: : : : i've read here that a sanitary tee can only be used in a vertical position. I have 5' extentions to two fixtures (a wet bar sink and a lav), the lav is in the center and i have laid a sanitary tee horizontal to stub out this center fixture. is there some other fitting i should use?

: : : The correct fitting to use on a horizontal drain line would be a wye with a street 45 to make the stub out square. A regular ty or sanitary tee would prevent proper flow.
: : : ...What are you doing about venting?
: : : Good Luck. e-plumber

: : I've consulted a local plumber and called the building inspector and they have approved my plans. This is a three-year old house, with the basement stubbed out for a bathroom. I am installing that bathroom now. there is a 4" stub riser for the toilet and a hole with 2" stub out for the shower. just behind the toilet stub out is a 2" (vent) line that runs up through the roof. (the main soil stack for the upper two stories of the home is "up" the line from all of this stuff). I am tapping that 2" line, teeing off with a san tee and extending 5' a 2" extension to the drains on the wet bar sink and lav. It would be nice to know what the venting is called---wet? I was told I did not need to loop vent the two fixtures because I am only going 5'.

: : please advise if this sounds right to you all.

: Who told you you didn't need to vent? These sinks need to be vented. The distance is really immaterial. You are creating s-traps by running this way. I will repeat, You CANNOT use a san tee on the horizontal.

the sinks are vented, trought a 2" through the roof. the 5' is the maximum distance allowed between a p-trap and the vent, using 2" PVC. the san-tee in use will not be horizontal, it will be vertical. i was going to use another san-tee in the horizontal position to plug in the intermdiate lavatory to the 5' 2" horizonatal connecting line. now, however, i will use a wye and a street 45. the end of the 5' linkage will attach to the wet bar p-trap through a long 90. none of these fitting used in a horizontal position point down, no s-trap is created, it is all on the horizonatal, with p-traps plugging into the line, which connects to the drain/vent.

maybe we just aren't on the same page.
