Overview
The Camco 40055 Brass Water Pressure Regulator is a fixed-pressure regulator designed for installation between a campground spigot and an RV freshwater hose. Camco states that it reduces incoming water pressure to approximately 40–50 PSI and is made from lead-free, drinking-water-safe brass. Standard 3/4-inch garden hose threads make it a straightforward choice for owners who want pressure control without a gauge or adjustment knob.
Because the output is fixed, the regulator is simple to use but does not display the actual pedestal pressure or allow fine adjustment. Owners should confirm the RV manufacturer’s recommended inlet-pressure limit and investigate unusual low flow rather than assuming that every restriction is caused by the regulator.

Key Features
- Fixed regulator intended to reduce incoming water pressure to approximately 40–50 PSI.
- Lead-free, drinking-water-safe brass construction, according to Camco.
- Standard 3/4-inch garden hose threads for common RV and marine freshwater connections.
- Inline design requires no gauge, calibration, or manual pressure adjustment.
- Compact, removable configuration for campground and city-water hookups.
RV Use Cases
- Campground hookups where supply pressure is unknown or may be higher than the RV plumbing system should receive.
- Seasonal or extended-stay connections where a regulator remains installed at the water source.
- Owners who prefer a fixed-pressure device instead of an adjustable regulator with a gauge.
- RV or marine freshwater systems using standard 3/4-inch garden hose connections.
Practical Advantages and Limitations
Advantages:
- Simple setup with no pressure adjustment or calibration required.
- Compact brass body is easy to install, remove, and store.
- A fixed output range can provide straightforward pressure control when it matches the RV manufacturer’s limits.
Considerations:
- The regulator does not show the actual supply or regulated pressure.
- The fixed output cannot be tuned for a specific RV or campsite condition.
- Mineral deposits, debris, a worn hose washer, or a damaged fitting can reduce flow or create leaks.
- A regulator does not replace inspection of the hose, fittings, city-water inlet, or the RV manufacturer’s pressure guidance.
Best Practices
- Confirm the limit first: Review the RV manufacturer’s recommended inlet pressure before connecting to an unfamiliar water supply.
- Install at the source: Attach the regulator to the campground spigot before connecting the freshwater hose.
- Inspect each setup: Check the washer, threads, and connections for debris, wear, seepage, or damage before pressurizing the system.
- Investigate low flow: If water flow changes, check the supply, hose, washer, and regulator for restrictions before changing equipment or increasing pressure.
- Store it dry: Drain and dry the regulator before storage to limit mineral buildup and make damage easier to spot.
- Use a gauge when precision matters: Choose an adjustable regulator with a pressure gauge when the RV or campground conditions call for closer monitoring.
Inspector’s Note (RV Pro Solutions Insight)
Campground water pressure can be all over the place. A simple regulator like this is an economical way to take some of that extra pressure off your RV’s plumbing and fixtures. It connects at the water source before your freshwater hose, with a fixed setting that keeps the hookup straightforward.
There’s a practical camping benefit, too. When you have water hookups but no sewer connection, a strong, long shower can fill the gray tank quicker than you expect. Getting familiar with your shower’s water use helps you figure out how many showers and days you can enjoy before it’s time to dump. It’s one of those things you learn about your own RV as you use it.
