When the gas or propane exits the tank, a high level of pressure is present. between 100 PSi to 200 PSI and sometimes higher than that. It lands at about 250 PSI. That is why you need a regulator that slows this pressure and manages at a safe pressure as your source of energy.

Automatic changeover valves usually have a lever (or dial) that you use to select which cylinder is the primary one, with the other serving as the reserve tank or cylinder. They'll also have some sort of indicator that shows whether the primary cylinder is full of LP gas (green) or empty (red).

To use the automatic changeover valve, you must first turn the handwheels on top of both propane cylinders. If both cylinders are not open, the automatic changeover will not take place. On the automatic changeover valve, point the lever (or dial) to the cylinder you want to be the primary cylinder. The indicator will turn green, indicating that the primary cylinder is full of propane.

When the primary cylinder runs out of propane, the automatic changeover valve will automatically switch to the reserve cylinder, drawing propane from it. The indicator will turn red, indicating that the primary cylinder is now empty.

When the primary cylinder is empty (the selector lever will point to the primary cylinder), manually turn the selector lever to the reserve cylinder. The indicator will now turn back green because you turned the selector lever to make the reserve cylinder the primary cylinder.

After you've refilled the empty cylinder, reconnect it to the pigtail/propane hose and reopen the cylinder valve on top. When the primary cylinder runs out of propane, the automatic changeover will switch to the reserve cylinder.

Most Ideal RV Dual Propane Tank Setup

It can be a bit tricky to connect a regulator to your RV dual propane tank setup if you don’t have any experience with it. Here is a step-by-step guide to walk you through the process.

Step 1. Turn off your propane tanks and disconnect them from the old regulator you'll be replacing. Next, go inside your RV and turn on one of your stove's burners. This will empty the LP gas in the line, ensuring no gas escapes when the regulator is removed. Wait until the flame has gone out before turning off the gas on the stove so that it does not start leaking when you turn it back on.

Step 2. The propane regulator for RV is connected to the main gas line at the bottom. Place a wrench on the nut of the main gas line and twist the regulator to remove it. The main gas line should not be twisted because it is not designed to move.

If you're having trouble twisting the propane regulator by hand, use another wrench on the lower portion, which is usually hexagonal in shape and can be used with a wrench if necessary.

Step 3. Now, you must remove and retape the old yellow gas line tapes from the main gas line threads. Tape the propane regulator in the same direction you'll be screwing it on, so it doesn't move and come undone while you tighten it.

Step 4. All that's left is to connect the new RV propane regulator to the main gas line. For a good seal, use plenty of tapes and don't cross-thread the nut onto the bolt. Use the two crescent wrenches to tighten for a leak-free fit.

Step 5. After you've secured the LP gas regulator to the main gas line, simply connect the two pigtails to your LP tanks as you normally would. When you open the propane tank and point the arrow towards it, the monitor on the regulator should turn from red to clear.

Step 6: Check For Leaks: Now that propane gas is flowing through the regulator, inspect the connection between the regulator and the main gas line for leaks. You can do this by spraying or dumping a solution of water and dish soap on the connection. You have a strong connection if no bubbles appear. If bubbles appear, you may need to repeat all of the steps and use more gas line thread tape.

Difference Between Using a Regular and Propane Dual Regulator

There are two types of propane regulators for RVs: a regular regulator, commonly known as a single-stage regulator, and a propane dual regulator, known as the two-stage regulator. Here are the main differences between them.

A pressure reduction regulator is the safest way to reduce cylinder pressure to a usable level for operating equipment and instruments. Gas pressure regulators with a single-stage regulator minimize cylinder pressure to delivery or outlet pressure in a single step. A dual propane gas regulator reduces cylinder pressure in two steps. Because mechanical characteristics influence each regulator's performance, the choice between the two depends on what you’re using it for.

Droop and supply pressure effects are the two most important variables to consider. The difference in delivery pressure between zero gas flow and the regulator's maximum flow capacity is called droop. The variation in delivery pressure when supply pressure decreases as the cylinder empties is known as the supply pressure effect.

Single-stage and two-stage regulators have distinct droop characteristics and react to changes in supply pressure in different ways. Single-stage regulators show a slight droop with varying propane flow rates but the effect on the supply pressure is significant. On the other hand, two-stage regulators have a significant droop but only minor supply pressure effects.

When inlet pressure does not vary significantly, or periodic delivery pressure readjustment is not a problem, a single-stage regulator is usually recommended. On the other hand, a two-stage regulator ensures constant delivery pressure and eliminates the need for periodic readjustment.

Two Tank Propane Regulator for your RV: The Pros and Cons

First, it's essential to know that a two tank propane regulator is the same as a two-stage regulator. Two-stage regulators (also known as twin-stage regulators) work in two stages to reduce high pressure. They require less readjustment and deliver a more consistent delivery pressure regardless of inlet pressure changes. They're ideal for high-pressure cylinders.

Two-stage regulators feature two regulators built into a single regulator body. The first regulator (first stage) is preset at a non-adjustable pressure to reduce the incoming pressure to a lower, intermediate level. The second regulator (second stage propane regulator) can be adjusted within the desired delivery range.


  • While the first stage regulator is not adjustable, the two-stage regulator can be adjusted. They contain an additional stage which includes a second pressure adjusting spring, diaphragm, and valve seat assembly. The pressure adjusting spring is "pre-compressed" at the factory. This allows the first stage to feed pressure to the second (adjustable) stage.
  • It can be used when the propane appliance you are using cannot tolerate a rise in delivery pressure rise from the cylinder.
  • It is useful in situations where proper pressure is critical, and you have an external propane tank or the cylinders in use are in a remote location that it will be difficult to monitor.
  • It is typically not required when using gas from low-pressure regulator (<500 PSIG) sources.


  • It's significantly more expensive.

Frequently Asked Questions

Are all propane regulators the same?

All propane regulators serve the same purpose for the tank on which they are installed. However, depending on what the propane is being used for, there are various regulators available. You can choose either a high pressure or low pressure regulator.

The following are the most common propane regulators:

  • First stage regulators
  • Second stage propane regulators
  • Integral two-stage regulators
  • High-pressure regulators
  • Adjustable high-pressure regulators
  • Automatic changeover regulators

The type of regulator your propane tank requires is entirely dependent on the RV appliance(s) that you need to supply with gas. The regulator requirements of a restaurant with high-demand RV appliances, or a RV propane heater (like a tankless water heater) will be vastly different from those of a homeowner barbecuing with a gas grill.

When it comes to getting a propane tank, your propane supplier should be able to sit down with you and discuss your needs. They will provide you with a tank regulator that is tailored to your specific needs.

Do RV propane regulators go bad?

Your RV propane regulator should last for a long time, but it isn't indestructible. Replacing them every ten to fifteen years is a good idea. Even if you're not having any problems with your RV's propane system, the internal components eventually wear out. Before something goes wrong, it's a good idea to replace an old regulator.

How long do RV regulators last?

An RV gas regulator should last you a while with proper maintenance even if your gas appliance(s) place a high demand on the setup. But you should still replace it every 10 to 15 years to ensure that you're keeping your RV safe even if you have a premium regulator. The regulators we’ve looked at above are some of the best budget-friendly regulators around.
