I dunno except for my local farm and feed store, they carry a great
selection of PVC pipe, and the brand name streamline is like paper,
its got to be half the thickness of schedule 40.....Why anyone would
want that thin of walled pipe for domestic water use is beyond me,
however in an aquarium it would be perfect.

I see standard schedule 40 pipes in every home-improvement store.
But they are designed for very high pressures (450PSI for 1" pipe).

I have noticed the pipes used in commercialy available overflow
kits (like Oceanic/AllGlass MEGAFLOW) are very thin walled pipes...
For example, their 3/4" OD pipe has 0.950" ID end wall thickness
less than 0.060" - compare to:

SCH40 3/4", ID: 0.824", wall thickness: 0.113"
SCH40 1/8", wall thickness: 0.068" - you got the picture.

The bottom line is that their 3/4" pipe has a similar inside
diameter to a standard SCH40 1" pipe occupying less space
giving also much less resistance to water flow...

All is great, and I would prefer using such pipes over SCH40,
but WHERE CAN I GET SUCH THIN WALLED 1" or 3/4" PVC PIPES ?

Anybody knows?
