Understanding The Need To Keep Fresh Water In Your RV

Keeping fresh water in your RV tank is essential for maintaining a safe and clean environment. To better understand why it is important to keep fresh water in the tank, let’s look at some of its benefits.

Health Benefits

Having clean and fresh water in your RV fresh water tank is essential for maintaining a healthy environment

Having adequate fresh water will help ensure proper sanitation, minimize disease risk, and reduce the chances of contamination.

Additionally, regular water supply maintenance will help PREVENT bacteria from growing and spreading in the tank.

Cost Savings

Keeping fresh water in your RV fresh water tank can also save money by reducing waste.

Regularly replacing old water with new prevents contaminants from building up and reduces the need for EXPENSIVE repairs or replacements. Additionally, not purchasing bottled drinking water can significantly reduce expenses over time.

Convenience

Having a clean and fresh water supply will also help provide greater convenience. 

Not having to worry about the safety of your drinking water will make it easier to enjoy your RVing adventures and not have to STOCK up on bottled water constantly.

Minimizes Waste

Regularly replacing the water in your RV freshwater tank will also help minimize waste. Not regularly replacing water bottles eliminates the need for additional packaging and containers, thereby REDUCING your carbon footprint [1].

Additionally, you’ll be able to use less energy to heat up or cool down freshwater tanks, resulting in fewer resources being used overall.

What To Look Out For When Storing Water In Your Rv Tank

What To Look Out For When Storing Water In Your Rv Tank

When storing fresh water in your RV fresh water tank, you must watch out for potential problems. These issues could include the following:

Bacterial Growth

Bacteria can easily GROW in standing water, so it’s important to keep the freshwater levels low and regularly replace the water. If you notice any changes in the color or smell of the water, it’s best to replace it with a new supply.

Contamination From Outside Sources

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.

Algae And Sediment Buildup

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.

These elements can cause CONTAMINANTS to enter the drinking water, making it unsafe for consumption.

Corrosion Of The Tank Itself

Storing water in your RV tank for an extended period can also lead to corrosion. Corrosion occurs when the metal components of the tank start to rust due to oxidation.

This process can weaken the structure and integrity of the tank, leading to LEAKS and other damage.

Stagnation

Stagnation can occur when water is stored in your RV’s fresh water tank for an extended period. This happens because NO constant flow of fresh water enters and leaves the freshwater tank, leading to reduced oxygen levels in the water.

As a result, bacteria and other microorganisms can start to grow and spread, resulting in unpleasant odors or even contamination.

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.

However, if you are using bottled or filtered water, it can be kept in your RV’s tank for up to 8 weeks before needing to be replaced.

It’s important to regularly inspect the water and ensure that it remains fresh and clean throughout this time. This can be done by smelling, tasting or testing the water on a regular basis.

Factors That Affect How Long Water Can Be Stored In An Rv

Factors That Affect How Long Water Can Be Stored In An Rv

The amount of time you can store fresh water in your RV tank depends on several FACTORS, such as the size of the fresh water tank, where it’s located, and how often you use it.

Take a look at each of these factors and how they affect how long water can be stored in an RV:

Tank Size

The size of the fresh water tank plays a vital role in determining how long water can be stored. Smaller tanks will require more FREQUENT replacements, while larger tanks have a higher capacity and can store water for extended periods.

Location Of The Tank

The fresh water tank‘s location also determines how long water can be stored. The grey water tank located outside is at a GREATER risk of contamination from natural elements like dirt, leaves, or even wild animals.

For this reason, RV owners should ensure that their tanks are positioned in an area PROTECTED from potential contaminants if they want to store fresh water for extended periods.

Usage Frequency

The frequency of usage also affects how long water can be stored in an RV fresh water tank. If the tank is used more OFTEN, it must be cleaned and replaced more often.

Water Source Quality

The quality of the water source from which you draw your drinking water is also IMPORTANT in determining how long it can be stored.

If you draw your water from an unreliable or contaminated source, it’s best to REPLACE it more regularly than using a reliable and safe source.

External Temperature

Finally, the external temperature can also affect how long water can be stored in a fresh water tank. In hot climates, the water can evaporate more QUICKLY and become contaminated faster than in cooler climates [2].

It’s best to replace the water in your RV’s fresh water tank more frequently if you live in a hotter climate.

Pro Tip: Check your local weather forecast before filling your RV freshwater tank to plan for potential temperature changes.
