The Valterra RV Hi-Flow Water Regulator is exactly what you need if you want to regulate high-pressure flows for a newer-model RV, as this device is designed to regulate the water pressure inside the RV to 50 to 55 PSI to better protect the tank and your ride.

It’s easy to install too and connects directly to any standard faucet or hose fitting the water regulator is available in two metals, brass, and stainless steel. The brass option is rust-resistant, sturdy, and durable even after years of operation and stress. This certainly makes for a heck of a difference when it comes to shower water pressure too.

There have been issues with the device leaking when first connected and you may have to add a rubber washer ring to the regulator to prevent it from leaking.

Another big letdown is the regulator does not come with a PSI gauge so you can’t see how much pressure is being used. It also may be difficult to remove from the attachment after you are done using it.

Pros:

• Automatically regulates pressure to 50 to 55 PSI
• Two durable metal choices
• Delivers a high flow rate despite lowering pressure
• Connects to standard fittings

Cons:

• Will need a rubber washer added to prevent leaks
• No PSI gauge
• Can be difficult to remove
