If you hear a distinct whistling noise when you switch on your gas fire pit, you’ll need to figure out what’s wrong. Fortunately, the repairs are straightforward, although you may want expert assistance to finish the task.

Keep an eye on your flex line.

When it comes to whistling sounds, the flex line is usually always at blame. Flex lines are made of a variety of materials to withstand the strain, but some are better than others when it comes to releasing trapped pressure. 

The whistling noise is most likely caused by built-up pressure in your flex line. As a result, it’s strongly recommended that you always get a whistle-free flex line, and yes, they are correctly titled.

Consider a Flex Line with No Whistles.

Whistle-free flex lines are made with the right materials to prevent pressure buildup in the line, also known as bottlenecking. They make certain that the pressure is evenly distributed throughout the line.

Check the Flex Line for Kinks

Kinks and bends in the flex line are another common source of whistling in the flex line. These kinks and bends cause ‘bottlenecking’ at particular spots, which means that pressure is concentrated in one spot. This causes a lot of vibration, which sounds like a whistling noise. 

Take a close check at the flex line to be sure a kink isn’t the source of your whistling. From start to completion, your flex line should be smooth and straight. If you find any bends or kinks, particularly those at a 90-degree angle, straighten them out right away.

If your flex line must curve at any point, you should use hard piping or specialist fittings to assist the flex line manage the bends without bottlenecking. 

Select a Flex Line with a Larger Diameter.

Whistling may also be caused by a flex line that is overly thin and narrow. Pressure has less space to pass via a flex line with a smaller diameter. This might generate a buildup in the line, resulting in the whistling sound.

If you believe you have a flex line that is just too tiny for the load, you should replace it right away. Your new flex line should have a larger diameter to guarantee that there is no pressure buildup from start to finish. 

For a larger diameter, the Stanbroil 12″ X 24″ Non-Whistle Flexible Flex Line is a perfect option. This flex line not only provides flexibility and endurance, but it also features a staggered pitch to prevent whistling sounds. Simply stated, it’s the all-in-one flex line constructed of stainless steel, which means it’ll last a lifetime with your fire pit.

Problems with Gas Supply

If you’ve completely inspected your flex line and are still experiencing a whistling sound, you may need to check your gas supply.

Gas Species Water Column Pressure
Natural Gas is a kind of fuel that is used In the range of 3.5″ to 7″
Propane Approximately 8″ to 11″ 

*W.C., or Water Column, is a unit of measurement similar to PSI.

*It’s best to be on the upper side of these measures for a more powerful blaze in your fire pit.
