The translucent ones are most likely styrene and sold for landscape and
architectural drainage pipes buried in the ground. Hardly an environment
where leaks are a problem, since the pipe often has holes every few inches
anyway.

I'd go with real PVC, designed to take some pressure. Even the DWV ABS
stuff, although it is nice and flat on the end caps is actually a foamed
core composite and not very strong, and not designed to much pressure
(that's why you have vent (the V in DWV) stacks on your drains (the D in
DWV) that carry the waste (the W..) from your sinks and toilets.
