Is it possible to shorten the side inlets of a Vieser One vertical floor drain if they make the installation more difficult?

If the side inlets are not needed and they cause problems with the installation, it is possible to shorten them or to saw them off (attention must be paid not to make a hole at the inlet). You have to remove the plastic cover from the side inlets, if they are used. In this case it is not necessary, since the side inlets are not used.
