Bottle trap

Found this in Lowes. So are they legal now? Package did not have CSA or UL logo.
BTW check out the Lowes icon for the plumbing section it could explain a lot,


There is no law against selling unapproved products, but there is for a licensed tradesperson to install an unapproved product.

That’s not 100% true Mr. Jonas, there are plenty of unapproved products that are illegal to sell.

Not allowed in Wisconsin but ok if approved by the plumbing inspector in Minnesota I guess as I have seen them on commercial sinks.

I would not write it as a defect, maybe a concern at most.
