Best RV Water Pressure Regulators
Compare fixed and adjustable campground water regulators by gauges, connection details and RV plumbing compatibility.
Compare Current OptionsA campground spigot can supply more pressure than an RV water system should receive. An inline regulator reduces that exposure, but the product choice is not simply a contest of the highest PSI printed on the package. Fixed models are easy to use; adjustable models provide control but also create the possibility of an unsafe setting. This guide separates those roles using documented model features, without claiming independent pressure testing.

01 RV regulator shortlist
The key distinction is whether the regulator is fixed or adjustable; a visible gauge alone does not establish adjustability.
Camco lists the 40055 as a brass RV/marine water pressure regulator. It suits an owner who wants a straightforward pressure-reducing fitting without a gauge or tuning mechanism.
Camco’s 40064 adds a pressure gauge to its brass regulator configuration, giving a visible reading without making the regulator user-adjustable.
Camco documents an adjustable brass regulator with an integrated gauge and standard garden-hose threads. It allows a pressure setting chosen to match the RV plumbing specification.
Valterra lists a lead-free brass adjustable regulator with a gauge and inlet screened washer; its documentation warns that settings above 60 psi are not recommended.
Renator documents an adjustable brass regulator with a liquid-filled gauge, inlet screen and 45 psi factory preset.

Camco 40055 Brass Water Pressure Regulator
Camco lists the 40055 as a brass RV/marine water pressure regulator. It suits an owner who wants a straightforward pressure-reducing fitting without a gauge or tuning mechanism.
Best application: An uncomplicated campground connection where the RV maker permits the regulator’s output range.
Trade-off: No gauge or user-adjustable pressure; confirm the output against your RV manual.

Check PriceCamco 40064 Brass Water Pressure Regulator with Gauge
Camco’s 40064 adds a pressure gauge to its brass regulator configuration, giving a visible reading without making the regulator user-adjustable.
Best application: Owners who want to see downstream pressure but do not need to tune the setting.
Trade-off: A gauge is not an adjustment screw. Verify reading accuracy and inspect for leaks.

Check PriceCamco 40058 Adjustable Water Pressure Regulator with Gauge
Camco documents an adjustable brass regulator with an integrated gauge and standard garden-hose threads. It allows a pressure setting chosen to match the RV plumbing specification.
Best application: Owners who regularly encounter different campground pressures and want a configurable setting.
Trade-off: Do not dial above the RV manufacturer’s rated inlet pressure. This is not a substitute for confirming the safe operating limit.

Check Price04 Seven water-hookup safety checks
The correct regulator still needs proper pressure settings, hose placement and inspection.
- Find the RV plumbing pressure limit: Read the RV owner manual or water-system label. Do not treat a campground pedestal or regulator maximum as the RV’s safe pressure.
- Decide whether pressure adjustment is necessary: Fixed models are simple; adjustable models help when campground inlet pressure varies, but require correct setup.
- Confirm the fitting and hose direction: Check the pedestal spigot, regulator inlet and potable-water hose threading before tightening; avoid forcing mismatched fittings.
- Install upstream of the drinking-water hose: Position the regulator at the campground supply where the manufacturer directs so the downstream hose and RV connection are protected.
- Set and verify pressure under flow: For adjustable models, follow the specific adjustment instructions and check the gauge while a fixture runs, if the manufacturer directs.
- Inspect washers, screen and gauge: Replace worn sealing washers; clean an inlet screen when specified and check for leaks, gauge damage or freezing.
- Protect the system from freezing and contamination: Drain and store the regulator according to its manual; use drinking-water-safe hoses and sanitation procedures. A regulator does not filter or disinfect water.
05 Match the regulator to the hookup
Want a basic protective fitting? The Camco 40055 is a straightforward fixed-pressure option. If you also want a pressure reading without adjusting it, consider the Camco 40064.
Want to tune the pressure? Camco 40058, Valterra A01-1117VP and Renator M11-0660R are documented adjustable alternatives. Use the RV manual’s pressure limit rather than the highest setting available on the regulator.
Having weak water flow? Diagnose clogged inlet screens, undersized hoses, filters and low campground supply pressure before increasing the regulator setting. See our RV water hose guide and RV water filter guide after those roadmap pages are published.
06 Frequently asked questions
Do I need a water pressure regulator at every campground?
Using a compatible regulator when connecting to an unfamiliar city-water supply is a sensible precaution because supply pressure can vary. Follow the RV manufacturer’s water inlet requirements.
What PSI should I set my RV water pressure regulator to?
Use the pressure specified by your RV manufacturer. Some regulators have factory presets, but those do not override the RV plumbing rating.
Is a regulator with a gauge better than one without?
A gauge helps show the downstream pressure. It does not make a fixed regulator adjustable, and it does not replace checking the RV’s maximum permitted pressure.
Where should the RV pressure regulator be installed?
Many inline RV regulators are intended at the campground spigot before the drinking-water hose, protecting the hose as well as the RV. Follow the specific product instructions.
Does a water pressure regulator also filter drinking water?
No. A screened inlet washer may catch coarse debris but is not a potable-water filter or disinfection device. Use appropriate filtration and water-safety practices separately.
Can I use an adjustable regulator at 60 PSI or higher?
Only when the RV plumbing manufacturer explicitly permits the pressure and the regulator documentation allows it. Valterra advises against settings above 60 psi for its A01-1117VP; other RV limits may be lower.
07 Protect the RV plumbing first
For simple city-water hookups, a fixed regulator may be sufficient. If you camp across locations with variable supply, an adjustable model with a readable gauge offers more control—provided you use the RV maker’s approved pressure limit. Neither design replaces filtration, hose maintenance or correct installation.
