Sulfuric Smell in Van

Sulfuric Smell in Van

Confirmed Issue:
There is a sulfuric smell inside the van (like rotten eggs or sewer water).

Affected Units:

Any Vandoit van

Issue Explanation:

A sulfuric smell can come from a couple of different sources and can trigger the carbon monoxide alarm.  These sources--and their resolutions--are listed below from least to most involved.

Resolution:

1. If the gray water tank has not been emptied or cleaned out in a while, the tank, the sink, or the black hose leading from the sink to the tank may be the source of the smell.  Empty the tank and clean it out with a solution of water and vinegar or water and a small amount of bleach.



2. A buildup of sediment in the water heater may be the source of the smell.  Follow the steps in this article under To Winterize the Hot Water Tank to remove the water heater, empty it, and check for sediment as the source of the smell: https://vandoit.zohodesk.com/portal/en/kb/articles/winterizing-your-water-system

For the Bosch 2.7-gallon Tronic mini-tank water heater, annual maintenance includes inspecting the anode rod, checking for leaks, and potentially flushing the tank, especially if you use hard water. For instructions on this maintenance, see this link: https://vandoit.zohodesk.com/portal/en/kb/articles/bosch-tronic-3000t-water-heater-manual


3. If your van has the AGM battery system, a leaking battery could be the source of the smell.  See this article for more information: https://vandoit.zohodesk.com/portal/en/kb/articles/leaking-battery



4. If the above sources have been ruled out as the source of the smell, there is a possibility that the Ford chassis battery, located under the driver's seat, may be the source.  Common signs are leaking acid or strong sulfuric smell only around or near the driver's seat.  If you suspect this may be the case, take your van to a local Ford dealership to have the battery inspected.  Increase ventilation in the van until a fix can be found.

If, after checking these potential sources, you are still unable to determine the source of the smell, submit a ticket through the Customer Support portal or email support@vandoit.com with a description and photos of the issue you are encountering.
