Curious on why to use a baffle tee rather than a combo wye to connect the outlet flow? Builder used to baffle tee and we have had issues over the 10 yrs here. I put in a new disposal so now the time for a change if a flow advantage is there. Now the drain outside is turned 20 or so degrees towards the left hand sink, and the disposal is on the right sink (shallower). My thought is to put the P Trap on the left where it is out to the drain, and rather than a baffle tee, put in a combo wye which the disposal will connect. The DW is also into the disposal. The AAV is done correct for an island so no issues there. Would not the combo wye handle the water out better than the constriction inherent in a baffle tee? And my thought also is to use the disposal provided tail, then down to two 45 degree hard PVC fittings (long 90 degree), straight across to the wye. Thanks to anyone with a little insight. Either solution is code here in AL.
