Hourleey Water Pressure Regulator for RVs, Brass 3/4" Inlet with Gauge and Screened Filter (0–160 psi)

Hourleey’s brass water pressure regulator valve keeps RV and camper plumbing safe by letting you set and monitor inlet pressure up to 160 psi while filtering debris.

Installed at the fresh-water connection of an RV, travel trailer or camper, this compact regulator gives you visible control over incoming municipal or campground water pressure. Its lead-reduced brass body, built-in inlet screen and clear gauge simplify hookup and protect hoses, fittings and onboard fixtures from excessive pressure or grit. The top-mounted adjustment screw makes changing the output pressure quick and tool-free, and the standard 3/4" threaded inlet fits most American garden and RV hoses.

How do I set and read the pressure correctly?

Adjusting the outlet pressure is done with the screw on the regulator's crown — turn clockwise to raise and counterclockwise to lower. The integrated dial shows inlet pressure at a glance so you can confirm the regulator is protecting your system. Tiny gauge bubbles may appear after temperature changes or movement; they don’t affect performance.

• Adjustable range: 0 to 160 psi for fine control
• Top screw allows quick, on-site pressure tuning
• Clear analog gauge displays current inlet pressure
• Minor gauge bubbles are normal after temperature shifts

Will this fit my RV hose and fixtures?

The valve uses a 3/4" threaded connection that matches standard U.S. garden and RV hoses, so it connects directly to most campground spigots without adapters. Internal threads accept common fittings used on fresh-water inlets and hose assemblies. Always inspect and replace gaskets if worn to prevent leaks at the joint.

• 3/4" threaded joint compatible with American hoses
• Works with most RV fresh-water inlet styles
• Includes inlet screened filter to catch sediment
• Check or replace gaskets when installing to avoid leaks

What materials and safety features does it have?

The regulator is crafted from lead-reduced brass with a lead content well below common thresholds, reducing potential contamination risks compared with traditional alloys. A stainless or brass-screened inlet traps sand and debris before it enters the trailer plumbing. The clear gauge gives continuous pressure feedback so you can correct issues before damage occurs.

• Lead-reduced brass body for durable, safer water contact
• Built-in inlet screen filters grit and particulates
• Visible gauge for ongoing pressure monitoring
• Robust construction suited to outdoor and mobile use

How do I maintain and troubleshoot the regulator?

Routine checks include inspecting the inlet screen and replacing the seal if signs of wear or leakage appear. If the gauge shows strange readings after transport, let the assembly sit so trapped air clears; small bubbles in the gauge are normal and usually resolve on their own. Tighten fittings to hand-tight plus a quarter turn — avoid overtightening which can damage threads or gaskets.

• Clean or replace the inlet screen if flow reduces
• Replace gasket when you detect persistent leakage
• Allow trapped air to clear if gauge shows bubbles
• Avoid excessive torque on threaded joints

Who this is for: RV owners, campervan and travel-trailer enthusiasts, and anyone who connects a mobile living space to external water sources will benefit from this regulator. It’s especially useful for those who frequent different campgrounds or municipal hookups where inlet pressure and water quality vary. Install it as part of your regular hookup routine to protect plumbing, maintain steady water flow and reduce the risk of damage from high pressure or sediment.
