An example of this could be elbows and connecting pieces (T-junctions), or junctions in which more than one pipe merges together (water used for multiple distinct purposes at one point may merge together in a large outflow pipe). Directly buried fuel supply pipes should be protected against the risk of accidental damage caused by digging. A typical gravity supply would consist of a bottom outlet fuel storage tank positioned above the height of the burner.

OTHER: Other compounds have their own labels, including compressed air (light blue), steam (silver-grey), drainage pipes (black), electrical conduits (orange), acids (violet), and more.For satisfactory performance, it is critical that fuel supply pipes used with sub-gravity systems are correctly sized. Underground Warning Tape for marking buried services including underground cables and pipes - premium grade underground warning tape with ENATS 12-23 approval for cable and pipe marking. Centritile cable warning and protection rolls (Tape Tile) are rolled out into the trench for quick and easy protection of low voltage, high voltage (up to 11kV), street lighting, telecoms and fibre optic cables - also suitable for underground gas and water pipe protection. Fuel supply pipework between the tank and the burner which is hidden or inaccessible should be pressure tested at least every five years to confirm its integrity.

Domestic fuel supply pipes are usually made of plastic-coated soft copper tubing that can be easily manipulated. It’s therefore important to do what you can to stay on the right side of the law and using the right equipment can certainly help.However, to reflect that a renewable liquid fuel, such as HVO may soon be available (see our future heating section) we have used the term liquid fuel in this guide to include both oil and low carbon liquid fuels. Gravity supply systems are arranged so that the pressure of the fuel in the tank pushes the fuel along the pipe to feed the burner at the appliance. Health and safety can be a tricky issue for businesses to deal with, with a whole host of legislation in place.
