Hi All,
First time poster.

I replaced a vanity cabinet with an open style vanity.
The stubout is now too low and the ptrap needs to be raised up to fit.
There is plenty of drop, in fact I had to add 6 inches to compensate for the new sink which sits much higher (shallow bowl and taller vanity)
My question is, can I install 2-90 degree elbows (or 45's)at the stubout to raise the height of the horizontal drain pipe.
Not sure if this drawing will come through.
Thanks

If you raise the stub out you will be creating a S trap which is not allowed in any code and would subject the trap to siphon allowing sewer gas into the home. The better solution would be to add a extension tube to the sink tail piece before the trap.
