There are many components of an RV that RVers love to utilize, but one of the most essential and convenient can be the freshwater tank. A freshwater tank is a tank that holds freshwater… Wow, thanks captain obvious. It really is just that self-explanatory, and it can come in handy if you want to use water without having access to a water hook-up at a campsite (or anywhere else).

The question is for RVers that want to do this is how can they fill up their freshwater tank in their RV to be able to utilize the water throughout their camper? Well, how to fill water tank in RV is not too complicated of an endeavor, and we want to break down everything you need and should know about it.

So, we’re sure you know the drill at this point if you’ve read a lot of our content. Let’s get this show on the road.

How to fill water tank in an RV?

Yep. Don’t worry as we’re going to get into the meat and potatoes right away. We figure there’s no time like the present, so let’s talk about what you need to do to fill that good old tank up with water. After all, the freshwater tank doesn’t do much good if there’s no water inside. Again, we know, thanks captain obvious.

Step #1: Find the intake valve: Okay, so you’re going to need a freshwater hose. For the record, and this is something that we’ll also get into a little later, it’s wise to use a separate hose for your freshwater system. You don’t want to contaminate your water, after all. Anyway, with this hose in hand, you’re going to need to attach it to the intake valve (which may simply be labeled as city water). The other end of the hose needs to be attached to your water spigot.

Step #2: Turn on the spigot: Now that you’ve got the hose attached, you can turn on the spigot to allow the water to flow. Use the tank indicators in the panel of your RV to keep an eye on when you’ll need to shut off the water. To make this easier, you can have someone else stand next to the spigot and simply tell them when to shut off the valve. It’s wise to not overfill the tank.

Regarding how much you’re going to want to fill the water tank, it kind of depends on your situation. If you’re boondocking, you’ll probably want to fill it up completely as you won’t have access to more water. However, if you just want some water on the road, you could fill it up halfway, for example, and then use a city water connection after that.

Keep in mind that a full freshwater tank can add a lot of weight to your RV on the road. Hence, if you don’t have to fill it up completely, you don’t have to in order to save some weight.

Keep those hoses separate

As mentioned, you really don’t want to mess around with contaminating your water. A safe way to do that is to ensure that you have a freshwater hose that’s separate from everything else. For example, you don’t want to use this hose for cleaning out a septic hose or even cleaning your RV.

Additionally, it’s wise to store the hose away from other hoses. Simply put, you just don’t want to mess with that good old freshwater.

Using a city water connection

How to fill water tank in RV isn’t going to be much of an issue if you have access to a city water connection. If you’re staying at an RV campground, for example, most of them will provide you with such a connection. To gain access to the city water, you’re more or less going to do the same thing.

From the campsite faucet to the city water intake on your RV, you’re going to want to connect a freshwater hose. One small note is that you want to ensure that the valve is turned to the city water setting.

A good RV water pump is also going to factor in

Now, that’s really all you have to do to either fill up your water tank or use a city water connection if possible. However, there’s also something that can factor into everything and that’s the RV water pump. There are a few reasons why RVers will come to love the water pump in their system.

Without a water source and with your freshwater tanks filled up with water, the water pump is going to allow you to use the water throughout your RV. From your faucets to your showerhead to your toilet or toilets, the pump is going to deliver the pressure needed.

Using the water pump even with access to city water can boost water pressure if it’s low when using the city water, you’re using.

Final thoughts

How to fill water tank in RV ended up being pretty simple, yes? There are things here and there that can complicate the process, sure, but filling it up really is a fairly easy process. Of course, you may not even need to do that if you have access to a city water connection and just want to utilize that water.

However, sometimes the best RVing happens in the middle of nowhere when you don’t have access to water. Either way, you now know and understand how simple the task really is! There’s something else that we want to mention, though, and that’s how long you should keep freshwater in your RV tank.
