What is My Propane Tank Making Noises?

We often get asked, “Why is my propane tank making noises?” All propane tanks consist of the same components, regardless of whether its a portable tank or a full-size home tank. Overuse and aging can cause your tank to make noises. These noises will either be coming from the tank itself or the gas line. Unusual noises tend to be a bad sign, so if you believe there may be a problem with your propane tank, read this article to determine what the noise indicates and contact us at Texas Propane.

Why is My Propane Tank Making Noises?

Humming or Gurgling Sounds

Your tank may have been overfilled if you hear a gurgling rumble or humming noise when you turn on the gas. This means the tank will be experiencing excess pressure. As a result, this puts strain on the regulator and reduces outflow from the tank. It is likely that your tank has been overfilled if you are experiencing the following:

• weak flames
• low heat
• discoloring of the pilot lights

Another source which can cause humming is trapped air or the vibrating of the regulator. If you are unsure what is causing these noises, or if you believe your propane tank has been overfilled, do not try to drain it yourself as this can be highly dangerous. Contact a professional instead.

Knocking Sounds

A knocking sound can be an indicator of danger. When you hear knocking come from your propane gas tank after it has been turned on, it usually means that mixture of gas and air is uneven. You can check the flames to establish if this the case — blue with a yellow tip indicates the correct measure, but if they are yellow or white, you should contact a technician.

Hissing Sounds

The most common sound people hear from propane tanks is hissing. This sound is usually a sign of a gas leak, and therefore means that you should turn off the tank immediately and contact a professional.
