What Makes That Whistling Sound During Oil Deliveries?

oil fill pipeFor homeowners who have oil heating systems in your home, you may be wondering what that whistling sound is that you hear when you have oil delivered. The good news is that this sound is entirely normal and nothing that should cause any concern. Since your oil tank cannot communicate with words, the sounds you hear are actually vitally important to your safety and the health of your oil tank.

What Happens During an Oil Delivery

When you contact Tragar Express to deliver our Biofuel® oil to your home, an oil delivery driver will arrive with an oil truck. The oil truck driver will then connect their oil truck’s hose to your oil tank’s fill pipe to start filling the tank with oil, as explained by DiscoverHeatingOilMass.com. As your oil tank is filling up with oil, it produces a whistling sound, but why?

What Your Oil Tank Is Telling You

When your oil tank is receiving an oil delivery, something interesting occurs. Along with your tank’s fill pipe, another essential part of your oil tank is its vent alarm. McAllisterEnergy.com explains that air from the empty tank space is pushed out as oil is entering into your tank. The air then passes through the tank’s vent alarm which produces that whistling sound. The vent alarm will continue to whistle until the tank is full, which helps prevent the driver from overfilling your oil tank.

The alarm is critical to maintaining the balance of air and oil in your tank. A standard residential oil tank has a 275-gallon capacity, but it is considered full when it has 225 gallons. The vent alarm helps to ensure this.
