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.
