Hi,

Name:  Island Loop Vent.jpg
Views: 3524
Size:  29.0 KBAs part of a kitchen remodel, we are moving our island sink. The loop vent needs to be modified, but it looks like the current installation is not done correctly, and we may have an inspection issue if we keep it. The pipe to the exterior vent is connected to the drain side of the loop instead of the vent side, and the clean out is also on the drain side. I have created a simple diagram showing what I mean.

What do you think - Will a loop vent work correctly in this configuration? Would it pass a typical inspection?

Thanks!
