That smelly hot water usually points to a common issue inside your water heater. The good news? It’s definitely fixable. At GEI Plumbing Services, we help homeowners deal with this exact problem ALL the time, more importantly the solution is usually easier than most people think.
Figure Out If It’s Just The Hot Water
Before stressing about the issue, do this quick test. Turn on both the hot and cold water from the same faucet and let it run for a few seconds. Analyze the smell from both the hot and cold water. If you notice the smell is only coming from the hot water then most likely the issue is your water heater not your main water line or pipes.
Why Your Water Heater Might Be Causing the Smell
It’s definitely possible for bacteria to grow inside your water heater. This is even more common if your tank is full of mineral build up or has been sitting for a long time. Now, this does not mean your smelly hot water is unsafe. Your water heater is just letting you know that it needs to be assessed.
The way something like this can happen is when the bacteria in your tank reacts with the metal in your water heater, which is most likely the anode rod. That will produce a rotten egg or sulfur smell which is hydrogen sulfide gas.
Once you are completely sure that smell is your hot water follow the steps below to see if this can be resolved on your own.
Step 1: Flush the tank
The first thing we usually recommend is a full flush of your water heater. Here’s what that looks like:
- Turn off the water heater.
- Shut the cold water valve.
- Attach a hose to the drain valve and empty the tank.
- Fill it back up with clean water.
- Repeat 1–2 times if needed.
This process will flush out sediment that has been building up and a portion of the bacteria that can be causing the smell.
Step 2: Disinfect the tank
Once a basic flush has been completed and the smell still persists the next step is to disenfect.
You can use bleach or white vinegar to get this step completed. Add the cleaning solution of your choice and let it sit for a while in your tank (a few hours). Once you feel it is ready, drain the tank again and rinse it thoroughly. Most of the time this process is sufficient enough to remove the smell.
Step 3: Check the Anode Rod
All water heaters have a part called an anode rod. The purpose of the anode rod is to attract corrosion and minerals so your tank can stay in good condition for as long as possible. Over time with normal wear and tear it can actually make the odor worse.
If you know that your anode rod is older than 3-5 years it could be time to replace it. Here at GEI Plumbing Services we can also install a powered anode rod. It does not corrode like the traditional version and it helps with odors forever!
