Stainless steel RV water pressure regulator for campground and city water hookups, designed to help protect RV plumbing and hoses from high-pressure water while maintaining safe, consistent flow.
The Camco 40054 stainless steel water pressure regulator is designed to help protect RV plumbing, hoses, fixtures, and water system components from damage caused by high-pressure campground or city water connections.
Campground water pressure can vary widely from site to site. Installing a pressure regulator at the water source helps reduce incoming pressure before it reaches the RV water hose, filter, city water inlet, water heater, faucets, toilet valve, and interior plumbing.
Helps reduce high campground water pressure before it enters the RV
Durable construction for outdoor RV water hookup use
Reduces water pressure to a safe, consistent operating range
Attaches to standard 3/4" garden hose-style water connections
Camco 40054 is commonly listed as a stainless steel regulator that reduces water pressure to approximately 50-60 PSI. If your RV manufacturer requires a lower pressure range, verify your RV owner’s manual before use. This model does not include a pressure gauge, adjustable dial, built-in check valve, or cap unless otherwise stated.
Before Starting: Confirm your RV water system can use a 50-60 PSI regulator and inspect the campground spigot, hose washers, regulator threads, drinking water hose, and city water inlet before connecting. Basic Use Steps: 1. Turn Water Off: Make sure the campground or city water spigot is turned off before connecting. 2. Attach Regulator to Spigot: Connect the female end of the regulator to the water source when possible. 3. Connect Drinking Water Hose: Attach the RV drinking water hose to the outlet side of the regulator. 4. Add Filter if Used: If using an inline water filter, install it according to the filter manufacturer’s flow-direction instructions. 5. Connect to RV: Attach the hose to the RV city water inlet or freshwater system connection. 6. Turn Water On Slowly: Open the spigot gradually and check all fittings for leaks. 7. Monitor Water Flow: Confirm faucets, toilet, water heater, and other fixtures operate normally. 8. Disconnect and Drain: After use, turn off the water source, relieve pressure, disconnect, drain, and store with freshwater equipment.
Package Contents: • 1 Camco 40054 stainless steel water pressure regulator NOT Included — May Also Need: • RV drinking water hose • Inline water filter • Hose washers or replacement seals • 90-degree hose elbow • Quick-connect fittings • Pressure gauge • Adjustable water pressure regulator, if adjustable output is required • Hose caps or storage bag This listing is for the pressure regulator only unless otherwise stated. Confirm whether your setup also needs a hose, filter, gauge, elbow, washer, or adjustable regulator.
To confirm this regulator is right for your setup, consider the following: • Your RV manufacturer’s recommended incoming water pressure • Whether you need a preset or adjustable regulator • Whether you need a pressure gauge for visible PSI readings • Whether your water filter should be installed before or after the regulator • Whether the campground spigot and hose use standard garden hose threads • Whether your RV city water inlet needs a 90-degree hose elbow to reduce strain Why this matters: A pressure regulator helps protect RV plumbing, but it does not replace leak inspection, winterization, filter replacement, or proper freshwater system maintenance.
Match this regulator by pressure range, connection style, freshwater-only use, and whether you need a preset or adjustable regulator with a gauge.
If water pressure or flow issues continue, check campground water pressure, hose washers, inline filter condition, hose routing, RV inlet screen, and whether your RV needs a different PSI range.
Use this regulator only for potable freshwater hookups. Do not use with sewer rinse hoses, black tank flush systems, fuel, oil, chemicals, wastewater, or non-potable systems. Always confirm your RV manufacturer’s recommended water pressure range before connecting to city water, and disconnect/drain the regulator before freezing temperatures.
