Bacteria can easily grow in standing water, so it’s important to keep freshwater levels low and regularly replace the water if there are any changes in color or smell.
It’s also essential to ensure that your fresh water in RV is connected to a clean and safe source of drinking water. Cross-contamination from outside sources can occur if connections are NOT properly maintained or inspected regularly.
Storing water in your RV tank for an extended period can lead to the buildup of algae and sediment. They can come from the natural environment or from the storage tank itself.
Generally speaking, you should aim to keep the water in your RV fresh water tank for no longer than 2 weeks at a time. After this point, replacing it with a NEW drinking water supply is best.
