Just how hydrogen sulfide got into your water heater

Our water system contains a naturally-occurring ion called sulfate. In small amounts, sulfate doesn’t posture any kind of major health dangers to human beings and also is virtually undetected.

However, two problems can cause sulfates to become hydrogen sulfide (the stinky gas).

  • High sulfur-reducing microorganisms (SRB) count in water
  • Worn away magnesium or aluminum anode rod

Issue # 1: High SRB matter in water

Sulfur-reducing bacteria (SRB) get energy by feeding off of sulfates, ultimately minimizing them to hydrogen sulfide. If your house’s supply of water has a high SRB count, that might describe why you’re getting whiffs of that rotten egg odor.

Regional water treatment centers normally eliminate most of the SRB discovered in your water using chlorine and various other chemicals. Some water supplies (such as water from wells) have greater quantities of SRB because the water is without treatment.

Problem # 2: Rusty magnesium or aluminum anode rod

Conventional water heaters have a protective element called a sacrificial anode rod. The objective of the anode rod is to attract harsh minerals to it to make sure that the pole rusts instead of the internal lining of the container.

Several anode rods are constructed from magnesium or aluminum. When these poles wear away, the steels react with the sulfates in the water, turning the sulfate right into hydrogen sulfide.

Now that you know just how hydrogen sulfide enters your tank, allow’s check out how to do away with that horrible odor

 

Just how to eliminate the rotten egg scent.

Preventative method # 2: Add a water filtration system

If your water naturally has a high level of SRB or you are constantly getting the rotten egg scent, you may require a water filtration system.

There are numerous types of water filtration systems, and also some concentrate on removing hydrogen sulfide. You’ll need to consult with a plumber to find which sort of purifier is best for your needs.
