Best RV Water Pressure Regulator Reviews & Recommendations

The Renator M11-0660R Water Pressure Regulator Valve is our top pick for a number of reasons, including affordability and all of the benefits and features that we’ve outlined as “must-haves.” This adjustable water regulator comes with a gauge that can measure up to 160 PSI. It’s lead-free and contains oil to help minimize friction on the internal components, with an internal filter to help prevent rocks and debris from clogging your water lines. This RV water pressure regulator also comes with a one-year guarantee. It’s hassle-free and works seamlessly with both older and newer RV models. But most importantly, it’s easy to install and easy to adjust the pressure. 


While this RV water pressure regulator is one of the most popular, there have been cases where it stops working after a few months of use. A common concern is the gauge fails to accurately read the incoming pressure, which can lead to damage in your RV if you leave the hose unattended.


Product Specs

  • Material: Brass
  • Max PSI: 160 PSI
  • Extra Features: Gauge, internal filter, and adjustable screw

Pros

  • Made from lead-free, highly durable material
  • Backed by a one-year guarantee
  • Gauge makes it easy to read water pressure
  • Adjusting pressure is as easy as turning a screw

Cons

  • Can suddenly stop working in some instances
  • If gauge fails to read pressure correctly, potential damage might occur

You don’t always have to pay a lot of money to find a quality product that can protect your RV’s plumbing system and the Camco Brass Water Pressure Regulator with Gauge is impressively affordable. While it doesn’t display the precise PSI from the intake and isn’t adjustable, you do have a simple gauge that indicates safe, risky, and dangerous PSI levels based on whether the needle is in the green, yellow, or red zones, respectively. The RV regulator has a factory pre-set of 40 to 50 PSI, which is more than safe for older and newer RV models. The color-coded pressure gauge is a better bet for people who don’t know which PSI range is safest for their RV or don’t want to bother with a traditional gauge and numerical readings. The simple design also makes this a goof-proof option. 


However, a common issue with this RV water pressure regulator is the PSI can be inconsistent. Since it’s not adjustable, you have no control over the output, which in some cases can be as low as 20 PSI.


Product Specs

  • Material: Brass
  • Max PSI: 125 PSI
  • Extra Features: Color-coded gauge

Pros

  • Affordable price
  • Automatically lowers PSI to prevent damage
  • Color-coded gauge makes readings super simple
  • Safe for old and new RV models

Cons

  • PSI can be inconsistent
  • Doesn’t allow you to control the output

The RVAQUA M11-45PSI Water Pressure Regulator is moderately priced and adjustable, with the ability to manage flows as intense as 160 PSI. It’s constructed from durable brass, lead-free, and factory pre-set at 45 PSI. This RV water pressure regulator is also designed with built-in filtration to protect against blockage, and these features make it one of the best water pressure regulators you can buy. One of the best features is the company’s customer service. If you find yourself struggling to attach it or are having difficulty with the readings, the prompt support from the Kozyard parent company helps to correct any issues or send replacement parts if the gauge is faulty. Other benefits are the easy installation process and the sturdy construction.


A common issue with the RVAQUA regulator is its packaging. There have been instances in which the package arrived and the oil that lubricates and protects internal components leaked, making it inoperable. Another concern includes difficulty adjusting the pressure and getting the regulator to effectively maintain that pressure.


Product Specs

  • Material: Brass
  • Max PSI: 160 PSI
  • Extra Features: Built-in filter, gauge, and adjustable screw

Pros

  • Pre-set at 45 PSI for safe water flow
  • Easy installation
  • Durable and sturdy
  • Supported by great customer service

Cons

  • Packaging can lead to damage or oil leaks
  • Adjusting water pressure can be difficult, along with maintaining that adjusted pressure

The Kohree RV Water Pressure Regulator Valve is a completely lead-free RV water pressure regulator developed entirely out of brass. The device is rated and treated by hot casting it, which allows it to run more efficiently and save you money all while increasing its output ability. It’s built to attach to all water hose threads for versatility as well, and it’s easy to install and is also rather accurate. One of the best benefits? It contains oil to prevent friction so all the internal parts function properly and it’s adjustable up to 160 PSI too. Best of all, it’s explosion-proof, designed to withstand shock better, and has a dual-layer inlet screen filter that prevents blockages.


There have been complaints of the water regulator leaking, but this isn’t a consistent problem. The reported leaks may be to other faults like insufficient tightening and issues with the attached water spicket. Another issue is with the shipping and packaging. It may arrive damaged with a cracked screen and leaks.


Product Specs

  • Material: Brass
  • Max PSI: 160 PSI
  • Extra Features: Adjustable screw, gauge, and dual-layer filter

Pros

  • Durable hot-cast brass construction
  • Fits all U.S. water hose threads
  • Pre-lubricated to limit friction and wear
  • Adjustable up to 160 PSI

Cons

  • Improper fitment may cause leaks
  • Packaging can wind up allowing products to get damaged during shipping

The Valterra RV Hi-Flow Water Regulator is exactly what you need if you want to regulate high-pressure flows for a newer-model RV, as this device is designed to regulate the water pressure inside the RV to 50 to 55 PSI to better protect the tank and your ride. It’s easy to install too and connects directly to any standard faucet or hose fitting and the water regulator is available in two metals, brass and stainless steel. The brass option is rust-resistant, sturdy, and durable even after years of operation and stress. This certainly makes for a heck of a difference when it comes to shower water pressure too.


There have been issues with the device leaking when first connected and you may have to add a rubber washer ring to the regulator to prevent it from leaking. Another big letdown is the regulator does not come with a PSI gauge so you can’t see how much pressure is being used. It also may be difficult to remove from the attachment after you are done using it.


Product Specs

  • Material: Brass or stainless steel
  • Max PSI: 160 PSI
  • Extra Features: None

Pros

  • Automatically regulates pressure to 50 to 55 PSI
  • Two durable metal choices
  • Delivers a high flow rate despite lowering pressure
  • Connects to standard fittings

Cons

  • Will need a rubber washer added to prevent leaks
  • No PSI gauge
  • Can be difficult to remove

If you’re looking for an RV water pressure regulator that can survive different climates without causing worry, the Leisure Coachworks RV Water Pressure Regulator is a great choice. Able to operate without issue in temperatures as low as 14 degrees Fahrenheit and as high as 200 degrees, it’ll survive almost anything. Plus, it’s made out of durable brass with less than 0.13 percent lead to meet NSF lead-free requirements. Equipped with an easy-to-read gauge, this regulator will automatically set your flow at 45 PSI on its factory setting. However, all you have to do is twist the adjustable screw and you can control the pressure up to 160 PSI.


You will, however, want to keep an eye out for potential leaks with this RV water pressure regulator. If you don’t use a washer with this regulator, it can leak; faulty washers can also cause potential problems.


Product Specs

  • Material: Brass
  • Max PSI: 160 PSI
  • Extra Features: Adjustable screw and gauge

Pros

  • Factory setting keeps the pressure at 45 to 55 PSI
  • Easily adjusts higher if needed or desired
  • Can be used reliably in temperatures from 14 to 200 degrees
  • Lead-free construction

Cons

  • Will leak if not used with a washer
  • Faulty washers can also cause potential leaks

Camco is one of the best-known names in RV equipment, and that’s why it’s appearing again on our list. The Camco Plastic Water Pressure Regulator is a great alternative to traditional brass regulators, with a lightweight design that still offers good durability. It’s able to perform reliably without weighing you down, and it automatically reduces high water pressure to a level that’s safe for new or old RVs. This regulator is made from durable ABS plastic, and it helps limit damage to your RV hoses, pump, and internal plumbing lines by taking campground water pressure down to 40 to 50 PSI. Featuring 3/4-inch threads, it works with most hoses (including garden hoses) and helps keep your hoses working flawlessly without bursting or facing inconsistent pressure.


The only potential drawback of this RV water pressure regulator is plastic is inherently not as durable as brass. However, it’s affordable and able to last many uses.


Product Specs

  • Material: ABS plastic
  • Max PSI: 160 PSI
  • Extra Features: None

Pros

  • Protects RV hoses and plumbing to prevent damage
  • Automatically lowers water pressure at campsites to 40 to 50 PSI
  • Fits garden hoses and most other standard hose threads
  • No maintenance or adjustments required

Cons

  • Plastic isn’t as durable as metal alternatives

If you hate taking a shower under the mediocre flow of a low-pressure RV shower, then you’re going to like what the JR Products Hi-Flow Water Regulator offers. This compact part is able to safely reduce high levels of water pressure at campsites or other water sources, all while continuing to deliver a high flow that satisfies all of your water needs. Made out of lead-free brass with heavy-duty construction so it’ll last you many, many trips, this regulator automatically lowers pressure to its pre-set level of 50 to 55 PSI. You don’t have to fuss with anything at all. It’ll work with your standard RV hoses and lines, making it easy to hook up and detach as you travel. 


The only real downside? If you want more control over your water flow, this RV regulator isn’t adjustable, so you only get the 50 to 55 PSI it can provide.


Product Specs

  • Material: Brass
  • Max PSI: 160 PSI
  • Extra Features: None

Pros

  • Durable lead-free brass construction
  • Automatically takes high pressure down to 50 to 55 PSI
  • Works with standard 3/4-inch hose fittings
  • Thick, heavy-duty design 

Cons

  • Not adjustable

Our Verdict on RV Water Pressure Regulators

We picked the Renator Water Pressure Regulator as the best overall RV water pressure regulator because it offers a great combination of convenience and accuracy, allowing you to reduce high-pressure flows down to a safe level without difficulty. Plus, it’s nicely durable. And if you’re looking for affordability and value, you can’t go wrong with the Camco Brass Water Pressure Regulator with Gauge.

What to Consider When Buying RV Water Pressure Regulators

RV water pressure regulators are pretty simple components at first glance, and they all perform the same job in similar ways. But that doesn’t make picking out a quality regulator any easier. In order to find the best options for your RV and all-around protection for your RV’s plumbing, we’ve got all of the advice you need. 

Types of RV Water Pressure Regulators

In-Line Barrel 

This is the cheapest type of pressure regulator you can purchase. Typically, these regulators will allow you to control water pressure to within 40 to 45 PSI and are not adjustable. 

In-Line Barrel High Flow 

As the name implies, an in-line high-flow water pressure regulator is designed to work with higher water pressure. However, it’s not adjustable. High flow models tend to be more expensive than other types.

Adjustable 

Adjustable water pressure regulators allow you to do exactly that, adjust the pressure of the water flow. These models will typically feature a water pressure gauge that provides a numerical reading of the actual PSI from the intake. This style of regulator is often preferred because it allows for customization. 

RV Water Pressure Regulator Key Features

PSI Capacity

The PSI capacity refers to the amount of PSI, or pressure per square inch, that an RV water pressure regulator can manage. Your target range is going to depend on your specific recreational vehicle model and the amount of PSI it’s rated to handle. Typically, many water pressure regulators are factory pre-set to 45 PSI. 

Brass Construction

Even if you don’t use your RV regularly, when you do take it for a spin, you’re most likely going to be using the plumbing and appliances frequently. That means you’re going to be using a lot of water and you need to have a water pressure regulator that works properly and consistently. Look for products that are designed from sturdy materials. Most regulators are designed out of brass and are meant for long-term use. 

Low Lead Or Lead-Free Content

You don’t want lead in your water in your residential home, a drinking fountain, or your RV. In addition to your RV’s built-in water filtration system, one of the best ways to minimize the chances of drinking water with lead in it is to avoid installing accessories on your water lines that have lead composition. All of the brands we featured in this guide, as well as others we researched, clearly identify that they are either lead-free or have low lead content to within approved limits as specified by governing agencies like the EPA.

RV Water Pressure Regulator Benefits

Control water pressure

One of the most important factors of an RV water pressure regulator is its ability to control high water pressure. Most RVs can safely handle a PSI between 40 and 60. But depending on the location, some places can have pressures as high as 100 PSI. 

Avoid plumbing issues

If you allow too much water pressure to flow through your RV, you can damage appliances or end up with burst pipes. This can lead to costly repairs. A quality water pressure regulator can help you avoid these scenarios. 

Filtration

When you connect to a water supply, you have no way of knowing what type of sediment or obstructions are in the water. A quality RV water pressure regulator features a water filter to prevent blockage from rocks and other items that could be in the water supply.  

Sturdy construction

An RV water pressure regulator is a critical component that you will most likely use on a consistent basis to protect your vehicle’s plumbing. Look for models that feature heavy-duty materials and are rated as rust-resistant or are able to withstand extreme hot and cold weather. 

Gauge

You can find RV water pressure regulators that don’t feature a gauge. The choice to use one is entirely up to you. However, for precise measurements, especially if you’re concerned about carefully measuring the water pressure, we highly recommend opting for a pressure regulator that comes with a gauge.

RV Water Pressure Regulator Brands to Know

Camco

Camco is one of the most popular outdoor gear brands on the market. In addition to creating RV water pressure regulators, the brand also focuses on the ATV, camping, and boating categories. While the company is headquartered in the United States, it has production facilities around the world and is one of the most respected RV accessories brands. However, it is best known for its RV water pressure regulators.

Renator

Renator is a brand that is made by and for RV enthusiasts. The U.S.-based company was founded by an RV owner who realized that the available RV water pressure regulators that were on the market weren’t long-lasting, reliable, or affordable. Renator prides itself on the quality of its products and the low-lead levels in each of its regulators. The company only crafts RV water pressure regulators, so you’ll have peace of mind that it has expertise in this field.

Valterra

If there’s a name that’s synonymous with all things RVs, it’s Valterra. One of the most reputable brands in RV gear and components, this company specializes in hoses, hose fittings, sewer equipment, and other water and plumbing equipment for campers of all sizes, makes, and models. And when it comes to water pressure, Valterra is one brand you won’t want to overlook. 

RVAqua

RVAqua isn’t a big name in RV parts in general, but this brand does specialize in one particularly important area: hoses and plumbing for your camper. Opt for one of the water-ready products from RVAqua, and you’ll be choosing items that are specifically designed for RV use and the different elements and challenges that kind of equipment can survive.

Leisure Coachworks

Plus, it offers relatively affordable components when it comes to hoses, plumbing, and fittings. 

RV Water Pressure Regulator Pricing 

RV water pressure regulators can be found for as little as $5. At this price point, they usually won’t feature a gauge, can’t be adjusted, and are often made of plastic. The majority of the water pressure regulators on the market today cost between $20 to $40. They typically include a pressure gauge, are of brass construction, are lead-free, contain an RV water filter for rocks and debris, and are adjustable to accommodate a wider range of PSI.

Tips and Tricks

As with something you do for decades upon decades, you pick up a few tips and tricks along the way in terms of selecting the right product, and/or using it. That’s the case with us and RV water pressure regulators. To help you bridge the information gap, here’s a selection of what we’ve learned along the way.

  • Your target PSI will depend on whether you have a newer or older RV model. As a general guideline, newer RV models are designed to handle PSI levels as high as 100, while an older model should not have an intake of more than 50 PSI. Still, it’s recommended that even if you have a newer model, your RV plumbing shouldn’t receive more than 60 PSI.
  • You should perform regular maintenance on your RV water pressure regulator to guarantee the best performance. Inspect it for any cracks or damage to the interior and exterior. If it has a filter, check it to make sure that it’s intact.  
  • RV water pressure regulators are critical because at many campsites and rest stops, the facility won’t control the PSI flow rate. Sites don’t always advertise this fact. That means that if you aren’t experienced with RV camping and you don’t come prepared with a lead-free water regulator, you could be setting yourself up for serious RV plumbing and water damage when you connect your lines to a campsite. 

FAQs 

You’ve got questions. The Drive has answers!

Q: How do I install an RV water pressure regulator?

A: Installing an RV water pressure regulator shouldn’t be a hassle. Most models feature a simple two-pronged design with NH threads that are clearly labeled for input and output and fit with most standard hoses. Attach the external hose from the campsite or rest stop to the input thread and attach your RV’s water hose to the output NH thread. 

Q: How do I know if it’s time to replace my RV water pressure regulator?

A: One of the best ways to tell if it’s time to replace your RV water pressure regulator is if the water pressure from your faucets or shower head is low or inconsistent. This would indicate that the regulator is broken. Always check with your owner’s manual to confirm before replacing it. 

Q: How do I adjust the pressure on my RV water pressure regulator?

A: Adjusting the pressure is easy to do. But in order to do this, you must first have an adjustable water pressure regulator. Assuming you do, most models will feature a screw that can be turned either right or left to increase or decrease the pressure.
