What is a Tiger Loop?
As of April 2012, all outdoor fule tanks need to be made of fiberglass or composite. Also, these tanks need to be "top fed", which means that the fuel oil no longer comes out of the bottom of the tank, but the top. This setup can cause burner malfunction because of the negative pressure in the fuel line. This negative pressure can cause minute air bubbles to be released from the fuel and they will eventually end up in the burner pump causing the burner to fail. In order to prevent his from happening, an apparatus called a "tiger loop" must be installed on the system. A tiger loop enables the system to dissipate the air in the oil into the atmosphere, preventing a build up of air in the pump for trouble free operation. If your system includes and oil fired hot water heater, this too can be plumbed into the tiger loop system.

In order to save money some people are in the market to purchase a used fiberglass tank and have it transported and installed at another location. Here are some things you should know in order to avoid problems down the road.

Yes. In order to keep an inspector-installer license current, it is necessary to provide proof of insurance (environmental and personal liability insurance) to the licensing agency (PEI Dept of Environment.). Every inspector-installer should be able to produce a proof of insurance document upon request.
