7 Best RV Water Pressure Regulators: Fixed & Adjustable

by Joshua Thomas

One of the main problems that many RV owners face when camping at the camping ground is high water pressure.

Indeed, most of the time, the water pressure is not regulated at the camping ground and many times, the pressure is so excessive that it can damage the plumbing system of your RV.

This is where the high-flow RV water pressure regulator comes into action. Basically, this regulator is simply a 3/4 inch threaded accessory that you place in your RV plumbing system such that it automatically regulates the water pressure to a safe water pressure level.

One of the best things about this already accessory is that it is extremely affordable and yet will very effectively protect your RV plumbing system from damage.

This will prevent you from spending thousands of dollars down the line repairing your plumbing system simply because the water pressure was not regulated in the first place.

Therefore, if you are the proud owner of an RV, then the water pressure regulator is an absolute must-have!

How to Buy the Best RV Water Pressure Regulators

How To Buy An RV Water Pressure Regulator
How To Buy An RV Water Pressure Regulator

Before finding a top-rated RV water pressure regulator, there are some important aspects to take into account. Here are the most important ones you need to keep an eye out:

1. Fixed or Adjustable RV Water Pressure Regulator

When you are looking to buy an RV water pressure regulator, you will find 2 types: the fixed pressure regulator and the adjustable one. Both have its advantages and disadvantages.

The main advantage of the adjustable RV water pressure regulator is that it will regulate the pressure depending on your need and purpose.

You do not always require the same amount of pressure and this is where the adjustable pressure regulator becomes useful. The main disadvantage is that the adjustable pressure regulator is usually more expensive than the fixed model.

For those on a small budget, the fixed RV water pressure regulator is a right choice. This type of pressure regulator usually works similarly to a water hose connector.

You will not be able to adjust the water pressure with this type of pressure regulator, but if you only need to protect your RV plumbing system from excessive water pressure, then this is an excellent choice that will not cost you much.

2. Water pressure gauge

The water pressure gauge will allow you to see the actual pressure at all times. Remember that water pressure is measured in PSI and all water pressure gauges attached to an RV water pressure regulator will use PSI as their metric.

Indeed, having a gauge on your water pressure regulator can be useful if you need to know with great precision the water pressure that the regulator is calibrated to deliver.

Many models make the water pressure gauge very easy to read, so you will not have a problem in telling the pressure even when looked at a distance.

3. Material

The material used in your RV water pressure regulator is very important. Basically, it will dictate the durability, and the drinking safety of the water pressure regulator both in the short term and in the long term.

Most manufacturers choose to use stainless steel and brass as those metals are affordable, lead-free, and highly durable materials that will not rust, crack or break under intense water pressure. Additionally, they do not react with water and therefore the water remains safe for drinking.

Therefore, brass or stainless steel are ideal materials that you should look for when purchasing an RV water pressure regulator. The only caveat is that it can cost a little bit extra.

If you are on a strict budget, some models are made from a high-grade ABS plastic that is equally durable even if it is made from plastic.

One of the main advantages is that a plastic RV water pressure regulator will usually cost less than a stainless steel one. However, durability is definitely not the same as stainless steel is tougher.

4. Connector Size

Most RV water pressure regulators use the same connector size of 3/4". This is a standard plumbing socket size, so you will have no difficulty fitting your water pressure regulator anywhere in your RV plumbing system or connecting it to a garden hose thread.

However, some RV plumbing systems use a 1/2" socket size. Therefore, you must make sure that you are purchasing a water pressure regulator of the correct size.

5. Price

In general, the RV water pressure regulator is not a very expensive RV accessory. However, you should still make a budget before you purchase this accessory and try to stick to this budget at all times.

In our experience, a quality RV water pressure regulator should not cost you more than $25 for a model without a gauge and less than $50 for a model with a gauge.

Conclusion

As we have seen, the RV water pressure regulator is an important accessory for your RV. It will regulate the water pressure and ensure that the plumbing system of your RV is safe and does not break under excessive water pressure provided by your campground.

Furthermore, this RV accessory is quite versatile as it allows you to regulate the water pressure to your liking. You will not experience poor water pressure at the outlet when using the RV water pressure regulator, quite the contrary.

Finally, our RV water pressure regulator review above lists some quality models you may want to consider. If you have still not found a suitable model, you may have missed something. We recommend that you go through the review one more time.
