She don't like, she don't like, she don't like,..... PROPANE

2nd time this has happened to me. I buy an exchange tank at the gas station, and the gas won't flow!!

Now I have to lug it back for another one.

Any idea why this happens? The tank weighs out as full.......But no flow!

You got me there, I have never had a problem with tanks. But I normally get them at Walmart. It is closer to my house, only reason. That sucks dude!

As you open the valve on your propane bottle, very very gently just crack it open, then slowly advance the knob until it's fully open.

Sometimes the safety valve inside will restrict the flow if it is opened too much at once.

My BBQ does this occasionally. In my case, it is the screw-on connector to the propane tank itself. If unscrew it and then screw it back in, it works for me. It only happens when I first hook up the tank. I think it might be a pressure valve or something.

Yep. Also - if you leave the external valve open after your last brew BEFORE you open the tank valve, this will also cause the tank to not flow.

That's exactly it. Make sure to always close the external knob first before you close the internal valve. All you need to do now is to close it one time properly, and then it should work again.

To summarize the -credible- responses. When you're running the standard propane burner, you're dealing with two valves. There's the valve on top of the tank, then there's a valve next to the regulator in the propane line leading to the burner.

What you're doing is engaging a safety feature built in to the current generation of OPD valve tanks. To avoid this, you must proceed as outlined in previous posts.

1. When you start, both valves should be tightly shut.

2. If it isn't on, screw the plastic collar on the propane line onto the tank valve.

3. Open the tank valve completely.

4. Crack the inline valve, light the gas, and adjust to the flame height desired.

To avoid future issues, just develop the habit of completely closing both valves when you're done, and next time remember to open the tank valve first.

Actually, here's how to do it properly.

1. Hook up the regulator to the tank

2. With the appliance valve closed, open the tank vavle slowly.

3. Now open the appliance valve and ignite the burner.

4. To shut down, cloese the tank valve first (this will seem counter intuitive but it's the right way to do it)

5. Lastly, close the appliance valve.

Repeat the same procedure next time. Should you encounter the problem again, close the tank valve and open the appliance valve to equalize the pressure, then begin once again from step one.


There are two safety features built in to the common regulators. One is the overfill protection device inside the tank (I think it also functions as s tip over shut off, but I'm not certain if that was the intent of the design or simply incidental to it). The second safety feature is built into the regulator/connector and is designed to restrict the gas flow in the event of a ruptured or cut gas line. Some gas will often continue to flow, but at a greatly reduced rate. This feature is sometimes referrred to as a an anti-surge valve or surge protection device. Not all connectors/regulators have this feature, but most of the common ones we use do. The ones that do not are colored green and are designed for high flow demand appliances. The common ones are colored black. I am not an expert on this stuff, so as usual, YMMV and proceed at your own peril. Just what I have picked up on over the years. Hope it is of some help. The problems will typically vanish if you adhere to the above. Been there as they say.

Exactly wrong. That's why he's having problems now. First shut off the appliance valve, then shut off the main valve.
