When Pressurizing an Empty Propane Tank What Needs to Be Switched Off and on Again

Does your propane tank go along shutting off before y'all even get a take chances to put it to work?  Has your frustration level reached astronomical heights because you've been unable to grill?

Are you set up to throw in the towel and become buy a new gas grill?

Well don't.  Not nonetheless.

But earlier getting as well much further, this article isn't just virtually gas grills.  It's about propane, propane tanks, and annihilation you might apply propane for.

What tin can that include?  Grills, as already noted.  Only in that location'south likewise propane fire pits, stoves, ranges, fireplaces, and even water heaters.

The point is, a lot of people employ propane for a wide variety of appliances. This is especially true in more rural areas where natural gas may not be available and a homeowner still prefers to use gas for their appliances.

The bottom line is, regardless of what kind of propane appliances you lot have, if you have a propane tank that keeps shutting off, yous need to do some troubleshooting and detect a quick fix.

Below you'll discover some possible reasons why your tank is shutting off and the fix that'southward right for you.

i. Let's Presume Y'all have Propane in the Tank

This isn't meant to be insulting and please don't take information technology that fashion.  Believe it or not, a lot of problem people take when it comes to propane issues is non realizing the tank is empty or virtually empty.

When it comes to propane use in any propane appliance, it'due south non only about how total the tank is, it'south about propane menses and pressure.  If y'all don't have enough gas in the tank, you're not going to be able to build up enough pressure to go good ignition.

Best case, you may get flame for a little while but more than likely it will sputter for a bit and so shut off.

Again, though, we'll assume the gas tank is full or close to full.  However, it never hurts to double cheque.

It seems quite obvious, but in many cases, checking that in that location is actually propane in the tank may exist the solution to your problem.

ii. It's All About Safety

More than than probable, if you have a full tank of gas and you're having problems with the tank shutting off, you lot're probably dealing with a condom characteristic.

Notice we didn't say safety issue.  Well, if the safety feature is working by preventing farther gas from flowing, there is a safe business organization, from a technical betoken of view, that has activated the safety feature.

Nonetheless, you're more than than probable dealing with an issue that'southward easily corrected. *Knock on wood*

Call up, condom when it comes to propane appliances isn't only most the burn down end.  Information technology'south about preventing things from going BOOM. That means preventing the introduction of combustible gas into the equation if there is a safety event detected anywhere that gas can reach.

And so, what safety problems are y'all dealing with if your propane tank is shutting off?

3. Your Control Valves are Open

Ah, control valves.

Permit's go dorsum to the gas grill to illustrate how this could exist a trouble.  If you hook up a full propane tank to your grill and open up up your shutoff valve to your tank without checking to make sure your control valves on the grill are airtight, you may be dealing with a Lock Out.

What's happening is the safety mechanism (ordinarily a cheque valve) in the propane regulator on the tank side is detecting faster than normal gas period. This could be due to a leak, a problem with your regulator, or one or more than of your control valves on your grill are open already.

Then, audit to see if your control valves are open.  If they are, so that'south probably the reason your tank is shutting off.

4. Y'all're Opening Your Control Valve As well Fast

If you're opening the command valve too fast or open information technology also wide instead of 1 turn, you're creating a situation where the gas is flowing too fast at one time.

Ideally, you'd accept the control valve airtight when yous slowly open the shutoff valve at the tank.  After plenty pressure has congenital up in the supply line, you'd ideally open up the control valve plenty to hear and smell flow earlier igniting the propane.

If you open don't allow enough pressure level to build upwards or open the control valve too fast or too wide, your flow rate may be greater than necessary, which trigger the regulator to go into condom style and lock the tank out.

Call back, the propane regulator's task is to regulate. If gas is moving too fast, the regulator will slow it downwards or shut it downwards completely (if it's performance as designed).

This tin can besides happen if you open up more than i command valve at a time (as in the example of a gas grill).  Get slow and open your valves one at a fourth dimension.

five. You Have a Leak

Let'due south talk about leaks for a 2nd.

A leak will definitely touch on your gas flow rate.  If at that place is a leak, your tank should Lock Out.

How will you lot know if you have a leak?  Well, if you odour gas fifty-fifty if your command valves are closed there's a practiced hazard you have a leak.

Even so, rust build up within a propane tank tin temper the smell of gas.  Another manner to check is to take soapy h2o and spray information technology lightly in areas where gas can leak. If you encounter bubbling where you lot sprayed, in that location's your leak.

6. Your Regulator is Having Issues

If you've got a problem with your propane regulator, this can also affect the flow of propane.  It may not atomic number 82 to a Lock Out.  Instead, yous may cease up playing with the shutoff valve if you notice an issue with how much gas you're getting.

In other words, if you're opening your propane valve more and more to increase the flow of gas, your regulator may need troubleshooting and replacing. Information technology's not your task to take the place of the regulator.  If you're throttling that valve, that'south essentially what y'all're doing.

If your regulator isn't Locking Out even as y'all constantly throttle the shutoff valve, and then you've got another indication your regulator needs piece of work or replacement.

The purpose of the regulator is to control the flow of gas vapor from the container to the burner tip.

7. Quick Fixes

Now that the possible bug have been covered, allow'southward review some quick fixes you can attempt to come across if you lot've corrected your propane tank shutoff problem.

1. Ensure in that location's gas in the tank.  Again, information technology never hurts to double check.
2. Check the Control Valves.  Ensure they're close earlier opening your propane tank shut off valve.
3. Open up your Shutoff and Control Valves slowly and ane at a time.  Before opening your control valves, ensure your shutoff valve is open and has been given a few moments to pressurize the supply lines. During this footstep, you tin can also listen for whatsoever odd noises like hissing or smell for gas.
4. Check and ostend leaks.  If you practise hear hissing or olfactory property gas, so it's fourth dimension to check for leaks.  Remember, soapy water sprayed in prime leak areas is the easiest detection method.  Repair/supplant parts that are leaking. Practice not use the appliance until then.
5. Replace your regulator.  If you're dealing with a faulty regulator and you've substantially go the regulator past manually throttling valves, replace it.

eight. Steps to Correct a Lock Out

At present let's return to the topic of condom.  Or rather, let's take a wait at the steps to take to right or reset your propane tank if you lot're experiencing a Lock Out.

If your gas tank did indeed enter a Lock Out status and if you don't have any leaks and your regulator is fine, at that place are some like shooting fish in a barrel steps to accept to reset your tank from Lock Out.

1. Ensure the command valve(s) and shutoff valve at the tank are closed.
2. Disconnect the propane tank and let sit for at least 30 seconds.  While waiting, you may here a click.  That's the internal check valve in the regulator that locked your tank out resetting.
3. Reconnect the propane tank.
4. Slowly open the propane tank shutoff valve (1 full rotation should be enough to start).
5. Slowly open your command valve.
6. Ignite.
7. Open whatever other control valves as necessary.

On a side note, if you lot continue to experience a safety Lock Out, yous may exist dealing with another situation that isn't related to your propane tank's regulator, leaks, or valves being open that shouldn't be.

No, you may need to take into consideration external temperatures. This is true not just if it's hot outside merely also how much directly sunlight your propane tank may be exposed to.

If you're dealing with a hot solar day or an intense sun, your propane tank will go hot.  That estrus can cause the propane in the tank to estrus up, expand, and a lead to more pressure than normal in the tank.

When the shutoff valve is opened, even if it's opened slowly, that already built-up excess pressure volition lead to the gas flowing faster than normal as it seeks the path of to the lowest degree resistance. Which may cause a Lock Out.

The steps to right this are the same.  Yet, until the pressure in the tank normalizes, it may take repeating the steps above several times before the Lock Out is completely reset. At this bespeak, you're basically "burping" the tank to normal force per unit area.

Conclusion

If y'all've got propane appliances and a propane tank that keeps shutting off yous accept, essentially, propane appliances that are non currently functional.

That doesn't hateful you need to go out and replace your propane appliances.  However, there is some troubleshooting you'll need to practise to hopefully place the issue and set up information technology quickly to prevent further interruption to your appliance'due south performance.
