When you own an RV, you can bring all the comforts of home on the road with you but sometimes, when you’re setting up camp, you just can’t get the same water pressure you’re used to. If you’ve ever been frustrated by the less-than-stellar (or even too high) water pressure coming from your campsite’s hookups, you aren’t alone. Plenty of RV owners discover they can only get a trickle of water or can’t connect properly to high-pressure water lines when they’re setting up camp. But there’s a simple and effective tool you can use to take control of your water pressure: a pressure regulator. With an RV water pressure regulator, you’ll be able to increase or decrease the pressure to your liking so you can get exactly the flow you like no matter where you travel. Easy to find in a variety of forms and styles, we’ve rounded up some of the best RV water pressure regulators you can buy right here.

Best RV Water Pressure Regulators Reviews & Recommendations

The Renator Water Pressure Regulator Valve is an easy-to-use device that’ll give you far more control over your RV’s water pressure every time you hook up. Made out of brass, and lead-free according to NSF lead-free requirements, this regulator is durable and has a built-in gauge that arrives with oil already inside to reduce and prevent friction on the internal components. And you’ll be able to adjust your water pressure up to 160 PSI max.

Backed by a one-year warranty, this water pressure regulator is compatible with all U.S. water sources and it’ll even work with 3/4-inch garden hose threads and NH threads for total compatibility. With this regulator installed on your RV, you’ll have great control over flow and pressure. However, you may find that its flow is a little less compared to similarly-sized products. It’s up to your personal preferences to decide if it’s enough of a flow for you.

The Camco RV Brass Inline Water Pressure Regulator is a product that packs plenty of value, and it’s an especially great choice for those who want a regulator that’s affordable on any budget. Designed to reduce the high pressure you can get when you’re hooking up to city water sources, this small little tool will protect your RV’s plumbing by allowing you to reduce water pressure when needed. It’ll take high-pressure flows down to a consistent 40 to 50 pounds of pressure.

Made out of durable brass (and to meet CSA low lead certifications), it’s made to last a long time. And this water pressure regulator attaches easily to your RV thanks to its 3/4-inch garden hose threads. Keep in mind, though, that sometimes this regulator can leak and doesn’t include a gauge so you can see what kind of water pressure you have at the water tap, which keeps you a bit in the dark.

You can adjust up or down depending on your needs from 0 to 160 PSI, and the easy-to-read gauge lets you see and select exactly the right pressure settings.

But perhaps the biggest perk of all? This RV water pressure regulator includes an inlet screened filter, which prevents blockages and potential damage by keeping everything but water out of your hoses and RV water setup. Compatible with all U.S. water sources, this regulator offers great durability and adjustability. It can greatly improve your water pressure but do note that faulty products can slip through the manufacturing process. If yours begins to leak, you’ll want to contact Twinkle Star for a replacement ASAP.

It automatically regulates water pressure when you’re connected to a campsite’s spigot, keeping it between 50 and 55 PSI for safety. And it’s both easy to clean and easy to attach. The only potential downside? You can’t adjust the water pressure at all, so you’ll have to be comfortable at 50 to 55 PSI. Additionally, at some campsites, you may get even lower pressure of as little as 40 to 45 PSI.

You can opt to lower the water pressure for a high-pressure source or increase if needed for your preferences. You’ll be able to pinpoint the exact water pressure with this RV water pressure regulator, which is a nice feature. However, some RVs may require some kind of extension to be able to hook up to a water source. You might want to have a spare brass elbow or other attachment just in case.

How We Selected RV Water Pressure Regulators 

In order to separate the best RV water pressure regulators from all the rest, we considered and compared dozens of products available online. To narrow down that selection and choose the best in terms of quality and reliability, we took a look at the material each regulator was made out of and its design, taking details like included oil, screens, filters, and adjustability into consideration. We also examined the types of water sources and connections that each regulator worked with, along with reports and reviews of their reliability (and, of course, whether or not they leaked when used in the field).

Our product selections, rankings, and awards for this story are based on research. While we haven’t conducted real-world testing on all of these products yet, we’ve looked at consumer testimonials and data, tutorials, and general discussions on social media and in forums. We also consider price and specification in the context of the segment. And, of course, we rely on our institutional knowledge of the automotive landscape to weed out weak products.

Buying Guide/What to Look For 

As you start your search for a quality RV water pressure regulator, it can be a challenge to distinguish the best products from all of the rest. We’ve got all of the shopping advice you need right here, with guidance on what to look for and how to assess different regulators you’ll come across along the way.

What to Consider When Buying RV Water Pressure Regulators


In-Line Regulators

In-line regulators are the cheapest and most basic kind of RV water pressure regulator you can buy and use. These regulators are designed for just one purpose, and that’s getting high-pressure water sources down to a tolerable level (one that won’t cause problems or damage to your RV’s plumbing). This kind of regulator will bring your water pressure to 40 to 45 PSI.

The biggest drawback of an in-line regulator is you can’t adjust the water pressure. But in-line RV water pressure regulators come in two forms: in-line barrel and in-line barrel high flow. If you opt for a high flow model, you’ll be able to work with even higher water pressure. However, you still can’t adjust it to your personal preferences.

Adjustable Regulators

If you want to step up to a more advanced and customizable RV water pressure regulator, you can opt for the alternative to in-line barrel models: an adjustable regulator. With an adjustable water pressure regulator, you’ll be able to adjust the pressure of the water’s flow. These regulators typically come with gauges so you can read the pressure and then adjust to the exact PSI you’d like. It gives you more control over your RV’s plumbing and allows you to adapt to different situations. 

RV Water Pressure Regulator Key Features

Lead-Free Brass

To ensure your RV water pressure regulator is safe for your use (and for your RV’s water supply), you’ll want to make sure you consider only those regulators that are made from lead-free brass. Brass is a highly durable metal, and it performs well as a fitting for water sources. However, you want to opt for lead-free products so you know your water will be safe to consume, shower with, and use in general. 

3/4-Inch Threads

What good is an RV water pressure regulator if you can’t actually hook up to campsite water sources with it? Fortunately, most can just make sure you buy one with 3/4-inch threads. This is the size you’ll need to hook up to pretty much any U.S. water source, garden hose, or another form of water supply. You should also double-check that your regulator works with NH fittings too, for complete versatility in any situation. 

Easy-to-Read Gauge

If you’re opting for an adjustable regulator — or simply want to be able to tell what water pressure you’re getting with an in-line model — it’s a good idea to choose one with an easy-to-read gauge. This will allow you to see the water pressure as it comes from the source and into your RV. And if you’re able to adjust it, you can then tweak your pressure until it’s at just the right PSI for your needs. 

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.

  • Regulators that come with a built-in or optional screen filter can give you even more value, as they’ll weed out debris and prevent potential plumbing blockages.
  • Always take the PSI capacity into consideration when you’re choosing a water pressure regulator, as this will tell you how much pressure a regulator can actually handle.
  • You definitely don’t want leaks, so always take a look at any warranty (or lack of warranty!) on a regulator. If you spring a leak, your regulator will become useless, so it’s important to know you can get it replaced if so.


Q: What is the ideal water pressure for an RV?

You’ll notice that most RV water pressure regulators bring down water pressure to levels between 40 and 55 PSI. That’s because the range of 40 to 50 PSI is ideal for your RV’s plumbing system. While RVs can potentially handle as much as 100 PSI, 40 to 50 is best.

Q: Where should I put my water pressure regulator on my RV?

Your regulator should be attached between your water source (like the campsite hookup post) and your freshwater hose.

Q: Is 80 PSI too high for an RV?

Most modern RVs can technically handle up to 100 PSI, but that doesn’t mean it’s always the best choice. If you use water at 80 PSI consistency, you may run the risk of causing damage or excess wear on your RV’s plumbing system. Keep in mind that the 40 to 50 PSI range is the best indicator of whether or not your water pressure is too high.

Final Thoughts

Our pick for the best overall RV water pressure regulator is the Renator Water Pressure Regulator Valve, which is made of hardy material and keeps your pressure at just the right amount. However, if you’d like a more affordable option, the Camco RV Brass Inline Water Pressure Regulator can provide great value. Which regulator is your top choice?
