Holes down - always!!!!!! You are maintaining a hole through the
dirt, you want the water to enter the hole as soon as possible.
You do NOT want to have a pipe full of water. The idea is to move
the water to somewhere else, not to let it into the soil/gravel.
The sock and/or gravel is to try to keep dirt from choking the
holes. Ground cloth on top of the gravel is to try to keep the
gravel from getting choked.

Most of the crinkle wall (my term) black plastic product is done
with slots all around the pipe.

I'm installing a French drain that will also be accepting water
from
several of my gutters. I have installed gutter gaurds on all of
the
gutters, so that should eliminate large debris from clogging up
the
drain, but a certain amount of gutter sludge is bound to make
its way
into the drain over time.

So, I'm thinking that installing the drain with holes-down will
just
dump that sludge into the gravel below the pipe (or into the
pipe sock),
where it will build up, whereas a holes-up situation would allow
the sludge to remain in the pipe until it's eventually flushed
out.

Does that sound logical?

If "sludge" washes down from the gutters, then you want it to keep on
going....just my instinct, not expertise. Holes down to allow better
emptying of the drains into the gravel would seem to be the better
choice, as it would take fine sludge with it into the gravel. With
holes up, it would seem like the drains would fill with water and allow
silt to settle inside the drain pipe.

I would do research on this, my french drain is about 90 yrs old and
still flowing fast but ive heard of instalations clogging in 10 years
that were not done as best as can be done. Gravel surrounding the pipe
is a must and hole down is how I did my last tile system, the sock
will probably fail with holes up.

My understanding is that gutter drains should be solid and kept
separate from perforated French drains. If the two are combined, then
if the drain plugs up from gutter debris, the gutter water gets dumped
into precisely the ground area you are trying to drain.

So, I'm thinking that installing the drain with holes-down will just
dump that sludge into the gravel below the pipe (or into the pipe
sock), where it will build up, whereas a holes-up situation would
allow the sludge to remain in the pipe until it's eventually flushed

If you are trying to collect surface water that percolates downward,
you put the holes up. If you are trying to collect ground water
rising upward (i.e. a foundation drain), then you put the holes down.

Cheers,
Wayne

1. Do not connect your gutters to your french drain system.

2. French drain systems always have the pipe holes on the bottom to
start accepting water at even the lowest levels in the trench.

These gutter guards work very well at keeping debris out of the gutters,
they just have to be swept off from above every once and a while, or the
water will run right over them. I know
that blackish sludge and shingle grit will eventually make its way down
the spout, so that's all I'm concerned about.

The intersections along the drain are only about 40 feet apart at most, with each
gutter connected to the main drain by a Y fitting, so a snake would be
guided downhill at each connection, which should make snaking each section
easy, if were ever needed.

If you are trying to collect surface water that percolates downward,
you put the holes up. If you are trying to collect ground water
rising upward (i.e. a foundation drain), then you put the holes down.

Surface water is my only real concern, as the land was poorly graded.

PVC pipe is dirt cheap run seperate lines, ideally the lines should
drain well away from home to daylight.

If your installing exterior french drains it should be below footer
level......
