Top 10 Best RV Water Hose Pressure Regulators

Best RV water pressure regulators

Water is an integral component for enjoying many activities, RVing included. You need water for your RV, and that often means connecting up to a city water connection. Unfortunately, it’s unlikely the water flowing out of a city water connection at a campground is monitored. Hence the water pressure at different campgrounds is going to vary. 

Whether you experience very high-pressure water coming out or low pressure, either one can lead to issues. Luckily, you can utilize a straightforward strategy to this dilemma and add a water pressure regulator. So let’s take a look at what a water pressure regulator can do for you.

If the water pressure is too low, you’ll not have adequate water flow into your RV. While this is rather annoying, it is not the end of the world. However, if water pressure is too high, it can cause damage to your plumbing fixtures, appliances, and RV. In addition, it can potentially lead to leaks and water damage that you will undoubtedly want to avoid.

How Does an RV Water Pressure Regulator Work? 

A water pressure regulator is simply a valve that reduces the water pressure coming from your water source. As mentioned above, if the water coming from your water source comes to your RV with too much pressure, it will damage your RV. The water pressure regulator stops that from happening by reducing the water pressure before it reaches your hose and RV plumbing.

The correct water pressure for an RV will vary depending on the model and the condition of your RV’s plumbing system. Though some modern RVs can handle up to 100 psi of water pressure, most RV plumbing experts recommend that you never let the water pressure exceed 60 psi. Thus, somewhere between 40 to 50 psi is going to be ideal for most RVs. Your RV’s owner’s manual will recommend the ideal water pressure for best performance.

Several different types of RV water pressure regulators are available to choose from. Generally, there will be adjustable and non-adjustable water pressure regulators. The non-adjustable options come in either low flow or high flow designs. Adjustable water pressure regulators with a gauge allow you to dial in the proper water pressure, and the indicator consistently shows you what the psi is.

Now, knowing the importance of controlling your RV water pressure, it’s time to look into purchasing a water pressure regulator. You can narrow down your options by reviewing the recommended regulators listed below.

Top RV water pressure regulators


Many people may wonder if an RV water regulator is needed. Maybe they’ve even camped for years without one and never had a problem, or perhaps it isn’t easy to justify spending money on more camping gear. We understand these viewpoints, but we wholeheartedly recommend RV water pressure regulators as a critical accessory to extend the functional lifespan of your RV’s plumbing.

When you invest in an RV, you will want to take good care of it using proper accessories for your RV’s water system. For example, RV water lines are more delicate than traditional plumbing, and water pressure that is too high will quickly damage these lines, resulting in leaks that are difficult to track down and costly to repair. The RV water pressure regulators mentioned above can help with this.
