Camco Brass Inline Water Pressure Regulator Review

A camco water pressure regulator is a great tool for RVing.

There’s a wide range of products on the market to protect your RV. A quick stroll down the aisle, and you’ll find everything from expensive electrical management systems to protective pads for your landing gear. Some of the equipment are luxury items, and others are essential for keeping your RV in like-new condition. Let’s look at why we think you should pick up a Camco water pressure regulator the next time you’re out shopping.

Brass Inline Camco Water Pressure Regulator Overview

The Camco Brass Inline Water Pressure Regulator helps protect your RV’s plumbing and hoses. These are susceptible to damage when exposed to excessive water pressure.

The Camco water pressure regulator reduces high water pressure to a safer 40 to 50 PSI. The brass construction is not only durable but also safe for drinking water.

At less than $10, this is a must-have RV accessory no matter how often you’re using your rig.

Why a Water Pressure Regulator is a Must-Have for Your RV

A leak or busted water line in your RV’s plumbing system is no joke. These two failures can quickly cause thousands of dollars in damage and put your RV out of commission for weeks or even months. 

Your RV lines may be capable of handling 100 to 125 PSI. However, RV manufacturers recommend you not exceed 40 to 50 PSI.

If you do experience damage due to excessive water pressure, you’ll likely incur a hefty repair bill. Many manufacturer warranties exclude damage caused by unregulated water pressure.

What We Love About the Brass Inline Camco Water Pressure Regulator

This Camco water pressure regulator has several features that make it a popular choice among RVers. Let’s take a look at why we think you should consider it too.


While many RVing accessories can be expensive, this water pressure regulator isn’t. For less than $10, you’ll have peace of mind that your RV is safe from high pressure.

Despite the budget-friendly price of this water pressure regulator, it gets the job done.

Reduces Water Pressure to 40-50 PSI

Providing optimal working conditions for your RV’s water lines is essential for the longevity of your system.

Manufacturer warranties vary in length and coverage, but many won’t cover damage caused by unregulated water pressure.

Using this water pressure regulator limits the pressure and helps avoid extensive damage and costly repairs.

Durable and Easy to Install

With a solid brass construction, this water pressure regulator is incredibly durable. The durable construction is great, but the ease of installation is even better.

The Camco water pressure regulator quickly and easily attaches to any three-quarter-inch water connection.

Connect one end of the regulator to the water connection and connect your potable drinking hose to the other end.

Your potable water hose can then connect to either the city connection or tank fill connection on your RV water system. 

Cons of the Brass Inline Water Pressure Regulator

Despite the many benefits of the Camco water pressure regulator, it does have a con. Let’s take a closer look.

Not Adjustable

The Camco water pressure regulator is not adjustable and restricts water flow to 40-50 PSI no matter the scenario.

A non-adjustable regulator could be cumbersome should you need something other than 40-50 PSI. This feature limits the device mostly to RV-related uses.

The Camco water pressure regulator is an excellent product, but it’s not unique. If you’re shopping for a quality water pressure regulator, we have a couple of great suggestions.
