Pour the sand in slowly, distributing it evenly around the pipe.
Make sure that the pipe does not come out of its housing.
When you have finished, remove the flange and keep it for the

the edge of the container.
Put the selector valve back in place. Re-connect the pipes which
were previously removed and then make the connections to the
ground drainage point (also connect the total drainage valve of
the filter, located at the bottom of it, as shown in the figure).
