Description
EFB- Externally Flanged Base Tank
EFB Tanks are to be installed where there is adequate access to the base and sides of the Tank to allow for the installation from outside the Tank. They can be fully drained quickly and without pumps. A clearance space of a minimum of 500mm is required on all sides and there must be sufficient headroom above the Tank for opening the man way cover. The base fixings are only accessible from the underside of the Tank, and must be raised on Concrete Piers/ Goalposts or a combination of one of these and RSJs.
