Dear all,

I have 2 vanity sinks that drain into one drain in the center. The connected drain in the center is vented properly and is as per code. What is the best and correct way to connect the 2 sinks to the drain.

The inspector said that the current configuration is causing an S trap instead of U and is not allowed by code.

What are my remediation options? Should we put a T instead of elbow and connect to the air vent from above?

He's looking for a double fixture fitting with the trap arms going straight out from it, graded at 1/4" per foot, no more that 42" long.

What you had before will siphon the p-traps. Your bathroom will smell so much better after the fix.
