Water pressure regulators are incredibly important in your van or RV.
They control the pressure of the water, prevent plumbing issues, and filter your water supply.
Most vans can handle a water pressure (measured in pressure per square inch, PSI) of between 40 and 60, although water supplies can be anywhere up to 100 PSI.
The pressure regulator prevents highly pressurized water from entering your van’s pipes. This water has the potential to cause burst pipes or structural damage.
The water filter protects your pipes by preventing rocks, sediment, and debris from entering and blocking your pipes.
We have rounded up and reviewed the top 5 water pressure regulators for vans available on the market. There is a buyer’s guide included to ensure that you know what qualities to look for in a water pressure regulator.
At the end, we have written a handy FAQ section to answer any outstanding questions that you may have.

Best Van Water Regulator Buyers Guide
What Type of Water Pressure Regulator?
There are 3 main types: in-line barrel, in-line barrel high flow, and adjustable.
Adjustable water pressure regulators do as they state on the tin. They provide you with the capability to change the water pressure at will. They will have a gauge indicating the PSI of the water intake.
In-line barrel is the most economical pressure regulator that you can buy. They are not adjustable and tend to only work for water with a PSI of 40 to 45.
In-line barrel high flow regulators are also non-adjustable. They are similar to the in-line barrel but operate at a higher pressure level. These are often the most expensive pressure regulators.
Water pressure regulators for vans can be found for a wide range of price points, from $5 to $100! The cheaper regulators tend to be made from plastic and are unlikely to include a gauge. They are non-adjustable and are pre-set to a PSI range.
Most water pressure regulators cost somewhere in the realm of $15 – $40. They are made of lead-free brass and have a pressure gauge. Regulators at this price tend to have an adjustable PSI range and will incorporate a water filter for rocks and debris.
The most expensive versions are of a higher build quality. They are very effective in operation but do not offer any additional features that cannot be found in the mid-range versions.
While you do not have to spend a lot of money on your pressure regulator, it could be worth investing in a high-quality one. Burst pipes and other issues caused by incorrect pressures in your water system can be much more expensive than even a top-end regulator.
Some good brands for pressure regulators are Renator, Valterra, and Camco.
If you are unsure of which brand to get, consider checking out customer reviews for a true indication of quality.
This is the maximum water pressure that your regulator can handle without incurring damage. They are often pre-set to around 45 PSI, but you can get more variable regulators. The PSI capacity you will need depends on your van’s PSI rating.
Your van’s inbuilt water system will be designed to withstand water pressure of up to 100 PSI. Many campgrounds will often get up to around 150 PSI in their water supply.
A regulator that is preset to around 50 PSI will allow you to use the campgrounds’ water supply without causing irreparable damage to your vehicle.
For optimum longevity, the PSI inside your van should be kept at around 40 to 60. This will ensure no leaks occur or pipes burst.
When looking for a water regulator, we recommend opting for one constructed from brass. This is a sturdy and durable metal that does not rust. At worst, it will tarnish and corrode but it will still be usable.
Brass regulators can withstand a lot of water passing through without degrading in quality. They are also able to withstand temperature extremes well.
You should look for water pressure regulators that have a low lead content, or ideally, that are lead-free. Lead is a toxic substance to the human body, and so it is wise to minimize your intake wherever possible.
The easiest way to do this is to choose lead-free materials for all elements in your water system. The Environmental Protection Agency (EPA) and National Sanitation Foundation (NSF) have listed approved limits for lead content of water systems, so if you are unsure look for this.
If you are interested in closely monitoring your water pressure, you should opt for a water pressure regulator with a gauge.
You should try and see how easy it will be to install the regulator onto water outlets and your drinking water hose.
The harder it is to do, the less likely you will do it correctly and this could cause issues with your water supply.
A good way to check this is to read customer reviews and speak to other van drivers. They will have first-hand experience and knowledge that will be invaluable to you.
Warranty and Customer Service
If your water pressure regulator is faulty in any way it can cause severe damage to be incurred to your van.
It is a good idea to look for companies that have dedicated customer support channels. This gives you some assurance that in the event something does go wrong, you will be able to catch and repair it quickly.
A warranty period is a quick way to see how much faith the manufacturer has in their product.
This seems obvious but is easy to forget. Most water pressure regulators for vans use the standard ¾ inch connector size. This is used in most places and means that you are likely to be able to work the regulator no matter where you end up.
It is always worth checking in your van’s owner’s manual to confirm the size of the socket. Some will use a ½ inch socket, meaning a standard pressure regulator will not work.
Frequently Asked Questions
How Do You Install a Van Water Pressure Regulator?
Park up at the campsite in your desired location. Connect the pressure regulator to the water supply.
You will next need to connect the drinking water hose of your van to the other end of the pressure regulator. This will ensure the pressure going through the hose is not too high and no damage is sustained.
How Do You Remove a Van Water Pressure Regulator?
It is very simple to remove. Twist the hose to loosen and detach it.
Twist the regulator and remove it from the water tap. If you struggle to do this with your hands, you can use a pair of pliers. Take great care not to damage it.
How Do You Adjust a Van Water Pressure Regulator?
You cannot do this alone, and you must have someone to assist you. This is because as you adjust the pressure on the regulator, someone must check the water inside your van.
Your first step is to find the external bolt on your water pressure regulator. There will be a locking nut attached which will need loosening.
Once you have loosened this but you will be able to turn the bolt which adjusts the water pressure.
To increase the pressure, turn the bolt clockwise. To decrease the pressure, rotate it counterclockwise.
Keep an eye on the pressure reading on the regulator gauge. When it reaches 50 PSI you should retighten the nut.
You have now successfully adjusted your van’s water pressure regulator.
Do You Need a Van Water Pressure Regulator?
It is not completely necessary to install a water pressure regulator on your van, particularly if you do not intend to connect to city water supplies.
This being said, we would strongly recommend you install one on your van. This is because the pressure of the water supply found in campsites varies widely. This makes it very difficult to know what water supplies will cause damage to the plumbing of your van.
A van water pressure regulator will ensure that you never supply more than 60 PSI water to your van, and can prevent costly damages from occurring.
What Are The Symptoms of a Bad Water Pressure Regulator?
The clearest symptom of a bad water pressure regulator is a severe drop in the water pressure of your van. If your pressure drops suddenly or is non-existent, this is likely the cause.
If this is the case, replacing the water pressure regulator should fix this instantly. If this does not solve the problem there are a few other potential causes.
If your water hose is kinked, cracked, or clogged this can cause a drop in pressure. You can unkink the hose, or in the case of severe damage, replace it altogether.
Your water filter may be dirty which could reduce the volume of water that can travel through. This can be fixed by replacing the water filter.
The same principle applies to a clogged mesh at the water inlet, or a clogged regulator. These can be rectified by replacing these component parts.
If you have checked and tried all of these, the problem may be caused by the water supply itself. A way to make the water pressure feel higher is to add aerators. These can be added to faucets and shower heads to make the water pressure feel stronger.
How Long Do Water Pressure Regulators Last?
Generally speaking, an average water pressure regulator should last for around 10 to 15 years.
The parts that cause your regulator to break are the spring and rubber gasket. They can wear away over time through use and should be checked regularly for signs of damage and wear.
