first i would recommned get rid of the ficus they not only invade
drain pipes but can get into the foundations of homes and cause
the best method i know of keeping roots out of drain pipes is to use
those poly type pipes that get glued together, they are more flexible
to ahndel some movement of the soil and unless they actually crack
roots can't get in, so long as the joints are glued properly.
that perforated pipe for yard drainage is a purpose made pipe, and is
sued for draining poorly drained areas of yard so needs to be
perforated, if you ahve a look at our frenchdrain/agricultural drain
page you will get an idea of how it should be used.
but ther again if ther are any trees around with invasive root systems
and fucus are at the top of the list these trees will clog up the
drain in no time at all.
you can join into an existing drain pipe runs, but you do need to cut
a section out and fit in a 'T' or a 'Y' junction and this too needs to
then be sealed properly or you are inviting trouble from tree roots &
leakages later if the ground moves.
no matter what you do be sure to lay/re-lay the new work into bedding
sand to minimise possible damage from soil movements.
we ahve pl;umbing stores ove here or builders wharehouses they will
sell you or should do exactly everything you want and they should also
give some advice.
keep us informed
