Why Is My Propane Grill Tank Making Hissing Noises?

valve clockwise to the off position. If you are unable to turn it off, leave the area and call your local fire department. In both cases, you’ll need to have a qualified service technician check out your grill for leaks. Generally, a humming sound without the smell of gas is normal.
Test for Leaks
If you suspect there may be a gas leak from the hose or connectors, and it is safe to do so, you can use a simple test to determine the leak. Prepare a solution of equal parts water and liquid dish soap. Ensure the cylinder valve on the gas tank is closed. Either pour into a spray bottle or use a grilling brush to apply the solution along the gas hose and connections. Open the cylinder valve, and examine the hose and gas line connections for soap bubbles. These bubbles indicate a leak. If you see bubbles, turn off the cylinder valve and replace or repair the area that is leaking by contacting a qualified service technician.
The bleeder valve, also called a fixed liquid level gauge, is typically opened by the delivery person when a tank is filled with propane. If the bleeder valve is not closed entirely, or was blocked from the inside when closed but is now cleared, this may be causing the noise. To fix this, turn the bleeder valve clockwise to ensure it is closed and stop the flow of gas.
Cool Down Your Tank
Propane tanks can build up extra pressure when they overheat due to expanding liquid in the tank. On extra hot days, the safety relief valve may open to release built up pressure in the tank. The pressure will remove the protective cap, opening the relief valve. It is crucial to not look into the relief valve or tap it with anything. You want to avoid the relief valve opening all the way. The easiest fix is to spray to tank with a water hose to cool it down, causing the relief valve to close entirely.
If you’ve ever hooked up a new propane gas tank and heard a faint hissing sound, your first thought is likely to be, uh oh—there’s a gas leak somewhere. Well, this may be true. Propane tanks will often hint at a slight leak by making a hissing sound, which gets louder as you get closer to the tank. But, there are a few other possible reasons your new tank isn’t working as expected. So next time you hear the hissing and suspect you might have a leaking propane tank on your hands, follow these tips to determine the cause.
If you hear a hissing noise, tune into your sense of smell too. If you smell gas, and you’ve checked the situation is safe, turn the cylinder
