Recap: Best RV Water Pressure Regulators

How to Choose the Right Water Regulator

Keeping your water system functional is essential for a fulfilling camping adventure. The right RV water pressure regulator makes your work easier by ensuring that your water pressure is correct. However, with different brands and models, you can find it challenging to settle on the best regulator. Below are some factors we considered in our research criteria.

Adjustable vs. Inline Barrel Regulators

There are two types of regulators in the market-the adjustable type and the inline barrel type. The adjustable regulator makes it easier for you to make adjustments to the pressure to fit your needs. With the inline barrel type,  you cannot adjust the water pressure. Also, it’s made to control between 40-45 PSI. When deciding on the type of regulator, check to see that it fits your RV’s plumbing system and that it’s specific to your requirements.

You can also find a modified version of the thin-line barrel RV water pressure regulator. This type of regulator works with high water pressure, but it’s not adjustable. It’s also more expensive compared to other models.

Brass vs. Other Materials

Check the material that’s been used to make the regulator when shopping around.  Most regulators contain brass, which is durable, sturdy, and resistant to elements like rust and corrosion. You should also opt for a regulator that can withstand frequent and long-term use. The material should prevent water contamination.

PSI Capacity and Lead Content

When comparing the different models, pay attention to PSI capacity, construction, and lead content. Pressure per square inch or PSI is the amount of pressure that a regulator can handle, essentially determining your flow rate. The target range depends on your RV and the amount of PSI it’s rated to manage. Most regulators are preset to 45 PSI. You also need to find a regular with low lead content or one that is lead-free, which minimizes your chances of drinking water that contains lead. 

Your water softener can also help you remove any minerals or other contaminants. If you’re looking for precise measurements, you’ll want to get a regulator with a gauge. The gauge will help you measure the correct water pressure.

The Brand

You can find a quality water pressure regulator from renowned brands like Camco, Valterra, among others. Our top pick list includes some brands popular for their quality build, durability, and resistance to corrosion and rust even with long-term use.


The market has various types of regulators with differing price ranges. Nonetheless, you should also look at the durability, functionality, and reliability apart from price when comparing the water pressure regulators. You can find regulators that range from $15 to some that go for over $40. Look at the long-term cost benefits like flooding, blocked water lines, and burst pipes that can be expensive to repair, and choose a regulator that can serve you for years even if you need to pay a few more bucks.
