From the page you connect one end of one of the pipes to your tap and
stuff the other end down the plug hole of the blocked drain. Turn on the
tap and jets of water squirt out the far end dislodging the crud.

This is fine provided the pipe has enough diameter left to carry the lumps
of dislodged crud...
