We have just published our new 3D Holding Tank Layouts which we think are much easier to understand than our previous versions. They still cover above and below  waterline installations with added notes.

They can be viewed with the parts legend by just clicking the photo or a full 360 degree animation can be downloaded. If the loop or repeat button is switched on in your player then the layout will just carry on rotating.
