The Sound of a Safe Heating Oil Delivery
If your oil tank is located in your basement and you’re home when our driver makes his delivery, you’re going to hear a whistling noise as your tank starts to fill up. This is perfectly normal. Here’s why this happens.
Besides your tank, your heating oil storage system includes the fill pipe, vent pipe and vent alarm. After our driver arrives, he connects the hose from his oil truck to the fill pipe and starts releasing the oil. As oil flows into the tank, air is pushed back out. As the air goes through the vent alarm–located between your tank and vent pipe–it makes a whistling sound. When the whistling stops, the tank is just about full.
Since your basement tank is out of sight from our driver, the vent alarm prevents overfilling and the possibility of a spill. Safety codes do not allow us to deliver your fuel if the vent alarm is not working.
Speaking of safety codes, here are a few more things you should know about your oil piping:
- The vent pipe should be at least 1.25 inches in diameter. A narrow diameter allows excessive pressure to build up inside the tank during filling, which can cause a tank rupture.
- Your piping should be made of iron, steel, or brass. Pipes made from PVC need to be replaced because they are more likely to crack when tanks are being filled.
- It is the homeowner’s responsibility to properly maintain fuel tanks and all associated piping.
