Reliable Water Pressure Control for Any RV Setup

This Camco adjustable brass water pressure regulator is one of those small RV essentials that makes a big difference. It threads on easily, feels solid, and the brass construction gives it a heavy-duty, long-lasting feel compared to cheaper plastic versions. I like that it's adjustable—being able to fine-tune the PSI means I can protect my RV plumbing without sacrificing water flow at the sink or shower. The gauge is clear and easy to read, and the regulator doesn't leak or hiss under pressure. After a few camping trips, it's still holding strong and working perfectly. Definitely worth keeping in every RV toolkit.

Should be standard equipment for any RV. Easy to use. Protects your RV from water systems with high water pressure and is adjustable.

Great for travel trailer

Works great on my travel trailer. Was noticing the fixed pressure regulator wasn't working quite right.
