combo wyes aren't the same as fixture cross fittings like the one you have installed. just break up a little more concrete on either end of the 4" pipe, use a small section of 4" pvc to connect two 4x2 wyes together and install them
It's not a cross fitting that I have installed, it's a double-wye fitting, which appears to be consistent with chapter 7 of the code as I pasted above. Why is this not correct?
