I just replaced two propane tanks at my local Giant, but when I connect either of them to my grill, I hear a hissing sound from where the regulator is connected to the tank.
At first, I assumed a faulty regulator, so I went out and bought a new one. Both tanks are still hissing quietly when I open the valve.

I tried the soap and water trick but didn't see any bubbles. Also, when I do run the grill, I don't get a very strong flame.

The hiss certainly sounds like it's coming from the area where the regulator is connected to the tank, but short of submerging the entire thing in water, I don't know how else to be 100% sure.

Is it possible that both tanks from Giant have a leak? I read about potential faulty o-rings on exchanged tanks, but it seems unlikely that the problem would be with both tanks.

Calling charbroil customer support only wasted 30 minutes of my time because they just wanted to sell me a regulator for $70.

Did you get the connection TIGHT?

You stated earlier that you were an older lady, and often they are not very strong, so I ask.

The soap bubble trick should have worked.

Get a local Boy Scout to look at it. They are the "good deed " people.

You must have me confused with someone else. I am not an old lady. Yes, the connection is tight.

 

[de-nagorg]

OK, if I am , I am.

I checked , that was not you, my mistake.

I apologize.

I will ask the obvious. When you installed the new tank and opened the valve, were the burners turned to the off position?
By the way, if the burners were off, and you heard a hissing sound, there is no way I would ignite the grill. There is a leak somewhere.

The burners are off when I hear the hissing sound. I should try this with a different tank, and if there's still a hiss, i'll just replace the whole grill. The cost to repair will probably be half of what a new grill will cost me.

It maybe you just need to replace the hose regulator assembly . It might be hard to get the right one unless it's a Weber or other higher end brand. The low ends may not have parts available. But then again a gas leak is a gas leak and it's dangerous. It doubt it is your tanks. The soap and bubble trick is pretty fool proof.

When you replaced the regulator, did you use the old plastic/metal fitting that goes to the tank or did the regulator come with that? The big plastic 'nut' that goes onto the tank is easy to crack if you overtighten it. Never use tools on that one.

If the regulator came with a hose that goes to the underside of the grill, that connection is a metal to metal fitting that has to be quite tight. You need to use two wrenches to get it tight enough.

You can also use your nose to detect leaks.

It's also possible that you have developed a leak on the underside, between where the regulator hooks up, and the burner valves.

Is the tank valve opened fully and backseated?
If not then the propane can/will leak around valve stem.

I've had propane cylinders leak at the acme fitting. specifically, the seal at the spring-loaded ball valve wasn't seating correctly with the grill's regulator. Bubbles did appear in my case. tried another cylinder and problem was gone.

If your soap/water mixture isn't correct, it may be difficult to get a bubble to form. I use Oatey brand bubbles, specifically made for the task. Even then, you have to tilt the connected regulator, such that the bubble solution fills the gap sufficiently, and then wait a minute or two, to see if a bubble forms....it may be a slow-growing bubble, if the leak is there.
