There seems to be a lot of questions regarding
my 3" pipe.. I am the OP here. Some said to measure
with a ruler..I went a step further by circling it
with a string, than lied it down a ruler and it
measured 6". So half of that, I believe would be
the diameter...so do the math. It was circled around
the red tape area cause that is where it was inserted
into the T-pipe. Regardless, a genuine plumber is
coming today to take all out and replaced with the
latest P trap and etc, minus the T-pipe. Thanks to
all...except the troll caller. LOL


Uhm, that's the wrong divisor. You need pi, not half.
