I think you are having problems trying to match solid DWV PVC pipe with
perforated Sewer pipe, they are different but a little looking will find
couplings to match the two pipes together along with specialized couplings
to match virtually all common pipes with other commonly used pipe types.

I was following the advice in the home depot outdoor projects book about
moving the water from my gutter down-spout to someplace farther away.

But I'm confused on one point.

Should I be using the PVC pipe with holes in it (at 4 and 8 o'clock) such
that the water disperses along 10' of it and the rest ends in a sistern,
or should I be transporting part of the way in solid PVC to keep even
small seepage away from the house?

The only problem is that the non-hole PVC doesn't fit the adapters needed
to connect the downspount--PVC. A silly thing really, looks like a
conflict in inner vs. outter diameter specs.

So should it be this:

*Downspout--Adapter--(connected somehow)10' Solid PVC--Sistern*

or

*Downspout--Adapter--(connected somehow)4' Solid PVC--10' drainage
PVC--Sistern*

or just the easiest

*Downspout--Adapter---(connects redily)10' drainage PVC--Sistern.*

And *HOW BIG* should the sistern be? The ground fill is highly rocky
(good) but this downspout manages all the water for half the main roof,
half the baywindow roof, and the porch roof.
