So, these are the 8 best RV water pressure regulators in the market today. It seems you won’t go wrong when you choose any one of these.

What is an RV Water Pressure Regulator?

An RV water pressure regulator is a plumbing valve that is used to reduce the water pressure coming from the main water line into the camper. This device ensures that the pressure is kept at a safe level before the water goes through any pipes or plumbing fixtures inside the rig.

The RV water pressure regulator is installed in the RV to help reduce the water pressure. The is designed to take on the high water pressure coming from the water supply system which usually reaches up to 150 psi. It is able to reduce that amount of pressure from 80 to 50 psi which is safer for your RV’s plumbing system.

Some experts recommend that we keep the water pressure within 50 psi. This is also beneficial in cutting the cost of your water bills and reducing water waste in your camper.

Without the regulator, pipes can burst from the high pressure of the water. RVers will also encounter problems such as dripping faucets, running toilets, and leaking sprinkler valves. It would also cause costly damages to the appliances that you have inside your camper such as your refrigerator, dishwasher, washing machine, and water heater. If you don’t have a water pressure regulator in your RV, it is probable that the strong water pressure will damage the appliances and fixtures inside your rig.

You can usually find the RV water pressure regulator at the rig’s main water line, right after the primary shut-off valve. This is a strategic location since it makes it easier for users to shut off the main water line should they need something done on the water pressure regulator.

It may be a small device but its benefits are enormous. It is essential in keeping the water pressure within your rig at a safe level.

Take note that water pressure is quite tricky. If it is too low, then it is hard for you to take a shower or wash the dishes. If slightly high, you may experience leaks in the toilet and faucet. But if the pressure is too much, your pipes and plumbing fixtures can burst and water will reach your appliances and other valuables inside the rig.

This is why it is important that you have a water pressure regulator in your RV so you can control the pressure of water that goes through your rig.

How Does it Work?

The RV water pressure regulator usually works with the help of a spring-loaded diaphragm that is adjustable. The valve works by allowing you to control the flow of water into the passageways. You can open, close, or partially obstruct the way depending on your chosen settings.

But since we want to keep the water pressure at a safe level, you want to constrict the valve. So that from high pressure, you can expect the water pressure to go down after it goes through the valve. This is how it reduces the amount of water that enters your RV. In doing so, it also lowers the risk of damages in your pipes and the joints and fittings in your plumbing system.

Benefits of RV Water Pressure Regulators

An RV water pressure regulator is a small device but it is very useful to have. Here are the advantages of using a water pressure regulator in your RV.

Regulates pressure

This is the primary purpose of an RV water pressure regulator. It ensures that the water pressure that enters into your rig is kept at a safe level. This usually means that the pressure is kept within 50 psi.

With the water pressure being regulated, you won’t have to worry about your pipes suddenly bursting open or constant leaks in your faucet, shower, and toilet. When you’re using an adjustable regulator, you can even control or adjust the water pressure that gets into your RV’s water system. This will help you determine if you’re meeting the recommended level for it to function effectively.

Can help save your plumbing fixtures 

The constant flow of water causes wear and tear on your pipes and faucets. And if there is high pressure, there is more strain on these fixtures which can cause them to break or burst open.

When you use a water pressure regulator, the amount of pressure is kept at a manageable level so that it doesn’t cause too much stress on your plumbing fixtures. This will prolong the life of your pipes and faucets and make sure that they function efficiently.

While we’re in this topic, it is also recommended that you regularly replace the seals and gaskets along your plumping system to be sure that there are no leaks.

Can save your onboard appliances and devices

Your RV washing machine, dishwasher, and water heater are just some of your appliances that rely on the availability of water for you to be able to use them. And if the water rushes through them in a fast manner, then they might not be able to handle that kind of pressure.

This is why it is important to regulate the water pressure inside your rig so that you can protect your appliances. These are valuable investments on your part and you wouldn’t want to see them damaged.

Just imagine the cost of replacement and the inconvenience you have to deal with when they’re rendered kaput. Take note that most manufacturers of appliances void the warranty when the damage is caused by extremely high water pressure. To think that you can do something about it. By simply using an RV water pressure regulator, you can save your appliances and devices in your camper.

Prevents water from flooding your RV 

When there are leaks, water will flow continuously and can cause flooding inside your vehicle. More so when the water pipes suddenly burst open.

You have to clean the mess and some appliances and devices can get damaged because of the flooding. That is why it is best to use a reliable RV water pressure regulator so that you can have peace of mind that there’s no flooding that will happen inside your rig.

Saves water, energy, and wastewater

Again, when there are leaks and water flows continuously inside your camper, you are wasting water. Water supply is very important when you’re on the road.

With a water pressure regulator, the pressure is kept at a safe level. Without it, the water pressure can go as high as 150 psi. This means that water flows twice as much and most of this goes to waste. So when you use a regulator, you are able to conserve water and reduce your wastewater.

It is also beneficial in saving energy because it makes sure that only the right amount of water goes into your plumbing system. For those using hot water inside your rig, using a regulator can help you save as much as 30% of the required energy to heat the water. This means you not only save on energy but also on corresponding costs.

So, a water pressure regular makes your camper conserve water and more energy efficient.

Prevents elements from getting into your constant supply of water 

Another useful feature of RV water pressure regulators is that they can filter unwanted elements such as gravel and dirt from getting into your water system. It ensures that the water that flows into your rig is clean and safe. This also helps prevent these harsh elements from causing damages in your plumbing system.

Lead-free 

For those who are concerned about the possible lead content of RV water pressure regulators, you can be assured that these devices are free of lead. This will help you ensure the safety and cleanliness of your water supply inside the rig.

Some water pressure regulators are made of brass. These are sturdy, durable, and lead-free. You might find some regulators with minimal lead content but manufacturers keep it at a very low level so as not to compromise water safety.

Sometimes it is hard to imagine that such a small device can have this much impact in your camper. With all these advantages, it just proves that having a water pressure regulator in your camper is a must!

Types of RV Water Pressure Regulators

RV water pressure regulators come in different types. You need to know the properties of each type so that you’ll know which one fits your RV the best.

In-line barrel 

This type of water pressure regulator can limit the water pressure in your rig to approximately 40 to 45 psi. It is able to decrease the pressure coming from the main water line and restrict the flow of water in your RV.

It is able to keep the water pressure in your RV within a safe level. It is also very affordable. However, you cannot adjust the pressure when you use an in-line barrel regulator.
