7 Best RV Water Bladders for Carrying More Fresh Water

When you’re boondocking, you typically have a plan to keep water in your freshwater tanks. However, many campgrounds and campsites across the country don’t have easy access to fresh water. Using an RV water bladder can be an extremely convenient and effective way to ensure you don’t run out of water while RVing.

Today we’re looking at seven of the best RV water bladders we think you should consider. Let’s get started!

What Is an RV Water Bladder? 

An RV water bladder is a collapsible bag for storing water. These come in varying sizes and materials but are great options for RVers who frequently find themselves RVing in locations without a water connection at their campsite.

Whether you’re boondocking or camping in a more primitive campground, a water bladder can help avoid multiple trips or having to pack up your entire RV to take it to a water source.

While water bladders can be rather compact while in storage, they take up a generous amount of space when in use (some of the largest collapsible bags can hold upwards of over 250 gallons!). You’ll need a good amount of room in the bed of your truck to hold the bladder as you transport it from the water source to your RV.

How Do I Refill My Boondocking Water From a Bladder? 

There are a couple of options for refilling your RV’s water tank from a bladder while boondocking. Depending on your RV, you can use gravity or a water pump to get the job done.

Some RVs come with water systems that allow you to use the onboard water pump to siphon water into the fresh water tank. You can connect the water bladder to the RV using a siphoning hose, and the water pump will do all of the work for you.

Depending on your water pump and how much water you’re pumping, this can take some time and may require you to give your water pump a break. If your RV doesn’t have this feature, you can also achieve the same results from an external water pump.

Another method is to use gravity to do the work for you. Because gravity forces things down, this will only work if the water is higher than the water connection. This isn’t an excellent option for water bladders as they can be cumbersome. This is a great option if you’re only adding a few gallons at a time to top off your water tanks.

Other Ways to Carry More Water in an RV

There are a few simple solutions for carrying more water in an RV. One relatively inexpensive option is to stock up on water jugs. You can typically find drinking water-safe jugs ranging in one to five gallons online or at your local big-box retailer.

These are great options as they’re small, and you can easily store them until you find a filling station. However, because these are often one to five gallons, you’ll need to make quite a few trips or have several to fill up a large RV water tank.

If you have the space, a water tank is a great option. These tanks are typically over 35 gallons and sit in the bed of your truck. While you’re losing bed space, you’re gaining the ability to transport a large amount of water to your camper.

You won’t have to pack up camp and tow your RV to a water source. You can use an onboard or external water pump to siphon water from the portable water tank into your RV’s water tank.

Losing bed space and the premium price of these water tanks often prevent many RVers from pulling the trigger on this method.

We also recommend practicing water-saving boondocking methods for cooking, cleaning, and more when camping without hookups to reduce the risk of running out unexpectedly.

Water Bladder VS Water Jugs

Is an RV Water Bladder Worth It?

Using an RV water bladder is most definitely worth it. The more trips you have to take back and forth to a water source, the longer it will take for you to fill up your tanks. Being able to quickly and efficiently fill up your fresh water tank means you’ll have more time for adventuring and enjoying the RV lifestyle.

If you’re planning to use your RV in remote locations or campsites without easy access to water, we highly recommend being proactive and having a water bladder on hand.
