    Toilet/lav/tub drain
    My toilet currently drains into a 90 degree 3" x 3" bend with a 2" side inlet. The bathtub & lavatory both join just upstream and outfall into the 2" side inlet.

    I am shifting my toilet over a foot and was wondering if it would be a better idea to outfall the 2" tub/lav drain into a fitting just downstream of the closet bend or does it really matter that it outfalls directly into the bend? It seems to work OK under the current configuration but since I was going to be modifying the outfall somewhat anyway...

    Thanks

    It would be better if the 2" is connected upstream so the toilet does not flow past it.

    I thought the same . The only practical way I see to accomplish that would be to replace the existing closetbend/side inlet with a 90 degree bend with an "in-line" end inlet. The lav/tub drain would still go directly through the toilet drain bend. Actually, that might work a bit better from an install standpoint even if the performance is unchanged.

    Thanks
