A gas regulator is an item which allows you to regulate just the right amount of pressure to adequately control the gas feed and flow from your gas bottle to your designated gas appliances.
With many caravanners using gas for heaters, gas stoves and BBQs on their travels, a standard gas regulator does the vital job of transporting this gas safely.
However, if you often continually find yourself running out of gas at the most inconvenient of times and places, you may just want to look at those regulator models that offer a level gauge.
Not only are these gauges great for safety, alerting you to any potential gas leaks, but they also work at offering you a better idea of the level of gas you have left in your bottle, making sure that you’re never caught short again!
It’s also worth paying extra attention to the exact type of gas bottle or tank that your chosen caravan gas regulator works with. This is because there are certain regulators for propane gas and specific ones for butane gas.

Caravan Gas Regulator Problems
Although it may never happen to you, it is worth being aware of the most common caravan gas regulator problems you could face.
Iced Up Regulator
Gas regulators you use in your caravan can freeze up, even at temperatures close to freezing. At first, the flow of gas is greatly reduced and then totally stops. Why? Because LPG consists of a very small percentage of water and once the temperature drops to 0-degrees Celsius, minuscule ice crystals start to form. Then, when you withdraw gas, the ice crystals make their way into the regular and freeze it up.
Oiled up Gas Regulator
It’s entirely possible for your gas regulator to become oiled up and this is usually the result of contamination from the aerosol gas in vehicle tanks and refillable cylinders, such as paraffin, olefin and other common compounds of hydrocarbon that make their way into your caravan’s LPG through the logistics chain. You won’t see any difference between contaminated and clean gas when you buy it. When the particles of oil are taken back into the flow of gas, the can build up inside the valves, pipes, hoses and can cause a caravan gas regulator blockage.
If the oiling up causes the regulator to become damaged and cannot function properly, it needs to be replaced completely.
How to Test a Caravan Gas Regulator
Regularly checking and replacing your caravan gas regulator is part of general caravan maintenance. Though gas regulators are built to last a long time, there are many ways they can become faulty. The easiest solution is replacing the caravan gas regulator, the pigtails and the gas bottle itself.
Fortunately, checking your caravan gas regulator is easy nowadays. There are Test points that you can fit unto your gas regulator to check whether it is functioning properly. These Test Points are even mandatory in many places worldwide with some Test Points already installed on your gas regulator.
Testing the caravan gas regulator with the Test Point is simple. Open up the Test Point screw and check how much gas is flowing through.
Is too much gas flowing through? Then the gas regulator is damaged so you need to replace your caravan gas regulator.
Is there barely any gas flowing through? This indicates a blockage in either the regulator itself or the pigtails.
