It can save you from the aggravating situation of running out of propane at the most inconvenient time, and it’s one of the simplest ways to know whether your propane tank is nearly empty.

In this post, we provide an answer to this question as well as numerous helpful suggestions and suggestions to assist you avoid running out of gas when you need it most.

Propane odor when tank is low – how does propane smell when it’s about to run out?

If you detect a distinct rotten egg/decaying animal odor, you’re almost probably dealing with a gas leak.

Remember that propane gas is odorless by nature, therefore firms add a non-toxic chemical called mercaptan (also known as thiol) to give it the distinctive “sulfur”/”rotten egg” scent.

A propane leak would be difficult to notice without it, and you would be in grave risk.

To put it another way, the foul-smelling odorant (which some people compare to strong garlic) is added to alert you to the presence of propane gas in the air after a leak has occurred.

Perhaps you’re wondering what generates the “skunk-like” propane odor when the tank is low.

Next, we’ll get to the answer…

When your propane tank is low, you’ll notice an unpleasant stench.

Ethyl-mercaptan, which is also added to natural gas for identical reasons, is now significantly heavier than propane.

As a result, as the tank starts to run low on fuel, it sinks to the bottom, causing the smell to become more prominent.

That’s because when your tank is low, either from regular use or because to a problem like a leak, more of it is released within the residence.

Essentially, the pungent stench fills the room’s low-lying regions initially, then moves upward as more propane is released.

The odor will eventually spread throughout your home, causing a variety of health problems such as dizziness, nausea, drowsiness, and confusion (at high concentrations).

Why letting your gas tank run out is a recipe for disaster

Forget about the discomfort of running out of propane at an inconvenient time; letting your propane tank go low might pose major safety risks.

Here’s a list of the bad things that could happen if you let your propane run out:

• Potential property damage- Without a doubt, the most expensive risk of your tank running out is property damage. Because there isn’t enough fuel to keep the house warm, pipes may freeze and explode. What’s the end result? A hefty repair bill!

• Propane leak- If a gas line/valve is open when propane is depleted, there’s a good chance your system will leak when it’s recharged.

• Corrosion—Due to the ease with which air and moisture can enter empty tanks, severe rust build-up inside your container is a possibility. While this may not seem like a significant deal, it makes it more difficult to detect a leak since the concentration of mercaptan in propane decreases. Furthermore, unless the rust is handled, it is likely to be permanent.

What to do if you smell “low propane in the tank”

When you detect the terrible “low-propane-in-tank” stink (that dreadful Sulphur/rotting cabbages/rotten eggs/decaying animal/smelly socks scent depending on your nostrils), you should take some vital steps.


Close all gas lines and valves right away.

The first step is to make sure that all of your propane tank’s common leakage points (primarily valves and gas lines) are shut tight.

Make contact with your propane provider.

Calling your local propane supplier for an emergency delivery should be your next action. In general, the technician will do a safety inspection first, which will include a leak check.

The propane company confirms that your line can withstand pressure for three minutes during a leak test (without any appliance running). This usually means that there isn’t any propane in the house.

Your container will be refilled once it has been certified that there is no lingering propane tank empty hazard.

Expect the service expert to perform further routine checks around the system to ensure it is leak-free and operating properly.

Frequently Asked Questions about Propane odor when tank is low

Is it common to get a whiff of propane near the tank?

In general, smelling a faint propane odor when you’re near the tank is nothing to be concerned about; it’s usual to smell a hint of propane from the activity at the regulator pressure relief valve/reducer as it vents to the air.

If the odor is particularly strong, though, you should be quite concerned.

Obviously, in such a case, the best plan of action is to contact a professional for aid in locating and repairing the leak.

What does it signify if you smell propane but there isn’t a leak?

Some users have reported smelling “rotten eggs,” however upon inspection by a licensed specialist, no leaks were discovered.

If this is occurring to you, we recommend having your tank replenished as soon as possible to see if the smell goes away; it could simply be an indication that your tank is running low.

What does propane smell like?

Last but not least,

The odor of “rotten eggs” can fade to the point where it is impossible to discern in the air.

When propane from underground pipes leaks and comes into touch with dirt, concrete, or other materials, the odorant is decreased by oxidation or absorption.

When it comes to tracking how much propane is left in the tank, it is therefore advisable to utilize propane detecting equipment like this rather than depending entirely on your sense of smell.
