In response to Re: Sanitary Tee vs. Vent Tee
: Where a vent takes off vertically from a horizontal drain, or where a horizontal and vertical vent are tied together above the highest fixture, does it matter whether a vent tee or a sanitary tee is used? And if it doesn't, why do they make vent tees?

Where a vent is taken off a horizontal drainage line, you must use a wye or a combination fitting. You cannot use a san tee. You use a san tee when you are taking a vent off a vertical pipe or tying vents together. You use a vent tee where you tie vents together. I use san tees rather than vent tees.
