The Camco (40055) RV Brass Inline Water Pressure Regulator can be used to help protect your RV plumbing and hoses from high-pressure city water. Its lead-free design will help protect your drinking water while you travel.

Improving water pressure is as important as reducing the pressure of the water that comes into your RV. In fact, improving water pressure can actually be a better way of dealing with the problem of pressure than reducing the water pressure bringing into your RV. More water pressure can help get rid of waste from appliances and avoid having to refill water containers after every use.

Camco Brass Water Pressure Regulator

Pros:

  • Easy to install
  • Leak proof

Cons:

  • Plastic construction
  • Not very durable

Out of all the RV water pressure regulators we looked at, this one ranked at the top of my list due to only a few minor flaws. The Camco brass water pressure regulator with gauge is made from plastic just like the normal Camco 46329 model.

However, the fact that this one has a gauge makes it stand out from the rest. The “max” setting on this model can be adjusted easily from 45 to 60 PSI. The product also comes with red and black hoses.

6. Camco 40143 Plastic Water Pressure Regulator

Our rating: 7 / 10

Camco 40143 Plastic Water Pressure Regulator

Pros:

  • Inexpensive
  • Very Lightweight
  • Extra-insulation
  • Plastic construction

The Camco 40143 is one of the cheapest solutions on the market for reducing water pressure that comes inside your RV. This simple but effective device can extend the life of your RV plumbing.

This regulator works because it limits water pressure to 40 feet of vertical lift for city water pressure. If you have 2800 PSI water pressure, then you’ll need an 18 gallon per hour pump to run at full pressure while using the water regulator. Otherwise, if you have 3800 PSI, then you’ll need a 22.5 gallon per hour pump.

In addition to reducing water pressure, this product also comes with a shutoff valve to connect to your shower or tub. It also features a flexible hose that doesn’t require you to change any of your plumbing.

Do RV water pressure regulators go bad?

Water pressure regulators do not last forever. Although they may work for many years, they are eventually going to need to be replaced.

However, to make this a little easier to understand, there are two different types of RV water pressure regulators: Fixed and adjustable.

Fixed RV water pressure regulators have a metal screen with holes designed to restrict the flow of water. These regulators are NON-adjustable. You cannot increase the flow of water through the system by closing the holes further. This, along with the fact that RV water pressure regulators don’t last forever, is why providers of RV water pressure regulators typically only offer, fixed RV water pressure regulators and not adjustable models.

What is the correct water pressure for an RV?

The actual water pressure your RV needs is ultimately up to you depending on what you’ll be using it for, and the type of water supply that you have. Using common sense, you cannot expect your RV to fill up your bathtub with a water pressure of 40 PSI (pounds per square inch). Likewise, expecting to fill up your water tank by using high pressure setting on your hose is also not practical.

This kind of water pressure is uncomfortable and impractical, especially for daily uses in an RV. Excessive water pressure can cause banging and knocking on the pipes if the water pressure is too strong. The most common pressures for an RV are 20-40 PSI, which would be ideal for mainly using it for bathroom and kitchen utilities.

Where does the water pressure regulator go on an RV?

When you install the pressure regulator, you need to connect the line during your initial set up. The regulator should be plumbed into the outflow side of the RV's pressure tank. There is usually a small hole through the bladder (the air chamber) of the pressure tank. If you can't directly access the bladder or there is no hole there, you can drill one. Locate a nearby exterior wall section (such as a cabinet or wall) that can be used as an alternative access point.

There is usually a nearby pipe that leads from the pressure tank to the interior hot water tank. This is the pipe that you will connect the pressure regulator to. The pressure regulator will be positioned immediately before the pressure tank.

Conclusion

One of the main issues that people have when using their RV that they didn't consider ahead of time is the pressure they are receiving from their water lines. They think that it's the same as what they get in their home, but it's just not the case. It's crucial to understand that the pressure coming from the water company is a lot higher than you might need when it comes to doing things like dishes and taking a shower. That's why it's crucial to keep that pressure at a safe level with the help of the 7 best RV water regulators. We hope that you find the information that we have found helpful in finding the perfect solution for your needs.
