I use a lot of PVC piping in my fishfarm however for gutter applications 
its not ideal. PVC to be blunt is not very good in full sun exposure UV 
resistant gets brittle and is prohibitively expensive. Well casings are 
schedule 80 by the way not 40.
There is UV resistant but well casing typically is not. A note on 'UV
resistant' PVC it will get brittle and doesn't last forever.I double
wall it when exposed and paint inner pipe black to shield it. Simply use 
larger size over smaller...
ABS is cheaper and also is unacceptable: doesn't last too thin also.
For Downspout situations I use large 2 and 1/2 inch by 4 inch vinyl
available available at HD or Lowess Use 'silicone sealant' for all
fittings and it should be well fastened with the standard strapping
system readily available with this type of gutter down spout system. If
you want to secure it further use stainless steel hardware and screws.
A converter plastic adapter(also in Store) will resize it to fit round 3 
or 4 inch size for underground PVC pipe run. Divertors made of PVC are
well.. inadequate to be blunt and expensive! better way is do use food
grade barrel (Greek Olive barrels of approx 30 some odd gallon have nice 
lids and are very nice. Bury theses inline and put drains with smaller 
PVC at bottom and drain to lower elevation (or directed to buried 
central barrel) where it the dirty water can be pumped off with one pump 
for garden use. Use 'floating RV swim ring float system' rise even if 
barrel is full way if housing of larger bucket is siliconed on top of 
olive barrel top above ground.to allow the ring and pump float. Use a 
runoff opening to drain overflow on ground at that point(cut into side 
of overflow top bucket housing.

Vinyl is easy to work with and isn't unsightly like expensive hard to
fasten cheaply PVC pipe. Silicone is safe to drink (aquarium grade or if 
you aren't drinking it use GE 50 year guarantee GE product has mold
inhibitor in that product
