As a homeowner with years of experience maintaining water heaters, I’ve found that regularly cleaning and flushing the tank is essential. Using vinegar for this task is a cost-effective and efficient method that has worked well in my home. Flushing your water heater with vinegar not only clears sediment but also extends the life of the appliance.
This simple trick will help you eliminate the sediment inside the tank. However, if not handled regularly, this sediment will cause problems for your unit.
Some problems are less hot water, broken machines, and not appropriately heated water. Therefore, you need to make time to flush the unit yourself and clean your water heater.
How to Flush Water Heater with Vinegar
Sediment build-up can lead to reduced hot water output and increased energy consumption. In my experience, regularly cleaning both gas and electric water heaters has helped avoid these problems. Once, I noticed that my water wasn’t heating properly. After a quick flush using vinegar, the performance improved significantly.
Before that, you must also know what ingredients and tools to use for this tutorial. The things you need to have are:
- Hose
- Bucket
- Step tool
- Vinegar
- Socket wrench
- Funnel
Then, here are the steps you could take to flush the water heater with vinegar. Follow it accordingly for the best result.
- The first thing to do is to turn off the water heater. If your unit is electrical, use the circuit breaker panel, or close the gas shutoff valve if you use a gas water heater.
- Before starting the process, always close the water supply. I’ve learned from experience that leaving the supply open can make the flushing process ineffective and even cause water damage. Shutting off the supply is a crucial step that ensures you can thoroughly clean the tank.
- Then, you could drain the tank. The drain valve is on the bottom of the tank. Use the hose and connect it to the drain valve. Make sure to drain the water outside of the house. Wait several minutes.
- If the water heater’s anode rod is finished, you can remove it. Find a lid at the top of the hot water tank and remove it. Also, do not forget to remove the insulating material if your unit has one.
- Loosen the anode rod using the socket wrench and slide this part out.
- The next step is to fill the anode rod with vinegar. Again, you could use the finger and place it into the anode rod. Finally, pour 3 gallons of vinegar into the anode rod chamber.
- Insert the anode rod again and then remove the funnel.
- Replace the insulating material and the cover.
- After that, open the main valve and let the hot water into the tank for several minutes.
- Let it be for at least 6 hours to remove the sediment properly.
- Flush the water heater thoroughly. In my experience, using a garden hose to drain the sediment-laden water outside is effective. One user on an online forum mentioned that they noticed a significant improvement in their water heater’s efficiency after following this method.
- Fill the water supply and run it as usual. Your water heater should be clean by now.
What Kind of Vinegar to Flush Tankless Water Heater
If you already know what to do with the vinegar and the tank, now it is time to understand what kind of vinegar to use for this tutorial. You are on the wrong track if you think regular white vinegar is correct.
It is common to use ACV or apple cider vinegar to flush the water heater tank. This kind of vinegar is slightly more alkaline than the other one. Therefore, it will not corrupt the metal aggressively like white vinegar. ACV will help clean the tank without eating away the parts.
However, you could also use the water heater sediment cleaner from the store. This option is much easier if you want special tools and materials. Nevertheless, the two options are both good.
Additional Tips:
- Using a funnel to pour vinegar directly into the anode rod chamber is a game-changer. In a similar maintenance session, I once faced difficulty with sediment that didn’t dissolve easily. After letting the vinegar sit for 6 hours, the sediment loosened, and flushing it out was a breeze.
- Flushing your water heater with vinegar is a natural and effective way to deal with sediment buildup. This method is especially beneficial for those with hard water issues.
- Regular maintenance, including an annual flush, can significantly extend the life of your water heater and improve its efficiency.
- If you’re uncomfortable performing this maintenance, consider hiring a professional to ensure it’s done safely and correctly.
Following these steps, you can flush your water heater with vinegar, improving its performance and longevity. Regular maintenance is key to avoiding common water heater issues and ensuring you always have access to hot water when needed.
Conclusion
Knowing how to flush a water heater with vinegar is a simple hack for a house owner. However, being able to do the work yourself will help you go through it independently, especially if you are about to face a cold winter in your area. It is a little trick to keep the body warm.
