One of the most important skills a new RVer learns is how to get city water into your RV. Then you can use it for washing, drinking, cleaning, etc. So you have to be able to use the RV water hookup in the campground where you are staying.

In most cases, the campground RV water hookup will be a faucet in your campsite. When you connect an RV water hose to the faucet and then to your rig, you are all set.

But I am going to show you 3 things that will improve your campground water connection. They will enhance your safety and the safety of your RV. And they can also help make your RV life more convenient.

RV Water Hookup Must-Have #1 -RV Water Pressure Regulator

The first must-have for your RV water connection is an RV water pressure regulator. Why are these devices needed?

Simply because many campgrounds will have a water connection that has too much pressure in the line.

And the danger is that if you hook up to this high RV water pressure, you may damage your rig’s plumbing. If that happens, it is usually not an inexpensive repair.

So an RV water pressure regulator makes sure that the water pressure going into your RV is safe.

It attaches easily to any RV water hose. And then it regulates the pressure so that your RV’s plumbing will not be damaged when you hookup.

These little devices are very cheap insurance against very costly repair bills. So there is no reason why you would not want to use them every time you hookup to campground water.

RV Water Hookup Must-Have #2 – A Water Filter

As we travel around in our RV, we use several campground water hookups. And in most cases, we don’t really know where the water is coming from for that connection.

We also don’t know what condition that water is in either. And that is why it makes sense to use a water filter whenever you connect to a water supply.

There are several kinds of water filters available. Some are very expensive and some are not.

Generally speaking, the more expensive the RV water filter, the more filtration takes place.

Also some require a permanent mount in your RV while other can simply be hooked up to your RV water hose.

I have used a very inexpensive canister RV water filter for a while now. You often see these kind of filters being used by RVers in campgrounds.

They easily fit any water hose, and they can be set up in just minutes. It is true that there are better RV water filters available.

But these RV canister filters do an amazingly good job, especially for the price. They help remove bad taste, while also filtering out odors, chlorine and sediment.

You can always use these inexpensive RV water filters along with other filters as well. So here is the RV canister water filter that I recommend for consideration (just click on the link below to learn more about it):

RV Water Hookup Must-Have #3 – A Dual Water Hose Connection

This next item may not be as essential as the other two for the safety of both you and your rig. But it is a great time and energy saver that every RVer should know about.

I don’t know how many times I have needed to use a water hose to wash something at my campsite. But if I only have a single RV water hookup, it presents a problem.

That is because I will have to use the hose that feeds my fresh water system. That in turn means that I have to take apart the existing water connection.

But if I use a dual hose water connection at the campground faucet, everything is much easier.

All I have to do is just add another hose to the second connection at the faucet. Then I turn the water on to the second hose and I’m all set to go.

I have gotten such good use out of this arrangement and I’m sure that you will too.

Here is a dual water hose connection that you may want to consider (just click on the link below to learn more about it):

RV Water Connection Tips

Having the RV water hookup gear that I mentioned above will help make your campground experience a good one.

But understanding them is even more important. So here is a little more information about the items mentioned above.

There are several kinds of water regulators that can be used for RV camping. And I included links to two of them.

Either one will work for you, but I personally like to use the RV water regulator that has a pressure gauge.

Why? Simply because it gives me more information about the water pressure that is coming from my campground connection. And more control of the water pressure too.

The regulator that has a “Low/Good/High” readout will do the job. But it doesn’t allow you to adjust the pressure going into your rig at the connection.

But the regulator that has the actual water pressure readout will also allow you to adjust the water pressure to fit your situation.

So if your RV is a newer one, you may be able to use a higher water pressure like 60 psi. But if it is older, it may be safer to adjust the pressure to 45 – 50 psi instead to protect your older plumbing.

But at least you know exactly what you are dealing with if you know the correct water pressure at the water connection.

Of course, the water regulator with the actual PSI gauge costs more. But for me, I think it is worth it if you can afford the extra cost.

More Water Connection Tips

Another good tip is to use a 5/8 inch food grade water hose for your RV water hookup.

You will find a lot of water hoses that you could choose from for your RV water connection.

But if it does not specifically state that it is approved for use in food preparation, don’t use it!

This is because some of the materials used for garden and outdoor hoses can be detrimental to your health.

But a food grade hose has to be made with materials that will safely transport the water into your rig without adversely affecting the water quality.

So does the size of the hose make a difference? Yes, it can. If you want the best water pressure possible from your water connection, you should use a 5/8 inch hose.

It’s a little larger than a 1/2 inch hose, but it can make a lot of difference in your faucet and shower water pressure.

The extra diameter allows for more water flow. And since most campgrounds don’t provide the kind of water flow that you experience at home, this is a good thing!

Cold Weather Water Hookups

Cold weather can be a challenge to water connections in RV campgrounds. In fact, when the temperature drops to freezing or below, you need to exercise caution.

This is because the last thing you want is to have your RV water pipes freeze and burst. That kind of problem can be crazy expensive to repair.

So how do you protect your water system in very cold weather? An easy way to do that is to only hook up to the RV water connection long enough to fill up your RVs fresh water tank.

Then remove your hose and keep it in a place where it won’t freeze. When your fresh water tank gets low, hook up again only long enough to fill the tank again.

It can be a little inconvenient to implement this strategy, but it can also prevent a lot of repair headaches.

Some RVers tempt the elements by keeping their water hose connected below freezing. And some get away with it.

But I have had a water filter connected at the faucet burst from water freezing inside it at only 30 degrees.

So I don’t play around with my water connection in very cold weather. And I think you shouldn’t either!

Conclusion

Your campground RV water hookup is very important since you will be using water for so many purposes in your RV. Like bathing, cleaning, washing, and drinking.

So why not make sure that the water coming into your rig is safe for both you and your rig?

A residential water connection requires little to no thought on our part in most cases. But the quality and safety of the water connection for our RV is entirely up to us.

And using these 3 must-have items and my tips for your campground water hookup will make your RV life easier and safer.

Have safe and happy travels my friends!
