What is clogging your drain(s)? Is there something (cheaper) that you could do to prevent clogs?

nothing generally but the new sink requires new plumbing (old was to corroded/leaking),,,

Others may differ, but I wouldn't go that route.

At my house, care is taken to not put things in the drain that will cause problems. This trap purports to solve a problem that should not exist.
Evidently it is about to be discontinued as the original price was about $30.00 and Amazon is offering it for about $10.00.
