How does LPG work?
LPG - Liquefied Petroleum Gas - is stored under pressure as a liquid in a gas bottle.
It turns back into a gas when you release some of the pressure in the gas bottle by turning on your appliance.
A regulator ensures a consistent pressure is safely delivered from the gas bottle to your appliances.
How many LPG gas bottles do I need?
With two gas bottles, you call to order as soon as one bottle is empty, while continuing to use the other bottle.
This gives you an uninterrupted supply of gas.
Please see What size & how many gas bottles do I need?
The following short video (2:37) explains why you need 2 bottles, how the changeover valves work and how to tell how much gas is left...
How are the gas bottles connected to my home?
The gas bottles are connected by tubing, known as “pigtails”, to a changeover valve and the changeover valve is connected to a regulator.
A gas line then runs from the regulator to your appliances.
The changeover valve controls which gas bottle is in use.
For more info, please see Home LPG Gas Regulators & Fittings
Who provides the regulator, changeover valve & “pigtails”?
The property owner engages a licensed gas fitter to install the gas regulator, changeover valve and the “pigtails”.
The gas fitter also connects the gas line from the regulator to your appliance(s).
These components and the appliances are the property of the homeowner.
Elgas owns and provides the gas bottles.
If you just moved into a home that already has LPG, all of this would have previously been done.
You just need to select from your LPG Gas Delivery Options.
How do I operate the gas bottle changeover switch valve?
Automatic changeover switch valves
These automatically switch from one gas bottle to another, when one is empty.
To do this, both gas bottle valves are left in the OPEN position.
Several types of automatic changeover valves are available.
All use a visual indicator to show you when a gas bottle is empty and it has switched over to the other gas bottle.
The indicator typically turns red when the first bottle is empty.
Do not touch or turn the indicator.
When it turns red, that’s your signal to call Elgas for a delivery.
We will replace the empty bottle with a full one and reset the indicator.
If you have an automatic changeover valve, you do not need to do anything.
However, you won't have the manual changeover process as a reminder to order more gas, so be sure to check your gas bottles regularly.
Manual changeover switch valves
1. Turn the hand wheel on the empty gas bottle OFF (clockwise).
2. You then move the changeover valve lever to point towards the other (full) gas bottle.
3. Turn the hand wheel on the full gas bottle ON (anti-clockwise).
4. Please remember to order a replacement gas bottle so you don’t run out.
5. Please note that, in the picture shown, the lever (blue) is pointing upwards just to make it more visible.
In actual use it would be set to the left or right.

How do I pay for my LPG gas?
Please see our Payment Options page for your various choices including Bpay and online payments.
How do I make sure I don't run out of gas?
Always order gas as soon as the first bottle runs out. Don't wait until the gas bottles are both empty or near empty. Follow this advice and you are virtually assured to never run out of gas.
Remember to check your gas bottles more often in cold weather or when you have additional house guests.
If you only have one gas bottle attached to your home, you may wish to consider adding a second gas bottle. This is particularly wise if you use it for hot water and/or heating.
Make sure we have your Mobile Number so you receive Gas Check Alerts™ by Text (SMS).
Be certain to tell us if you install additional appliances, especially if you are on automatic tanker delivery, so we can adjust your delivery schedule.
How do I know how much gas is left?
Carefully pour a cup of hot water down the side of the bottle and a line of condensation should appear at the level of the remaining gas.
If no line is apparent, you can also wait a few seconds and run your hand down the cylinder.
It will feel cool to the touch at the level of the gas.
If you see no line and feel no difference in temperature, chances are the bottle is empty.
Remember to always use care with the hot water.
Also, please be aware that gas bottles are designed to be full at 80% or just over 3/4.
The bottles are oversized so you get the full measure of gas.
The unfilled space, called "ullage", allows for the natural expansion of the gas during warmer temperatures.
How often should I check my gas bottles?
That all depends on the type and number of appliances, your climate, the number of people in your home and how often you use the appliances.
The following maximum time intervals are based on averages and assume that you are starting with full gas bottles:
Cooking only - Every 9 to 12 months
Hot water only - Every 2-3 months depending on climate and the number of people in your home.
Heater only - Every month during heating season or more often with large or multiple units and in colder climates.
Combinations of the above - Every month or more often during heating season with large or multiple units and in colder climates.
Or whenever you receive a Gas Check Alert from us on your mobile telephone
NOTE: You do NOT need to check gas bottles if you choose our Automatic Tanker Delivery
How long should a gas bottle last?
What if the gas isn’t working?
Check to make sure the active gas bottle is turned on.
The active gas bottle is the one pointed to by the changeover valve.
Check to see if either gas bottle has any gas left, using the hot water test.
If so, you may need to switch to the full gas bottle with the changeover valve.
If both bottles are empty, please contact us for a gas delivery and make sure you tell us you need two gas bottles.
What if there is a gas leak?
In the unlikely event that you have a gas leak, turn off the cylinder valve(s) by rotating clockwise.
You should also call the Elgas emergency response number on 1800 819 783.
As an added precaution, make sure the area is well ventilated to disperse any gas, and remove or turn off all flames and other sources of ignition.
