I found myself intrigued by the two-layer inlet screened filter, as well. It’s vital for its ability to keep large particles out of my water supply. As a result, I don’t have to concern myself with gravel or other debris causing issues inside the RV’s plumbing.

RV Water Pressure Regulator Buyer’s Guide

All the information provided below will be essential in helping you figure out which RV water pressure regulator is the best for your needs. It’ll turn this otherwise overwhelming experience into something that’s relatively simple.


In other words, the knowledge you’ll learn below will offer you a basis of crucial information you can rely on during your search. It’ll hopefully act as your guide and help you make an informed decision about which regulator to buy.

Things to know before buying an RV water pressure regulator

There will be a multitude of factors that’ll shape your decision about which product is the top-rated water pressure regulator for RV. And in this section, we’ll discuss these factors to help make this process as painless as possible.

Each one of the following qualities below will help determine whether or not an RV water pressure regulator is high-quality or not. Having a grasp of all of these factors will make your search a less time consuming and frustrating experience.


The first thing you should be aware of when searching for an RV water pressure regulator is what material was used in creating the product. In most cases, it will be some sort of brass, which is a solid, durable option that’s resistant to different types of elements.

There are regulators made from other materials, but manufacturers tend to stick with brass because of its consistent performance. However, you must make sure the model you choose is made from a material that’s proven to offer quality endurance and resistance.

If you don’t, you could be on Amazon again in a few months searching for another water pressure regulator. With this in mind, I’d recommend going with the products that have a heavy-duty design, which will be more resistant to corrosion and other elements.

In the end, a high-quality water pressure regulator will be built in a way that makes it less vulnerable to any contaminants. After all, you never know what could be lurking in the city water at your favorite campground.


As we’ve discussed previously, there are three primary types of RV water pressure regulators, and each one has its own set of benefits. Therefore, you must decide which one matches your needs the best.

For instance, if you’re looking for an inexpensive model that will do the job at a bargain price, an inline barrel regulator might be a worthwhile option for you to consider. It’ll keep the water coming into your RV at a pressure of 40 to 4 psi, but won’t offer you any control over the experience.

It also affects the flow rate of your showers and sinks around your RV, which can be quite annoying. If you’re more inclined by a regulator that doesn’t affect the flow rate of your RV’s water components and is still relatively inexpensive, an inline barrel high flow regulator would be more your speed.

The high flow addition to the inline barrel allows for your showers and sink to operate at a reasonable rate. But it still doesn’t allow any control over the how it works. In other words, it’s not adjustable.

And if you want the ability to adjust the water pressure regulator, you’ll be stuck forking over extra cash for an adjustable regulator. These products will allow you to change the water pressure, so it matches your preference.

Given all this information, you can see that there’s a decision to be made here about what you precisely want out of your new RV water pressure regulator.

For me personally, I’d opt for the adjustable regulator over the other models because I like thought of setting it up according to my preferences.


Figuring out your budget is an essential step in finding the perfect RV water pressure regulator. Honestly, it’s a significant piece to the process of buying any product. The key is finding a high-quality product that isn’t too cheap or expensive.

But preferably one that lies comfortably inside your budget. If you don’t, you’ll end up resenting the purchase you’ve made. And that’s the last thing you’ll want to happen. As a result, you should thoroughly compare the models you’re considering to their competitors.

When comparing the products, you’ll want to look at the features, pros/cons, and overall productivity of the model itself. It’ll make sure you’ll be able to determine the reason why one regulator costs more than another; then, you can decide whether or not that reason is worth the higher price.

In doing so, you’ll be ensuring you make a cost-effective decision that won’t fill you with regret later. It’ll allow you to buy a regulator at a reasonable price that’s within your budget without sacrificing the overall quality of the product.

The Regulated Pressure

In most cases, RVs have water systems that are designed to handle a maximum pressure of 100 psi. But campgrounds allow their water pressure to push past this range and some even reach 150 psi.

As you might expect, this elevated amount of pressure can have a severe impact on your RVs water system without a high-quality regulator. And since these campgrounds allow their water pressure to hover around 150 psi, I’d recommend getting a regulator that can maintain the pressure at 50 psi.

In a perfect situation, the water pressure inside your RV should stay between 40 and 60 psi. Keeping it inside this range will ensure nothing funky happens such as leaks, pipes bursting, or flooding.

Due to this, it’s in your best interest that you don’t take any unnecessary risks with the water pressure inside your RV. If you do, the cost of the repairs to fix flood damage inside your RV could end up costing you a significant amount of money.

Customer Reviews

There isn’t a better resource available to you than other customer’s experience with the products you’re considering. And these customer reviews will give you access to different customers feelings on a product.

You’d be shocked how many people buy a product before reading at least a couple of customer reviews. They see the 5-star rating and think that there’s no need to keep researching as it seems everyone was satisfied with their purchase.

But what these people fail to understand is some companies inflate their ratings by creating fake accounts. As a result, it’s in your best interest to scroll down toward the customer review section and take a gander.

After all, someone else’s terrible experience might save you from buying a dud. So please, take advantage of this resource and make it a critical factor in your final decision. If you do, I promise you’ll end up with an RV water pressure regulator that you’re happy with owning.

Understanding these five factors is a pivotal step in finding the best RV water pressure regulator for you. And once you make some decisions regarding these five factors, the overwhelming sea of products will start to reduce into a more manageable amount of options.

What are the different types of RV water pressure regulators?

If you’re going to make a responsible purchase of an RV water pressure regulator, there are three different types that you’ll need to be aware of: inline barrel RV water pressure regulators, inline barrel high-flow RV water pressure regulators, and adjustable RV water pressure regulators.

Since there are different types, you’ll have to spend some time going over which one fits your particular needs the best. And we’ll try to make this process easier by discussing the basics of each type below.

Inline Barrel RV Water Pressure Regulators

An inline barrel RV water pressure regulator is typically the cheapest type available on the RV water pressure regulator market. These particular models are designed to restrict water flow and keep the incoming water pressure down to a safe 40 to 45 psi.

If you’re looking for a bargain, high-quality inline barrier regulators will do the job its design to do. However, they’re generally rudimentary products that don’t offer much of anything feature wise.

In other words, you won’t be able to adjust the water pressure. It’ll also restrict water flow, which will slow down the flow of your showers and sinks around your RV resulting in less optimal water pressure in those situations.

With all this in mind, I’d recommend spending a little extra and investing in one of the other two types. But if you’re in a real bind, these inline barrier regulators will ensure you don’t have any issues with high-pressured water coming into your RV’s pipes.

Inline Barrel High Flow RV Water Pressure Regulators

An inline barrel high flow RV water pressure regulator tends to be more expensive than an regular inline barrel one, but it fixes the main issue that exists with those types. See, these allow for a high flow rate, which results in better water flow in both your showers and sinks.

However, these still don’t allow you to adjust the water pressure yourself. As it happens, the incoming water will be regulated to the safe range of 40 to 45 psi that you would see with a regular inline barrel regulator.

Due to fixing flow rate issue, I’d recommend getting this particular type of regulator over a regular inline barrier model. It doesn’t cost that much more and will ensure your water components inside your RV such as your shower or sink will work effectively.

After all, there’s little in this world that’s worse than using a shower with a low flow rate. It’s just a miserable nightmare that nobody wants to experience, especially during their RVing trips.

So, if you’re looking for an inexpensive option, do yourself a favor and spend a little extra on an inline barrel high flow regulator. You won’t regret it.

Adjustable RV Water Pressure Regulators

These are the most expensive regulators on the RV water pressure regulator market. The primary reason for their higher-price is they feature a gauge and allow you to adjust the water pressure around your preferences.

Hence, the name adjustable RV water pressure regulator. With this feature, it becomes quite apparent that these products are worth the increase in price. I mean, it gives you total control over the water coming into your RV.

And given the iffy water sources at campgrounds, this sense of control can be a welcome comfort. These adjustable regulators also allow you to use more than one at a time, which means you can adjust the sink’s water pressure to a different psi than your shower.

Due to this, it’s quite obvious these adjustable regulators are the best of the bunch. And often, people don’t mind paying the additional price because of the convenience these models offer the person who’s lucky enough to buy them.

As a result, if you can afford one, there should be no reason you opt for the other two types over the adjustable water pressure regulators. It just doesn’t make logical or practical sense given the amount of control these products can offer you.

How to install RV water pressure regulators?

The process to install most RV water pressure regulators is quick and easy. In fact, the entire installation shouldn’t take much longer than a few minutes. All you have to do is follow that pesky instruction manual that’ll undoubtedly come with the regulator.

I know, following an instruction manual sounds like a painful experience. But since these products drastically differ from model to model, talking about installing one in general terms is borderline impossible.

If your instruction manual seems overly complicated, which does tend to happen, you can always search through YouTube for a video showcasing the installation process. As an example, this particular video demonstrates how to install a Camco regulator.

And if all these methods fail, you can always call the manufacturer themselves. In most cases, there will be a customer service representative ready to help you through the entire process. I know, it’s shocking to hear that a customer service employee was actually helpful, but with products like these, they can be a godsend.

But honestly, if you buy from one of the brands mentioned in this article, the instruction manual should be simple enough to follow.

How to use an RV water pressure regulator?

To get the best results out of your RV water pressure regulator, it’s best you follow the directions laid out in the instruction manual. I know, I probably sound like a broken record talking about the manual. But it does have all the necessary information that’ll ensure your regulator operates at peak performance.

However, the overall process of using an RV water pressure regulator isn’t all that complicated to begin with; you install it using manufacturer’s specifications and depending on the model adjust it to your particular preferences.

Once it’s connected to your water supply, all you have to do is sit back and let it do its job.

RV Water Pressure Regulator FAQs

What is an RV water pressure regulator?

An RV water pressure regulator is a device that keeps your RV’s water system working safely and appropriately. It does so by taking control of your RV’s water lines and keeping the psi of the water coming into your RV at a level that won’t cause any issues.

After all, you never know when a campground’s water pressure will be incredibly high, which makes these products an essential piece of the RVing experience. And if this high-pressured water comes into your RV’s unchecked by a regulator, it can do a lot of damage to your plumbing system.

It could cause your RV water lines to burst, which can trigger a leak and make your RVing experience a living nightmare. It might even end up flooding your RV; this nightmare circumstance can cause permanent interior damage to things like your floors, cabinets, walls, and other stuff inside your RV.

Interior repairs can cost you a truckload of money and paying a small amount for a regulator now could save you from paying this expense later. Honestly, with the best RV water regulator, these types of issues will never become a part of your RVing experience.

As a result, these RV water pressure regulators become a must-have item for any RV owner. I mean, it’s always better to be safe than sorry when it comes protecting your RV against awful things like flooding.

How can I make my water pressure stronger?

My first suggestion would be to replace your regulator with a high-quality one. Any of the options mentioned within our article should work well. But in particular, I’d take a strong look at AECOJOY’s Adjustable Water Pressure Regulator.

For example, this model offers impressive adjustability between 0 to 160 psi. So it shouldn’t be too difficult to find a pressure rate suitable for our needs. I find anywhere between 50 and 60 psi a perfect comfort level for camper usage.

Aside from buying a new regulator, you can try adjusting your old one. First, you’ll need to go to your water supply line and turn the conical valve’s bolt clockwise while paying attention to its gauge.

Then, make sure the pressure reaches a level fit for your water preferences.

What is maximum water pressure for RV?

In most cases, your motorhome’s water pressure will max out at 125 psi. But I’d recommend refraining from staying with that setting. Honestly, it’s just a waste of water and won’t make your shower much more comfortable.

You’d be better off adjusting the psi to a rate between 55 and 65 psi. Most rig owners find any flow rate within this range sufficient. I certainly haven’t had any complaints from guests or family members using my RV’s shower.

Pressure reducing valve vs pressure regulator: What is the difference?

RV owners will encounter pressure-reducing valves and pressure regulators when trying to solve their water flow issues. As a result, it’s common to wonder what’s the difference between the two devices.

It boils down to how they function when the water isn’t flowing. For instance, a pressure-reducing valve continues to do its job and control pressure. It provides more control over your rig’s plumbing system than you might expect from these devices.

Meanwhile, most water pressure regulators don’t offer the same ability. These devices only work when water flows from your faucet or shower. So it ends up being a slight difference that can be a vital buying factor for some shoppers.

How long does a water pressure regulator last?

A water pressure regulator for home or camper use must provide a certain durability level. Otherwise, these devices won’t give buyers the performance necessary to work effectively.

Most manufacturers ensure their camping water pressure regulator can last 10-15 years.

In fact, many high-quality ones can last up to 15 years without issue. I could easily imagine Camco’s RV Brass Inline Water Pressure Regulator meeting this expectation. Its robust construction has proven to be durable and trustworthy.

How does it work?

As mentioned before, an RV water pressure regulator works by giving you more control over the water that comes into your RV. In other words, you’ll be able to control both the flow and the pressure of the water coming from the water source that you’re using.

Even with the lowest-quality options, an RV water pressure regulator will work by lessening the incoming water pressure to a safe, reasonable level. It does this by limiting the water coming into your RV to a constant set pressure.

It keeps this constant set pressure by activating when the water enters through the regulator’s inlet end and close to the flow area’s fixed seat. From there, the incoming water will move into a cylinder that’s attached to a larger diaphragm, which is near the end of the outlet.

The water’s pressure will then put its full brunt on your water pressure regulator’s diaphragm. In response, it’ll close just enough that’ll it will reduce the pressure and flow to your safe, set rate.

I know, it sounds overly complicated. But the gist is that these products will ensure your RV doesn’t fall victim to flooding by regulating the water coming from the source you’re using. And it’s something you should at least think about getting because the water pressure at campgrounds is always a little unpredictable.

What are the most trusted RV water pressure regulator brands?

All the brands mentioned in our product review section are considered top-notch manufacturers of RV water pressure regulators. But the following three brands are the ones that I’ve found to provide their customers with the best buying experiences: Camco, Renator, and Valterra.

And since I’ve always found it more comforting to buy from a company I felt familiar with; I thought I’d offer you some background information on each of these fantastic companies. It’ll give a sense of what you should be looking for in a high-quality water pressure regulator manufacturer.


Regardless of the RV part you need, Camco will be a high-quality manufacturer of the product. In fact, this company has been a leader in the RV part marketplace for well over five decades. They’ve cultivated this success in this massive industry through always “meeting the ever changing demands of a challenging marketplace.”


Renator is a manufacturer headed by a founder who started his company out of sheer convenience after “realizing that there weren’t many long lasting and reliable water regulators out there at an affordable price.”

Therefore, you can feel comfortable knowing the person overseeing the creation of the water pressure regulator you’re considering has been in your shoes before. It’s quite a comforting feeling knowing a manufacturer thinks and feels the way you do.


Valterra has been in the RV, pool & spa, and plumbing industries since 1981. And from the day their manufacturing started, they’ve strived “to reduce costs and improve the bottom line.” As a customer, there isn’t much more I could ask for from a manufacturer.

In the end, you’d be in good hands buying from any of these three brands. In fact, you’d be well-suited buying from any of the brands mentioned in the product review section. All of them are more than capable of providing you with a top-notch regulator.

How to increase water pressure in an RV?

Increasing your water pressure inside your RV isn’t a good idea. Most RV manufacturers suggest keeping your water pressure from exceeding 40 to 50 psi. If it gets higher than this psi, you’re at risk for pipes bursting, leaks, and flooding.

But if you do have issues with water coming out of your shower and sink slow, it might be a problem with water flow rather than the pressure. And there are ways you can increase the flow that’ll keep your RV from any dangerous situation.

The first thing you’ll want to do is check the water fixtures inside your RV and check for water flow restrictors. If you find one after unscrewing your showerhead or faucets, remove it, and your water flow should increase.

And if that doesn’t work or isn’t the issue, you should then check the type of RV water filter you’re using. It might turn out you’re using a smaller water filter, which are known to restrict the overall water flow inside an RV.

Where to buy?

The best place to buy an RV water pressure regulator is online through Amazon. The site will give you all the great deals and provide you with a variety of different options to look through. At this point, there isn’t an alternative that matches the quality of the buying experience that Amazon offers.

It’ll also give you an inside look into how other people felt about their experience with each product through customer reviews. In every regard, Amazon is the best place to shop for a new RV water pressure regulator.

But if you don’t like using Amazon, you have other quality options available to you. For instance, you can always adventure out to your local Lowe’s, Home Depot, or Walmart and see their selection. It’ll most likely be somewhat limited, but each store should have a few high-quality models.

You could even go to their main online sites and see the selection they have on there. It’ll most likely be more diverse than you’d see at the local store. Honestly, it seems like online shopping is the way to go these days in every capacity.

A site like Camping World might be worth a look as well. It should have few regulators itself for you to look through. You should use a site like this to compare prices with Amazon’s that way you can ensure you’re getting the best deal possible.

In the end, the great deals will often be waiting for you at Amazon. But it never hurts to look around as there are plenty of stores or sites that sell these products. So do a little research before solely relying on Amazon, just in case, some deal pops up out nowhere on another website or store.


Given all this information, determining the best RV water pressure regulator should now be a breeze for you. I mean, once you figure out what you need out of this product, picking one to buy becomes a rather simple process.

And after you make a final decision, you’ll have a high-quality at your disposal to ensure those pesky campground water sources never cause your RV any problems. You’ll never have to worry about leaks, pipes bursting, or floods.

Instead, you can sit back and relax as your regulator washes those worries away by keeping the water pressure at a safe range. So please, use all the information in this article to your advantage and make this process as simple as possible.

It’ll let you get back to the things that matter, like having fun or spending time with your family, that much quicker!
