Camco Brass RV Water Pressure Regulator Review – Simple, Cheap Protection for Your RV Plumbing
Is the Camco Brass RV Water Pressure Regulator (40055) Worth It?
If you just need a simple, inexpensive way to protect your RV plumbing from high campground water pressure, the Camco Brass RV Water Pressure Regulator is a solid, time-tested option.
Based on hundreds of recent buyer reviews plus manufacturer data, it:
- Reduces incoming water to roughly 40–50 PSI, which is a safe range for most RV plumbing systems.
- Is made from lead-free brass and is certified to NSF/ANSI 372 low-lead standards, so it’s drinking-water safe.
- Typically earns well over 4 stars out of 5 from RVers and homeowners, though there are consistent complaints about reduced flow and limited long-term durability in hard-water or year-round use.
Best for:
- RV owners who want a cheap, plug-and-play safety device on every city-water hookup
- Campers who don’t care about seeing the exact PSI and mainly want “set it and forget it” protection
Not ideal for:
- RVers who want high flow for long showers or multiple fixtures at once
- Full-timers in very hard-water areas or those who want an adjustable regulator with a gauge
Why RV Water Pressure Regulators Matter (and Where Camco Fits In)
If you’ve ever turned on your RV faucet and felt like a fire hydrant just moved into your kitchen, you already know why water pressure matters. Campground “city water” can easily spike 80–150 PSI. That’s more than enough to:
- Burst flexible water hoses
- Stress fittings and PEX lines
- Damage faucets, toilets, and water heaters over time
Most RV manufacturers recommend keeping pressure around 40–60 PSI. That’s the job of a water pressure regulator.
The Camco Brass RV Water Pressure Regulator (40055 ) is one of the most common solutions you’ll see tossed in RV starter kits and recommended in forums. It’s a fixed-pressure, non-adjustable brass regulator that screws between the spigot and your hose and drops pressure to a safer range (around 40–50 PSI).

Quick Verdict
The Camco Brass RV Water Pressure Regulator is a budget-friendly, no-frills way to protect your rig’s plumbing. For most weekend campers and many seasonal RVers, it does exactly what it claims: drops high city water pressure down to a safer level and helps prevent hose or plumbing damage.
However, it does reduce water flow noticeably, and many long-term users report that it can clog or fail after 1–2 years, especially in hard-water conditions or year-round use. If you want precise control, maximum shower pressure, or you camp full-time, an adjustable high-flow regulator with a gauge is a better match.

What Real Owners Like – Pros
From dozens of recent reviews, some very clear “pro” themes show up again and again.
1. Solid Brass Construction & No Leaks (for Most Users)
Many reviewers mention that the regulator feels heavy and well made right out of the box. Words like “solid construction,” “heavy brass,” and “good quality” pop up repeatedly.
- Owners using it on RVs, garden hoses, docks, and yard hydrants say it feels far more robust than cheap plastic regulators.
- For a large portion of buyers, once they add a fresh rubber washer or a bit of Teflon tape, they report no leaks at the connections, even over months of use.
For the price, most people feel they’re getting good value in materials and build.
2. Clearly Reduces High Pressure to a Safe Level
Multiple reviewers used stand-alone pressure gauges and measured the improvement:
- One user saw campground water around 70 PSI and reported the Camco dropping it to about 40 PSI, which matched exactly what they wanted.
- Another saw 80 PSI at the spigot; after the regulator, the downstream gauge at the RV inlet showed around 30 PSI when they had an additional adjustable regulator in series.
- Several RV owners mention that after installing this piece, their hoses stopped swelling, and they were no longer worried about bursting hoses or damaging appliances.
In other words, it does what it promises: takes potentially dangerous “city water” and tames it.
3. Simple, “Set-and-Forget” Design
Lots of buyers appreciate how straightforward it is:
- Screw it onto the spigot
- Attach your drinking water hose
- Turn on the water
There’s no need to fiddle with settings, watch a gauge, or think too much about it. Many RVers leave it attached to their hose end all season and only notice it when they unhook.
4. Versatile Beyond the RV
Although it’s marketed as an RV product, reviews show people using it to:
- Protect garden hoses and yard hydrants from high municipal pressure
- Prevent sprinkler heads and hose timers from blowing out
- Reduce pressure for pool fillers and other outdoor taps (with mixed success when very high flow is needed)
This versatility means if you eventually upgrade to a fancier RV regulator, the Camco can easily be reassigned to yard duty.
5. Affordable Enough to Keep a Spare
Many experienced RVers treat this regulator as a consumable item:
- They keep one on the rig and one as a backup, in case it gets left on a spigot or fails on the road.
- Several reviewers specifically say they bought a second one for a friend or second hose because the price was reasonable.
For budget-minded campers, that low cost + decent performance is a big part of the appeal.
What Real Owners Complain About – Cons & Trade-Offs
No product is perfect, and the critical reviews are consistent about a few issues.
1. Noticeable Drop in Water Flow
The single biggest recurring theme: reduced flow.
- Quite a few RV owners say their showers became a trickle, or it felt like the faucet was only “¼ turn open” when this regulator was in line.
- Some measured their city pressure at around 40 PSI, added the Camco as extra protection, and found the pressure dropped too low to comfortably wash dishes.
- Owners using it for driveway cleaning or high-flow sprinklers often switched back to a different regulator because it slowed the water too much.
In fairness, this is partly the trade-off of fixed regulators set around 40–50 PSI—they prioritize safety over high flow. But if your park pressure isn’t extremely high to start with, this regulator can feel too restrictive.
2. Durability: Seizing, Clogging, and Short Lifespan for Some
A noticeable number of long-term users report that after months to a couple of years, the regulator:
- Clogs or seizes internally, cutting flow to almost nothing
- Starts to restrict flow far more than when it was new
- Occasionally develops internal leaks or erratic behavior (pressure surges, then drops to a trickle)
In several cases, users traced this to sediment, minerals, or sand in the water. One RV owner solved the issue temporarily by back-flushing the regulator and adding a sediment filter upstream.
The pattern: this regulator often works great initially, but in hard-water or year-round outdoor setups, it may become a replace-every-year-or-two part.
3. Leaks at Swivel or Gasket
While many reviewers report zero leaks, a smaller but consistent group says they had:
- Drips from the swivel joint in the middle of the body
- Leaks from the hose-side gasket out of the box
- Situations where they needed pliers or channel-locks to fully tighten both ends
Some fixed the issue by replacing the washer or using extra Teflon tape. Others concluded that once the mid-body swivel leaked, the unit was basically done, since that joint isn’t user-serviceable.
4. No Gauge, No Adjustability
Quite a few 3–4-star reviews sound like this: “It works, but next time I’d buy the adjustable one with a gauge.”
Common frustrations:
- You can’t see the exact PSI, so you’re trusting that it’s still regulating correctly.
- You can’t tweak the pressure higher if you want a stronger shower or lower if your rig’s rating is very conservative.
- You don’t know when it’s wearing out—only that the flow is getting worse.
For basic protection, that’s fine. But if you’re a full-timer or a detail-oriented RVer, this can be limiting.
5. Too Much Restriction for Some Use Cases
A subset of reviewers using the regulator for:
- Washing machines
- Pool auto-fillers
- High-flow sprinklers
found the pressure reduction to be too aggressive. They either had to barely crack the faucet or ditch the regulator entirely for those tasks.
Who the Camco Brass Regulator Is Best For (and Who Should Skip It)
Best For You If…
You’ll likely be happy with the Camco Brass RV Water Pressure Regulator if:
- You’re a weekend camper or seasonal RVer who wants basic burst protection and isn’t too picky about having the strongest shower.
- You frequently hook up to unknown or high-pressure campground water and want a cheap safety net on every connection.
- You’re okay treating the regulator as a consumable: if it clogs after a year or two of heavy use, you’ll simply replace it.
- You like simple gear—no gauges, no knobs, just screw it on and know you’re in the safe zone.
For many RVers, especially those just starting out, this is a sensible first regulator that dramatically lowers the risk of plumbing disasters.
You May Want Something Else If…
Consider an adjustable, high-flow brass regulator with gauge instead if:
- You’re a full-time RVer or spend months at a time in parks with hard or sediment-heavy water.
- You’re very sensitive to low water pressure and want home-like showers where possible.
- You run multiple fixtures at once (e.g., washing machine + shower + sink) and can’t afford a big flow reduction.
- You like being able to dial in pressure for different rigs (maybe you own more than one RV, or you also regulate pressure for your sticks-and-bricks home).
Our broader guide on regulators walks through those adjustable options and when they make sense:
Mini Real-World Stories (Paraphrased from Owner Reviews)
A few owner scenarios illustrate how this regulator behaves in real life:
- High-pressure campground hero
One camper tested the water at an RV park spigot and saw very high pressure that made them nervous. After adding the Camco regulator, the pressure dropped to a much safer range and stayed there for a 3-day stay—no leaks, good flow for their needs, and peace of mind that their plumbing wasn’t being hammered. - From “swollen hose” to calm water line
Another user with a 200-foot hose noted that before the regulator, the hose would bulge under high pressure. Once they installed the Camco at the faucet, the downstream pressure measured about 30 PSI (with another regulator in line), the hose relaxed, and they still had enough flow for normal use. - Garden hose & yard hydrant saver
Several homeowners with very high city pressure (over 140 PSI) used this regulator on outdoor spigots to prevent hoses, sprinklers, and timers from blowing apart. In those cases, the trade-off in flow was acceptable, and they considered it cheap insurance. - When it starts to clog
On the flip side, there are multiple reports where the regulator worked perfectly at first but, after months of use, flow steadily dropped. In one case, the owner restored performance temporarily by blasting water backwards through it and then adding a sediment filter in front.
These stories match the broader pattern: excellent short-to-medium-term protection, but you may need to watch for performance changes if you leave it on a high-use line long-term.
Installation & Usage Tips (From Real-World Experience)
Even though it’s simple, a few small habits can make your Camco regulator work better and last longer.
Basic Hookup Steps
- Turn off the campground spigot completely.
- Thread the regulator onto the spigot (female end to faucet) and hand-tighten using the “ears” on the collar.
- If needed, add a fresh rubber washer and a wrap or two of Teflon tape to the faucet threads to prevent leaks.
- Attach your RV drinking water hose to the outlet (male) end of the regulator.
- Connect the hose to your RV city-water inlet.
- Slowly turn on the spigot and watch for leaks at each joint. Tighten gently as needed—avoid overtightening to the point of damage.
- Once flow is stable, check inside the RV (faucets, toilet, shower) and make sure everything behaves normally.

Pro Tips to Get the Most from the Camco Regulator
- Use it at the spigot, not at the RV
Putting the regulator right at the faucet protects both your hose and the rig from excess pressure. - Add a sediment filter upstream in gritty water
In parks with sandy or silty water, a simple inline filter before the regulator can help prevent internal clogging over time. - Don’t let it freeze full of water
Several owners saw early failures after a light frost. Before freezing weather, disconnect, shake out water, and store the regulator somewhere dry. - Back-flush occasionally
If flow starts dropping and you suspect sediment, disconnect and blast water through it backwards. Some owners report that this temporarily restores normal flow. - Treat it as a wear item
Especially if you’re hooked up full-time, assume this is a part you may replace every year or two, just like a cheap hose washer or filter cartridge.

FAQ – Camco Brass RV Water Pressure Regulator
Q1. What pressure does this regulator reduce to?
The Camco Brass RV Water Pressure Regulator is factory set to keep outlet pressure in the 40–50 PSI range under normal flow.
Most RV manufacturers consider that a safe range for protecting plumbing and fixtures while still providing reasonable flow.
Q2. Is it safe for drinking water?
Yes. The regulator is made from lead-free brass and is CSA low-lead certified to NSF/ANSI 372, which means it meets U.S. federal and state requirements for low-lead drinking-water components.
You can safely use it on your fresh-water line feeding your RV.
Q3. What thread sizes does it use?
It uses standard 3/4″ garden hose threads (GHT):
- Female connection on the inlet (attaches to campground spigot or hydrant)
- Male connection on the outlet (attaches to your RV water hose)
So it works with typical RV drinking water hoses and outdoor faucets in the U.S. and Canada.
Q4. Do I still need a water filter if I use this regulator?
Yes. This device only regulates pressure; it does not filter sediment, chlorine, or contaminants. If you’re concerned about water taste or debris, pair it with an inline or canister filter on the same line.
For more about protecting your rig’s water system overall, see:
Q5. How do I know if it’s still working correctly?
Signs it’s time to inspect or replace the regulator:
- Your flow drops significantly compared to when it was new.
- You notice erratic pressure—strong at first, then dropping to a trickle.
- Water starts leaking from the body or mid-swivel, not just the threads.
Because this model has no gauge, the easiest way to verify performance is to use a separate screw-on pressure gauge at the RV inlet. If the gauge shows very low PSI or no change when bypassing the regulator, it may be clogged or worn.
H2: Final Verdict – Is the Camco Brass RV Water Pressure Regulator a Good Buy?
Overall, the Camco Brass RV Water Pressure Regulator lives up to its reputation as a simple, cost-effective way to protect RV plumbing from high campground water pressure.
What it does really well:
- Drops potentially damaging city water pressure into the 40–50 PSI safe zone for most RVs
- Uses lead-free brass and is certified for drinking-water use
- Installs in seconds with standard garden-hose threads
- Offers an affordable “insurance policy” against burst hoses and stressed fittings
Where it falls short:
- It reduces flow noticeably, especially if your starting pressure isn’t extremely high
- There’s no gauge or adjustment, so you can’t fine-tune or monitor PSI
- In long-term or hard-water setups, enough owners report that it can clog or fail within 1–2 years that it’s smart to treat it as a wear item
So, who should actually buy it?
- If you’re a weekend or seasonal RVer who wants basic, reliable pressure protection at a low cost, the Camco brass regulator is an easy recommendation.
- If you’re just building out your RV setup checklist and want a must-have safety item to go alongside hoses, filters, and surge protectors, this belongs in your tote. (You can see more gear ideas in our broader accessories guide at RV Accessories.)
- If you’re a full-timer, demand strong showers, or camp primarily in hard-water parks, you’ll likely be happier upgrading to an adjustable regulator with a gauge—the extra cost buys you better flow and visibility.
If you’re okay with the trade-offs and just want something simple that works, the Camco Brass RV Water Pressure Regulator is still one of the most popular entry-level choices for a reason.
