The Camco 40055 Brass Water Pressure Regulator is a simple, reliable tool designed to protect your RV’s plumbing system from potentially damaging high water pressure at campgrounds or city water hookups. Built from durable brass, it helps ensure a consistent water pressure flow of approximately 40–50 PSI, safeguarding plastic lines, faucets, and fixtures inside your RV.
This model is a favorite among RVers for its ease of use — simply attach it to the campground spigot before connecting your freshwater hose, and it automatically regulates pressure without the need for manual adjustment.
Key Features
- Maintains safe water pressure (40–50 PSI) to prevent leaks or burst lines
- Solid brass construction for long-lasting corrosion resistance
- Standard ¾” garden hose threads for universal RV compatibility
- Simple “inline” design — no tools or adjustments required
- Lead-free and compliant with low-lead laws for potable water use
RV Use Cases
- Prevents over-pressurization damage to RV freshwater lines during campground hookup
- Ensures consistent flow when using city water connections or external water sources
- Ideal for long-term RV stays where varying water pressures are common
Common User Feedback
Pros:
- Durable brass build that lasts through multiple seasons
- Reliable performance with steady pressure output
- Quick and easy to install without extra fittings
Cons:
- Fixed (non-adjustable) pressure setting
- May reduce flow slightly compared to adjustable regulators
- Exterior brass can tarnish over time if not stored dry
Best Practices
- Install at the source: Always attach the regulator directly to the campground spigot before your freshwater hose.
- Inspect regularly: Check O-rings and threads for debris or wear before each trip.
- Store dry: Allow to air dry before storage to prevent corrosion or mineral buildup.
- Upgrade option: For variable water pressure environments, consider an adjustable model with a gauge.
Inspector's Note (RV Pro Solutions Insight)
As a certified RV inspector, I view water-pressure control as a simple way to reduce unnecessary stress on fittings, valves, and supply lines. This fixed regulator is practical for owners who want a straightforward setup, but the important step is confirming that its regulated output is appropriate for the RV manufacturer's plumbing limits. I would also inspect the washer, threads, and inlet screen regularly and replace the regulator if flow becomes inconsistent or the body shows damage.
