Which RV Water Filter System Is Best For You?

Some kind of RV water filter system is a necessity for RVers. But especially for those who travel a lot. That’s because the water supply at some campgrounds can leave a lot to be desired.

You will find bad tasting and awful smelling water, along with dirty water that has sediment in it. And since we all understand how important it is to have clean water for drinking, bathing and washing, here are a few ways to make sure that your water is safe to use.

Use An RV Cartridge Filter

One of the most popular RV water filter systems in use is an outside cartridge filter. These can be placed somewhere in line with your water hose before it attaches to the RV.

It doesn’t really matter much whether it is attached at the water faucet or by the RV water inlet. Just as long as you have it inline before the water from the campground goes into your RV.

The beauty of these kind of RV water filters is that they will treat all of the water that is going into your rig. So whether it is kitchen or bathroom water, it is being filtered before use.

All you have to do is take a stroll through almost any campground in the country and you will see these filters in use. They are usually blue in color and easily spotted.

And for most people they work very well as they filter down to a 20 micron level. In fact, out of almost 3,000 reviews on Amazon, they have a 4.5 star rating. So a lot of people are happy with what they do.

There are certainly other RV water filter systems that filter water to a higher degree. But for most people this little filter does the job very well. And the cost is affordably low.

So this is a good place to start when filtering the water going into your RV. Just click the links below to read the reviews on these filters.

Higher Quality Whole-RV Filter System

Now if you want to take whole-RV water filtration to another level, there are plenty of options. But one of the most cost-effective is to use a higher level carbon filter that filters down to 5 microns or so.

Some RVers use this filter instead of the blue ones mentioned above. But some also add in this kind of filtration in addition to the blue filter. That’s what we do in our motorhome for our water used for washing and bathing.

Again, for most people this will be just fine. You can either use this kind of filter on the outside of the RV, or install it permanently inside. Either way, it is simple to use and the filter cost is very reasonable.

In fact, they usually last for about 3 months at a time if being used on a regular basis. We use this kind of filter along with the blue filter above and we are happy with the water quality we get for bathing and washing.

You can also use almost any 10 inch filter that you find at a local Home Depot or Lowes store for replacement filters. Check out the reviews on this product at the link below.

High Quality Drinking Water Filtration

But when it comes to our drinking water, most of us want to make sure that it is up to very high standards. So although the above-mentioned filters will work very well, I have another suggestion for your drinking water.

Of course, there are any number of high-dollar water filtration systems available. These include reverse osmosis, 2,3 and 4 stage filters, and even ultraviolet water filtration.

But if you look at the real world reviews of most of these products on Amazon, they are not rated any higher than the ones already covered.

But there is an RV water filter system that will virtually replace all need for bottled water of any kind. And it will be much less expensive in the long run than those high-dollar systems.

It’s called the Berkey water filter and many RVers use it for their everyday drinking water. It is a gravity fed unit so you have to refill it manually. But the resulting water is incredibly clean no matter how dirty it may be going into the filter.

In fact, the Berkey helps eliminate 99.9% of bacteria, heavy metals, pharmaceuticals, viruses, and other water contaminants.

The Berkey RV water filter is also portable allowing it to be used either at home or in the RV. And since it uses no power to operate, it’s perfect for boondockers.

It also is cost-effective as it can filter 6,000 gallons of water before needing a filter replacement. So if you drink two gallons of water a day the filters will last you about 8 years!

And the replacement filters only cost a little over $100. So that means that you get ultra-safe and clean drinking water for about $12/year. You can’t get much less expensive than that!

The Berkey Water Filter VS Installed Filtration

One of the best features about the Berkey water filter system is that it is portable. so it can be moved from the RV to a home, or from one RV to another RV, all without need of any installation!

Reverse osmosis filters and ultraviolet filters actually work very well. But they have to be installed correctly and that usually means professional installation. So you have to pay not only for the filtration system, but the installation as well.

Then if you decide to sell your RV for any reason, you have two choices. (1) You can let the installed water filtration go with the RV, and go out and buy another whole system for the new rig. (2) You have to disassemble the installed system and re-install the old RV plumbing as it was. Then you have to pay again to install the old system in the new RV.

The point is that permanenty installed water filter systems are more suited for home use, not for RVs. This is because people don’t change homes nearly as much as they may change RVs.

This makes the Berkey water filter a great choice as an RV water filter system because of its portability. It can go wherever you go. So if you buy a different RV, just bring along the Berkey. Then you get pure, clean water in the new rig without any installation effort or costs.


When you bring up the subject of RV water filtration, you can get a lot of opinions about what is best. And most RVers seem to think that whatever they are doing is the best way to go.

But the truth is that there are any number of great ways to get fresh, clean, and pure water for RV use these days. Whatever fits your needs and circumstances best will be fine.

But in this article I am trying to approach the subject from a cost-effective point of view. And with that in mind, using cartridge filters for washing and bathing is a cheap way to go. And they work very well as the associated Amazon reviews testify.

Then if you use the Berkey water purification filter, you will also have the best drinking water. And this will come at a very low cost per gallon.

But if you have other suggestions for RV water filter systems that you have found to work well, please mention them in the comments below. We would love to hear about them!

In the meantime, I hope this discussion of RV water filtration has been helpful for you. Have safe and happy travels my friends!

RV Extended Warranty Protection – Yes Or No?

If you bring up the subject of getting RV extended warranty protection for your rig, be prepared. You are most likely going to get some very strong opinions, both for and against. Usually these opinions will come from those who already have made their own decision. And they often feel that what they decided is what everyone else should do as well.

Do you really need an RV extended warranty?

But RV life is more complicated than that. The more you know about RVs, the more you understand that there is no one-size-fits-all solution for everybody.

There are just too many variables to make things that easy. So the two words most often uttered by me in matters like this is “It depends”.

Buying An Extended Warranty Depends On What?

A lot of factors come into play when considering the purchase of an RV extended warranty. If the rig is newer, do you still have a warranty from the manufacturer? Does it cover everything you want to have covered?

If you have an older rig, are there extended warranties still available for that year? Do you have plenty of resources that will allow you to easily handle any major repair that may come up anyway? Then maybe an extended warranty isn’t necessary for you.

What kind of RV do you own? Does it have an engine and drivetrain or not? And the list goes on and on.

Also, what do you want an extended warranty to cover on your RV? Do you want essentially everything covered? Or do you just want the most expensive items that could need to be repaired covered? What are your expectations?

What Are Your Expectations?

Actually, what is often referred to as an RV extended warranty is not really a warranty at all. This is because only the manufacturer can provide a true warranty on their product.

And most extended warranties are offered by a company that is not connected with the manufacturer at all. But the term “extended warranty” has become so accepted in RV culture, there is no other way to describe it now.

Another important thing to realize about RV extended warranties is that they are essentially a form of insurance. You are being insured against a financial loss by the company providing the contract.

And therefore, as an insurance product, you should not expect to make a profit on the warranty purchase. Insurance in its purest form is not an investment. It is a means to manage risk.

The higher the risk that you insure against, the higher the cost of the insurance. It is just that simple. You are accepting a small loss on the cost of the insurance, to prevent the huge loss you are insuring against.

And if you never have to use the extended warranty to cover a high dollar repair, all the better. It just means that you have been very fortunate. You also did not have to deal with the hassle of filing a claim.

Or getting the claim approved, or having the work done properly, etc. So not having the contract pay out more than what you spent for it does not mean that you lost.

It means that you bought peace of mind all through the life of the extended warranty. And you managed your risk well.

What Is And Isn’t Covered?

There are no extended warranties out there that cover everything on the RV. Most contracts will not cover things like your furniture, your possessions in the RV, scratches or chips in the RV paint, etc.

They also will not cover any maintenance work done on the RV like oil changes, chassis lubrication, coolant flushes, and so on. These are considered part of the normal maintenance and wear and tear that the RV owner is responsible for.

As for what is covered, that can be very different from one contract to another. Some extended warranties are very comprehensive and will cover almost everything that could fail on your RV.

This can include the engine and drivetrain, leveling jacks, air conditioners, refrigerators, and much more. Obviously, the more risk the warranty company has, the more you will pay for a comprehensive contract like that.

Other extended warranties are targeted only for the most expensive parts of the RV. Usually these contracts focus on the engine and drivetrain mainly because that is where big dollar repairs could happen.

For those who can afford to pay for most RV repairs on their own this could be a good choice. This is because it transfers the risk of only the really high dollar repairs to the warranty company while keeping the overall warranty costs low.

Also, extended warranties are designed to pay not only for the parts of the covered repair, but also the labor as well.

What About Filing A Claim?

If you have a claim, there will be a process to go through to get approval for the repair. But most warranty companies try to make this process as easy as they can.

Keep in mind though that some people try to scam the warranty company to pay for RV repairs that are not really covered by their contract. So if they seem to be overly careful in the approval process, just be patient. Most of the time, you will be rewarded with a covered repair soon enough.

Where Can You Get An Extended Warranty?

If you buy an RV from a dealer, you may be able to get an extended warranty on your rig through them. But it doesn’t hurt to shop online and see what is available to you as well.

And if you buy your RV from a private party you will have to use an online warranty company. I do not specifically recommend a particular company myself. I think it’s a good idea to research each company that you are considering.

A good place to start is online RV forums. Also look for online reviews on each company. Keep in mind that people who have a beef with the warranty company will be very vocal.

And they are many times more likely to air their views online than those who had a pleasant experience. Just factor that in to your research and consideration.

The last thing I can say about RV extended warranties is that I own a contract on our diesel pusher motorhome. So obviously, I feel that they can be very useful.

On the other hand, I don’t think that everyone should have an extended warranty on their rig. Consider, how much risk of possible repair costs you are willing to shoulder yourself first.

Then determine what your budget will allow for the extended warranty cost itself. Using those two parameters, you should be able to find an RV extended warranty that works for your particular situation. Or you may find that it is not even needed in your case.

Enjoy your research, and have safe and happy travels my friends!

A 50 Amp To 30 Amp Adapter – Is It Safe?

In a previous blog post I discussed the possibility of needing to adapt a 30 amp campground service to a 50 amp RV. This is a very common scenario in many campgrounds. A less common scenario is just the opposite. That’s when you need to run a 30 amp RV from a 50 amp campground pedestal. So can you use a 50 amp to 30 amp adapter safely in this case?

Disclosure: Please note this post may contain affiliate links. This means – at no additional cost to you – I earn a commission if you make a purchase using our affiliate links. I only link to products and companies I use and feel comfortable recommending. The income goes toward supporting the free content on this website.

Why Is An Adapter Needed?

There are a lot of RVs on the road that are wired for a 30 amp electrical service. To understand what this means, it’s good to have a mental picture of what an amp is. And while we are at it let’s also do the same for volts too.

The best analogy I have heard to describe the relationship between amps and volts is to picture a water hose. There are different sizes of water hoses, some big, some small.

For instance, a garden hose will put out a steady stream of water. But a fire hose is much larger and therefore will put out a lot more water at the end.

Volts are like the water pressure that goes into the hose. There has to be some water pressure to move the water along.

But if you have a consistent water pressure, the fire hose will move more water than a garden hose. So in RVs a 30 amp service is like the garden hose. It moves electricity along to the appliances in the RV.

But a 50 amp RV service can move a lot more electricity at the same time because the wiring is much larger and more capable.

The volts at the campground pedestal should remain at 120 volts no matter what RV is plugged into it. So we can determine how much difference there is in consumable power between 30 amps and 50 amps by using a common electrical formula.

It says that you multiply the amps times the total volts. Then you will know the maximum simultaneous power capability of any electrical system (the watts).

So if we multiply 30 amps times 120 volts, a 30 amp RV can consume 3600 watts of power at one time. But a 50 amp RV has two legs of service going into the rig instead of just one.

So if you add the two lines of 120 volts, that is a total of 240 volts. Then multiply that by 50 amps for each line and you have 12,000 watts of consumable power at one time.

Clearly then, a 50 amp RV uses a lot more power than a 30 amp RV. So what happens if you use a 50 amp to 30 amp adapter for your 30 amp RV?

How Does A 50 Amp To 30 Amp Adapter Work?

Since a 30 amp RV has wiring that can only safely handle 30 amps of power, you don’t want to overload it. If you were to somehow plug the 30 amp RV service into the 50 amp campground pedestal without an adapter, it could easily overload.

So there is a need to step down the power of the 50 amp campground pedestal to the 30 amp RV service.

That is where the adapter comes in. It does that work for you. Even though there is a lot more electrical power available at the pedestal, it restricts the total output.

That means that it steps it down to the usable 30 amps of power that will not harm your RV or your devices. Think of it as an adapter at the end of the fire hose that steps down the water stream to the size of a garden hose.

What does All Of This Mean For Your 30 Amp RV?

So what does this mean in terms of what you usually do with your RV? Does this adapter change the way you use your appliances or devices? Not really.

Since you still have the full 30 amps of power that you always use, nothing will change when you plug into a 50 amp service with an adapter. RVs with a 50 amp service that plug into a 30 amp receptacle will have to make changes in their power usage.

But not those who have a 30 amp RV and plug into a 50 amp pedestal. You don’t get any additional power , but you don’t lose any power either.

I hope this helps you understand how RV electrical services work and how adapters help in special situations. Let us know if you have had any interesting experiences with 50 amp to 30 amp adapters in the comments below.
