STMOUTUO RV Water Pressure Regulator 45 PSI

This adjustable STMOUTUO RV water pressure regulator protects RV plumbing by limiting incoming pressure and filtering debris. It ships preset to 45 PSI and includes a 0–160 PSI gauge and raw tape for water pipe connections, so you can verify and fine tune the output before running faucets. The brass, lead-free construction follows NSF guidance for low lead content and aims to reduce wear and burst risk on camper lines while keeping water cleaner thanks to the inlet screen.

Key features

Compact and straightforward, the regulator reduces excessive pressure to safer levels for campers, trailers, and RVs. Installation is tool-light, just thread the 3/4 inch hose connection to a standard US water source and tighten. If you need a different output, a screwdriver lets you increase or decrease pressure by turning the adjustment screw. Note that the unit is preset at 45 PSI by the manufacturer, and the included gauge reads up to 160 PSI for broad monitoring. STMOUTUO RV Water Pressure Regulator appears sturdy and functional, and the inlet filter helps block sediment before it reaches your plumbing. ⚙️🔧

Usage tips

It’s a great fit if you want simple protection for an RV or trailer plumbing system and a quick way to confirm pressure with an on-body gauge. For best results, flush the supply line briefly before connecting, check the gauge after installation, and make small adjustments to the screw while water is flowing to reach the desired pressure. Keep in mind that very hard water or heavy sediment may require occasional cleaning of the inlet screen to maintain flow.

Care & maintenance

Rinse the inlet screen periodically and inspect the regulator for buildup, especially after using unfamiliar campground water. Store the regulator dry when not in use to prevent mineral deposits. Regular checks of the gauge help spot changes in supply pressure before problems occur. 🧰💧.
