We experienced showering and we smell a faint amount of sewage water in our bathroom. We start to think that it’s the water reacting to our floor tiles, but it’s not.
Then, one tired evening we decide to take a bath and help ourselves with some relaxation, only to fill the tub with a heightened scent of dirty water. That is not exactly because our water supply is contaminated, it could be caused by our water heater.
How to add hydrogen peroxide to water heaters is great knowledge that can help us keep the contamination away from our heated water.
If our cold water starts smelling like sewage, then there is a big possibility that the water supply is contaminated. However, if it starts happening to our heated water, then there must be a reaction happening within our water heating system.
What is softened water?
This is a type of water that was treated to remove calcium, magnesium, and certain metal cations in hard water. It makes use of lime softening or ion-exchange resins that are achieved by using nanofiltration or reverse osmosis.
Softened water can sometimes emit this disgusting smell. Usually, softened water accumulates hydrogen sulfide gas that gives off that dirty water scent.
Why Use Hydrogen Per Oxide?
Anode rod is a part of our water heater system that draws corrosive agents in the water. Over time, the anode corrodes, concentrating all corrosive agents to itself making the water heater clean.
The role of an anode rod is to become sacrificial, absorbing or attracting corrosive materials in the water. However, the anode rod will soon look like it has been eaten by bacteria.
Once it has nothing left, it will start emitting a smell that goes to our heated water. This can be caused by a reaction between the rod and the sulfate from the water, therefore, making the hot water have its unbearable scent.
The most common type of anode rod that comes with our water heater is aluminum. Aluminum corrodes the slowest but it is meant to be paired up with hydrogen peroxide to remove the sewage scent from our heated water.
The reason why aluminum is packaged together with our new water heater is that it is very cheap. If the water sewage smell becomes very strong and unacceptable, changing the anode rod is the step to take.
However, the use of hydrogen peroxide is to combat Sulfur Bacteria. Sulfur Bacteria is natural to our water supply.
When it comes in contact with our water heater it can make it its breeding ground, therefore increasing hydrogen sulfide gases. In order to eliminate the smell caused by bacteria, add hydrogen peroxide in cleaning the tank out.
Here are 8 easy steps on how to add hydrogen peroxide to our water heater:
- Shut it down. Do not work repairs with anything electrical without shutting it off. The same goes for gas water heaters. We can turn off the electric water heater through the circuit breakers or if it is an easy plugged-in type to electrical sockets, please unplug it. For gas, make sure that we turn it off from the pilot.
- Drain thoroughly the water heater tank and close the valve after we have drained. Before we drain out the water, make sure that it has cooled down to avoid third-degree burns.
- Make use of 3% hydrogen peroxide. An exact measurement of 2 quarts per 40 gallons should be followed. It will still depend on the size of our water heater tank. Add it to our tank.
- Open the cold water supply and fill up the tank.
- Let the water seep in with the hydrogen peroxide. Do not turn on the heater yet. This is to let the hydrogen peroxide take care of the nasty smell. Let it sit for about 2-3 hours to have its full effect.
- Flush out the tank. After waiting 2 hours, turn on our heated water faucet and our cold water valve and flush out the tank. This will clean not just the tank but also our pipes.
- Fill up the tank. When we’re no longer smelling the dirty water scent, we can fill the tank up once again for usage. Test the scent from the hot water faucet. If the scent is still lingering, keep on flushing out the water heater tank.
- Turn the power on. Once it’s all done, turn the power supply on back to our water heater. Observe if the smell has been removed from the heated water.
In The End
Contrary to popular belief, heating does not always kill bacteria. In this case, sulfur bacteria thrive in heated water tanks that populate over time creating sulfide gas.
How to put hydrogen peroxide in our water heater is learning that will make life easier for us when cleaning out our water heater tank. It is advisable to maintain our water heater by performing a routine clean-up in its tank at least once a year.
