  • Laundry Vent

    Hi All.

    I'm new to this forum. I just moved in to this house. I thought that the laundry vent looked strange. I was hoping someone could tell me if this laundry drain was vented properly, or do I need to call someone.
    I've attached a pic.(I think) The pipe in the foreground is 1.5" to a sanitary tee. going into a 2" drain. I hope I explained this right.
    Thanks in advance.

                  Heya Jack from a fella Bostonian ...it's fine.
                  The 2" drain is in fact very good, our code only requires 1-1/2" for a laundry.

                  The distance from trap to vent has to be 2 times the diameter plus 2 converted from inches to feet.

                  In other words, 2 times 2" plus 2 equals 6'.

                  That vent is well within 6'...the ONLY thing I could pick at is the Tee-wye on it's back..it really should have been a wye + eighth bend (combo wye).

                  Most inspectors wouldn't really pick at that though.

                  Good luck with the new home...you picked an EXCELLENT time to buy in Boston.

                        I think you meant standpipe, no more thaN 28" on a laundry here.
                        24" on everything else.

                              The question was not directed at you at all. Just the OP.

                              Here the IPC interpretation is:

                              Laundry box 35" above the finished floor.

                              Minimum 24" drop to trap weir. Maximum 48".

                              No san. T's on their back or horizontal drainage period.

                              NO DRILLING HORIZONTAL OVER 1.5" PIPE. Regardless of live/dead load or double studding. Pretty much kills your trap on the topside. Don't go moving studs too much either.

                              I forget the distance required from a san. tee vent to the trap outlet. 2 times something another. Basically 6" or more.

                              No trap on exterior wall without 6" wall/insulation.

                              Vent within 6'. Drain branch must be increased to 3" within 6' or less.

                              Need primer.

                              I still want to see all of this ran through clear pipe with all the measurements out of range to see if the trap siphons.

                              J.C.
