Studor/Air Admittance Valve
 

I need to put one in for a basement sink (yes, it's allowed by code in
my area)

Can someone tell me why I would want to buy the Studor brand for $25
when I can get the generic for $3? What am I missing? TIA.

The Studor is found to be more rleiable over time.
But the $3 one *does* work well.

Your pick.
