If you think the hydrogen sulfide is being created in your hot water heater, it’s time to call plumbing contractors who are licensed to deal with this problem. In this instance, you cannot do the job yourself!There are three possible plumbing problems in your hot water heater that could be causing the gas: the anode needs replacing, the water heater needs to be flushed or the temperature needs to be increased briefly. Plumbers or heating and cooling experts will be able to identify the problem and complete the appropriate fixes.
Problems in a Well or Water Distribution System
When the hydrogen sulfide gas is coming from a well or water distribution system, it needs to be disinfected with a strong chlorine solution. If you have a well, it may also need to be physically scrubbed with special chemicals. Agitation of the water may be necessary as well.
Problems with Water Treatments
If your water treatment – such as a water softener – is the problem, contact the manufacturer or installer for disinfecting treatment devices.
Problems in GroundwaterYou have three options if the hydrogen sulfide gases are in your groundwater:
- Install an activated carbon filter – The gas will become trapped in the carbon filter and stay out of your home. Be aware of what size filter you choose, as small filters will only last a few days to a few weeks, while a larger filter can last for years.
- Install an oxidizing filter – The best example of this is a manganese greensand filter. It is normally used to treat iron problems in water, but will filter the sulfur out of hydrogen sulfide gas and will trap the sulfur pieces.
- Install an oxidation filtration system – One step up from a simple filter is to install a full system. It will use a chemical feed pump to inject oxidizing chemicals, usually chlorine, into the water supply before it reaches a mixing or storage tank.
