you go straight to the source of your smelly hot water, check around your house to ensure that nothing inside your home is causing the smell. If you’ve determined without a doubt that your water is the culprit, it may stink due to one of the following reasons.
The hot water line can be a source of odors, particularly if bacteria are growing within it or the water heater.
You may be familiar with hydrogen sulfide, a form of sulfur that causes a “rotten egg” smell, but you may have never heard of this sewage-like stink linked to hot water in a home. This compound is very common in homes with untreated well water, and if it is not treated adequately, it can pose a danger to human health.
A smelly hot water problem in hot water systems usually originates from a sulfur or iron bacteria buildup. These bacteria can thrive in some water heaters and give off hydrogen sulfide gas that smells like rotten eggs.
Due to the presence of sulfate and bacteria, the water heater tank can create conditions conducive to the production of hydrogen sulfide gas. The anode in the tank helps prevent corrosion while facilitating chemical reactions.
This can happen to your hot water tank for two reasons: The water may have sat unused in the tank for too long, or, in the case of well water, forgoing chlorine treatments can lead to the proliferation of sulfate bacteria.
In some cases, the magnesium anode rod inside a water softener system can combine with the compounds in the soft water to form hydrogen sulfide gas.
Identifying the source of the smell in your water is crucial to determining the best course of action to eliminate it. Here are some steps to help you identify the source of the smell:
By systematically checking these potential sources, you can pinpoint the cause of the smell and take appropriate action to eliminate it.
Water heater issues can cause a range of problems, including smelly water. Here are some common issues that can cause smelly water:
Addressing these common water heater issues can eliminate the source of the smelly water and ensure your hot water remains clean and odor-free.
Fortunately, if the problem is in your water heater, treating it is as easy as installing a small, inexpensive screen filter and a bottle of hydrogen peroxide.
Using a chlorine bleach solution can effectively flushing and disinfect water heaters, but caution should be exercised, and professional assistance may be required.
The Water Heater Odor Killer Filter is a chemically resistant pre-filter designed to withstand high temperatures and chemical concentrations. As such, it can be a very effective system for purging bacteria and odors from a contaminated water heater.
Simply install the filter on the cold line to the water heater, unscrew the bottom sump, and add 1 pint of 3% hydrogen peroxide (available at any drug store). Then, turn your water back on and run hot water for several minutes before allowing your water heater to sit for about 3 – 4 hours.
Well water can be perfectly safe to drink and use every day if it is treated, but owners often wrongly assume that they do not need to take action because well water is safer than other sources of water.
According to the CDC, well owners are responsible for ensuring that water from their properties is safe to drink. It is important to have your water issues tested, treated, and addressed before they create bigger problems for your family.
If your cold well water smells bad, you have several good options to completely eliminate this odor:
