http://www.piscine.co/spareparts/1/1007069/9/1008293/filtre-lamine-side-avant-2005/ I have emptied the filter of sand in order to fix a broken lateral. At the bottom of the sand was a thin white flexible tube about 50cms long. It is attached at one end to the lateral assembly but not attached at the other end. I think it might be the tube shown running vertically to the left of the inlet and outlet pipes in the attached diagram (see included web address for diagram). The diagram is not clear as to the placement/fixing of the tube at the top. Any ideas as to how this tube should be fixed?
