Choosing the Best RV Water Pressure Regulators 2019


Traveling in an RV gives you the opportunity to see the world in a more exciting and adventurous light. It lets you see the outdoors for what it really is. If you are a regular RV traveler, then you should know that your vehicle is designed in such a way that it can accommodate a specific pressure of water.

That said, pressurizing your water system for more than what it can accommodate might cause several issues, like burst pipes, compromised appliances within your rig, and leaky fittings. Those are the things that you never want to happen in your RV. It should also be noted that city water pressure differs from one location to another.

With that in mind, it would be best for you to invest in the best RV water pressure regulator so you can prevent any possible damage to your components, seals, and connections within your freshwater system.

What Makes an RV Water Pressure Regulator Essential?


A water pressure regulator is a great device to add to your rig considering the fact that it is a big help in making all your trips memorable. With the aid of this regulator, you can take full control of your indoor water lines, making it possible for you to take a shower, wash your dishes, or get a good supply of water for various reasons without any issues.

So now the question is why an RV water pressure regulator is really essential. A viable answer is that the majority of water lines in a recreational vehicle are primarily designed to accommodate around 100 psi. A lot of RV parks offer water pressure, which is low enough that you no longer need to invest or use a regulator.

However, plenty of these parks also have extremely high water pressure that might cause your RV water lines to burst. Such issue can be damaging to your RV as it can trigger a leak, especially if you are parking in an enclosed area.

Such will cause flooding in your RV and can trigger permanent damage to your cabinets, storage bins, walls, and floors. One way to solve that problem is to invest in the best water pressure regulator for RV. The five products mentioned here are among the most recommended regulators in the market today known for their effectiveness.

1. Camco RV Inline Water Pressure Regulator

If you are in search of an inline water pressure regulator designed for your RV, then this product from Camco is definitely an excellent choice for you. What’s good about this water pressure regulator is that it is designed in such a way that it can offer protection to the plumbing system and hoses of your RV.

That said, expect it to be a big help in preventing damage to the plumbing and hoses, which is often caused by city water with an extremely high pressure. This water pressure regulator from Camco can be expected to work in a way that it can reduce the pressure to a consistent and safe 40-50 lbs.

It is also a big help in protecting the equipment and preventing the risk of hose failure, thereby prolonging the life of your equipment. Another advantage of this water pressure regulator is that it can easily attach to garden hose threads that are around ¾ inches. It is made of a solid and durable brass material.

The fact that it is made of brass is also a big advantage as it can make your drinking water safe considering the fact that the material is free of lead and corrosion. I find it really suitable for RVs as it can regulate the pressure down to what your vehicle really needs.

However, there is a minor issue with leaks but you might be able to solve that with the help of a Teflon tape.

Such is enough to protect the water hose and equipment in your RV from damage often triggered by high city water pressure.

Another great thing about this regulator is that it is known for its high flow. You can expect it to provide an additional of 15 to 20 percent water flow. I find the built-in water gauge in this product useful, too. Such gauge is easy to read as it shows the regulated pressure.

The gauge features a yellow zone, which indicates water pressure of lower than 40 psi. It also has a red zone, which shows more than 50 psi of pressure. Such makes it possible for you to keep track of everything. Another possible advantage of this regulator is its ability to connect easily to a ¾-inch garden hose thread.

Constructed from highly durable brass, I think that this water pressure regulator will also be able to stand the test of time. It is sturdy and can resist all harmful elements that might damage it, including lead and corrosion.

One minor problem, though, is that its cover is made of plastic, which is not that durable.

Lead-free due to the special double casting process and treated to effectively prevent growth of bacteria, you can trust that this valve will keep you and your family safe and healthy.

RV Water Pressure Regulator Questions and Buyer's Guide

the Best RV Water Pressure Regulators

Searching for the best RV water pressure regulator reviews might cause you to be introduced to numerous options. With the numerous options claiming to be the best, you may get confused all throughout the selection process. If that is the case, then you should consider basing your decision with the help of these factors:


Take note that there are different types of water pressure regulators designed for RVs today. That’s why you really have to spend time researching about your options and figure out which type is compatible with your vehicle and its water system.

One of the types of RV water pressure regulators is the in-line barrel type. Many RV owners actually prefer this type considering the fact that it is inexpensive. It is also designed in a way that it can restrict around 40-45 psi of water pressure.

One thing you have to take note of about the in-line barrel regular is that it does not permit you to make adjustments on water pressure. Furthermore, it does not only reduce city water pressure but also restricts the water flow. The result is weaker flow in the shower as well as in your kitchen and bathroom sinks.

Another type that you can choose is the in-line barrel high flow RV water pressure regulator. It is more expensive than the previous one but it is a great choice because of its high flow rate, resulting in a better water flow in the sink and shower.

However, take note that just like the previous type, it does not also let you make adjustments to pressure. The last type that I would like to recommend is the adjustable water pressure regulator. This type often features a gauge and is the most expensive out of the three.

Despite its high price, many still consider buying this type because of its numerous benefits. One is that it is adjustable, meaning you can make changes to the water pressure based on your needs. Furthermore, you are allowed to utilize more than one adjustable regulators for various parts of your vehicle, including the shower and sinks.

Water Pressure Gauge - How to Use RV Water Pressure Regulator?

It is also advisable to assess the water pressure gauge of the regulator prior to buying. It should be enough to meet your specific needs. A wise recommendation is to go for a regulator, which can control up to 50 psi of water pressure.

It should be noted that while the regulator is only a small device, you can expect it to be really useful in keeping the psi of water penetrating your RV to a safe level. Most recreational vehicles today actually have plumbing systems that can handle 100 psi.

However, it is still recommended to stick to regulators that can handle a max of 50 psi if your vehicle is an old model. If your RV is newer, then the recommended water pressure for RV should be at 60 psi.


Another factor that you should check out is the material used in manufacturing the regulator. The most recommended one is actually brass. In fact, most of the water pressure regulators for RVs today are made of this material. It is known for being sturdy, solid, and resistant to harsh elements.

Before buying, though, make sure that you really spend time assessing the quality of the materials used. It should be able to last for a long time. Go for one, which is heavy-duty and can resist elements, like lead, rust, and corrosion. It should be made in a way that corrosion and water contamination can be prevented.


Compare the prices of different water pressure regulators, too. When comparing prices, do not forget to assess the individual features, pros, and cons of each product that you thinking of buying. That way, you can find a water pressure regulator for your RV, which is offered at a reasonable price without skimping on quality.

Once you have already made your choice, you have to make it a point to check the condition of the regulator from time to time. Note that just like other valves and fixtures in a plumbing system, your RV water pressure regulator will also perform badly after some time, especially if you have already used it for a long time.

Be aware of the different signs that indicate that the regulator is no longer working the way it is supposed to. Among these signs are any kind of water hammering, significant increase or decrease in water pressure, and other water pressure inconsistencies.

If you experience those issues, then make it a point to use a gauge to test the water pressure, especially if you are worried about the effectiveness of the regulator. A wise tip is to test the water pressure each year. Doing it once a year is the best thing to do.

Remember that extreme water pressure has the tendency of putting more strain into your RV’s plumbing system. It might trigger your dripping faucets, running toilets, water hammers that might affect the walls of your RV, and a burst pipe that will eventually lead to flooding.

Testing the water pressure and the condition of the installed regular is, therefore, necessary to ensure that you will be able to fix any impending problems that might negatively affect the entire water system of your recreational vehicle.

Final Words

Investing in any of the best RV water pressure regulators today is the key to enjoying an excellent supply of water while you are traveling in your vehicle. You will enjoy just the right amount of flow and pressure, making your life in the RV even more convenient and enjoyable.

In this case, it would be best to look for a water pressure regulator, which is guaranteed to protect the plumbing system of your RV while also supplying a consistent and continuous flow of water into your showers and sinks.
