plumbing from Lowes - really not as good?
After a number of choose-it-yourself projects I am having a GC redo my master bath. She is adamantly anti-Lowes on plumbing due to "poor quality" and "accepting B level products" (eg slightly defective but still working). "Shopping" with her at a plumbing supply house was quite an experience because there were no prices on anything. For me any purchase is a balance of decisions between price and features and anticipated lifetime of use. I didn't like it. Also, choices were limited compared to Lowes.
My question is...how do you feel the higher-end Lowes stuff stacks up against moderate-end plumbing supply house? Is it really -that much- worse? Or is this just a "GC shuffle" whereby they keep their frequent suppliers happy, and the homeowner pays a 20% premium for one copper part (lifetime 40 years) as opposed to one plastic part (lifetime 20 years)?
