Buyer’s Guide

Now for the buyer's guide. Here you'll learn all the necessary info there is to know before buying a water pressure regulator for your RV. And we've included a video and step-by-step guide on how to install one. Happy reading!

How to Choose an RV Water Pressure Regulator

Like we said, your RV has a maximum amount of water pressure it can handle and sometimes, while parked in campsites and using their services, the water pressure can go higher than the recommended amount, causing some unnecessary damage. There are a few features you should take into consideration when buying a water pressure regulator, such as the connector size, the material used, and the water pressure gauge.

Connector Size

Most RV water pressure regulators will use the standard ¾" connector size, meaning that it won’t be hard to connect anywhere throughout your plumbing system. However, there are some on the market that have a ½" connector size, meaning you need to check your RV manual to find the regulator that will fit. It would be a rare thing to find any threaded head to be a ½" connector, as most are the standard ¾" size.


The material used for your water pressure regulator is essential. Most manufacturers will use either lead-free steel or brass. The material is essential because it can affect how safe your drinking water is. These materials are also durable and robust meaning they’ll rarely crack. If you can’t afford these materials, some products are made from ABS plastic which is just a high-grade plastic.

Water Pressure Gauge

The water pressure gauge is the part of the regulator that allows you to view the PSI level. It’s recommended to find a gauge that can measure up to 50 PSI. However, some gauges can go up to 100 PSI. An important thing to remember is that you should be able to read the gauge easily. You will find products without a pressure gauge, these aren’t usually worth buying as you’ll most likely invest in a gauge further down the line. So to save yourself the effort and for best results, go for one with the gauge already attached.

Benefits of Investing in a Great RV Water Pressure Regulator

There are a few benefits to buying a great water pressure regulator. Benefits including, knowing that your drinking water is safe. Purchasing one of these could run the risk of diluting your water with chemicals, such as lead that leech from the brass or steel. Many regulators now come lead-free. You should never use any regulator that runs the risk of diluting your drinking water with lead. This can cause some severe health problems if used over a series of months.

Another benefit is that it it will save you a lot of money in the long run. If you don’t have a decent regulator, this could significantly impact your entire water system. By using a campsite, the water pressure is often higher than what your RV can handle, therefore you run the risk of bursting your pipes. No one wants to ruin their pipes, especially those of a brand new RV. You’d be surprised at how fast water pressure can destroy your system and ultimately end up in costly repairs.

Traveling in your RV and knowing that your system is working to its best ability is one of the most significant benefits of having a regulator. Knowing that your regulator can keep out gravel and large particles that can damage your pipes gives you peace of mind that your water will come out without any hindrance.

What is an RV Water Pressure Regulator? 

If you use your RV to travel frequently, you would know that water sources at different campsites and rest stops tend to vary. Different water sources bring unpredictable water pressures that can cause serious damage to the RV’s plumbing and the fixtures. 

A water pressure regulator helps guarantee an even water flow. It lowers the water pressure in the pipes by taking the high-pressure water of 150 psi and reducing it to around 50 to 80 psi.

How Does a Water Pressure Regulator Work?

A water pressure regulator reduces the speed at which the water passes through the pipe. This helps in ensuring that the pipes will suffer less wear and tear due to the water pressure. 

Moreover, the joints and fittings often get exposed to extreme pressures, which results in the loosening up or leaking. A water pressure regulator reduces the water pressure in the line present inside the valve. It features an adjustable spring-loaded diaphragm that allows it to do so. The water becomes constricted and is released at a lower pressure. 

Without this regulator, there is a high risk that the strong water pressure will blast through your onboard fixtures and appliances. This small device helps ensure that the psi of the water entering your RV stays at a safe level.

Adjustable vs. Non-Adjustable Water Pressure Regulator For RV - Comparison Overview 

If you’re thinking of buying an RV water pressure regulator, you should know that there are different types available. They mainly fall under two headings; adjustable and non-adjustable. So before you decide to buy yourself one, you must understand the difference between the two so that you can see which one suits your needs the best. 

Water Pressure Adjustment

Adjustable regulators feature a gauge that allows you to adjust the water pressure according to your preference, hence the name. With this feature, you get total control over the water entering your RV’s water system. Moreover, you can use more than one of these at the same time, which means that you can adjust your sink and shower’s water pressure to different psi levels.

On the other hand, non-adjustable water pressure regulators include are designed to help restrict the water flow and keep the pressure down to 40 to 45 psi. However, you can't adjust the water pressure using this unit. This means that you will have to experience less optimal water pressure while you shower. 


Adjustable RV water pressure regulators are more expensive as compared to non-adjustable units.

How to Install a Water Pressure Regulator on an RV

When you arrive at your location, you usually are unaware of how high the water pressure is at the campground. To help protect your RV drinking water hose and the plumbing system, we recommend that you always use a water regulator. It is really important to regulate the water pressure going into your RV. However, if you have any concerns about the water flow, especially with the shower, then what you need is an adjustable water regulator. 

Once you have your desired unit, you need to follow these steps. 

  1. On arriving at the campground, connect the adjustable water pressure regulator to the water supply. 

  2. Then connect the end of your drinking water hose to the regulator to help regulate the pressure before it enters the hose. 

  3. Most adjustable regulators are factory preset at 45 psi; however, if you think that the pressure is too low, especially in the shower, then take a flathead screwdriver and turn the screw to allow more water to flow into the RV. Do bear in mind that settings above 60 psi are not recommended. 

Now, if you’re still confused on how and what you should be doing, here is a link to a video that you can watch to solve all of your queries. 

Types of RV Water Pressure Regulators

Here are a few different types of water pressure regulators commonly used in RVs:

Inline Barrel

The benefit of this regulator is that it is usually at an affordable price and will restrict water pressure to a healthy 45 PSI. The only downside to using this regulator is that it doesn’t allow you to adjust the water pressure.

High-Flow Inline Barrel

These models can be more expensive, which is a downside until you learn that they provide a higher flow rate, meaning you can live as if you were at home. No one wants to have a poor water-pressure in the shower. These regulators also can’t be adjusted.


Certain regulators can be adjusted. These adjustable regulators come with a gauge that allows you to continuously monitor your PSI level. These are the most expensive out of the different types and you adjust the pressure or water flow simply by turning a screw.

People Also Ask

This section is to further help you understand these products, whether about what specific terms mean, to explain parts in more detail, or putting things in easier to understand language. We’ve collated some of the most asked questions regarding this topic and answered them the best we can.

How to Adjust an RV Water Pressure Regulator

To make adjustments to your water pressure regulator, you will need someone to assist you, so while you adjust the pressure, someone needs to test the water. Firstly, you will have to locate the regulator. Once found, then look for the external bolt. Loosen this locking nut and then turn the bolt. This will then allow you to adjust the water pressure. 

Turn the bolt either clockwise or counterclockwise, depending on what water pressure you need. For an increase in pressure, turn clockwise and for a decrease in pressure, turn counterclockwise. Make sure to keep track of the water pressure; once it is at 50 psi, then tighten the nut, and you’re good to go. 

What End of the Hose Does the RV Water Pressure Regulator Go On?

The best location for you to place your RV water pressure regulator is right between your water source and the freshwater hose. This way you know that the pressure of the water is correct before it enters the hose. Now all you have to do is twist the regulator onto the spigot and then connect the other end to the hose.

How Do I Know if My Water Pressure Regulator is Bad?

At times, you will experience some extreme RV water pressure regulator issues. When this happens, know that it's the regulator. A bad regulator will usually cause you to experience low or no water pressure in the RV; however, replacing it will solve the problem right away. 

However, some other factors could cause no or low water pressure; therefore, make sure to check them as well. See if the hose is clogged or kinked, if the water filter is dirty, or if the mesh or the regulator are clogged. 

How Much is an RV Water Pressure Regulator?

A water pressure regulator might be a small device; however, it can help protect you and your RV from major damage. Water surges can cause your water pipeline to burst, your RV’s water system to suffer, and can even cause damage to your fixtures and your appliances. Therefore, you must buy yourself a regulator that will help prevent all of this damage. 

Now the market is filled with different options, so which one should you opt for? You can find some units between the price range of $5 to $15. However, at this price point, you won’t get a gauge; these units often feature a pre-set psi and cannot be adjusted. 

Units that fall in the price range of $15 to $40 are lead-free and come with a pressure gauge, have a brass construction, and can be adjusted. Units that fall in the price range of over $40 can cost you as much as $100. However, these regulators feature a sturdy build and are very effective.  

How Much Water Pressure Should an RV Have?

As we described before, every RV can have different maximum or minimum PSI levels. You should always check this detail via your manual or when you buy the RV. However, the vast majority of newer RVs have a recommended level of 60 PSI.

However, newer models could probably survive at around 100 PSI. Older RVs are advised to stay at 50 PSI. There are regulators on the market that can reach up to 300 PSI. However, these aren’t needed for RVs.

Where is My Water Pressure Regulator?

If you want to adjust the water pressure, the first step you have to follow is to locate the water pressure regulator. This small device is usually located where your main water line is, right after the main shut-off valve. It is very easy to locate it in your RV. Moreover, it becomes easier for you to quickly shut down the main water line when you’re working or changing the regulator. 

Do I Need a Water Pressure Regulator?

No, you don’t need a water pressure regulator. However, it would be beneficial, as you can monitor and change your pressure and flow at any time, depending on the type you buy. If you want a somewhat seamless experience regarding your pipes and water, you should definitely buy one.

Regulators can also be useful in protecting your pipes from water and pressure surges. These are similar to an electrical power surge, in the sense that they will just overload your entire system to the breaking point.

How Long Does a Water Pressure Regulator Last?

It is standard practice to test your water pressure regulator at least every 12 months. Most high-quality regulators can last from three to five years. As long as the pressure doesn’t fall below the recommended pressure, your regulator will likely continue functioning for years.

How Do I Hook Up an RV Water Pressure Regulator?

It's as simple as screwing on the regulator to the piping or hose coming from the campsite. Most people like to connect it as close to where the water originates so it can regulate the water straight out of the source. If you put the regulator at the opposite end, this can result in damaged pipes or hoses as the water pressure builds up. 

RV Water Pressure Regulators - Look After Your Plumbing System

Hopefully, we helped answer many of the questions you had regarding your RV water pressure regulators. As you now have realized, there are many things to consider when purchasing any type of regulator.

There are plenty of variables, including what type of regulator it is, if it has a gauge, what is the maximum the PSI can reach before breaking, and even, if it will fit your hose or standard water supply.

We hope to have enlightened you a bit more on the importance of a water pressure regulator for RV living, and if you choose any of the above options, we're sure you'll be more than satisfied with your purchase.
