Vent Kit Original


really really off the wall question about plumbing,,i need the true pro's here,,,, drain backing up?

house about 60 years old,,original pipes go from kit sink,,dw,,to bath then out east to yard,,angle to corner of lot

15 years back ,,addition to house ,,utility room,,bath,,out north to yard,,to corner of lot,,
lines tie here and to city sewer,,which I am told is a 3 " pvc inside a 4" tile (is this possible)

when dw and washing machine both running,,water backs up in original tub,,but not in added tub,,(both on same level)
have been told this was a vent issue
any other ideas??

here is where the pro comes in----can i talk into the bath overflow and hear it on the roof if I can get water out of trap??

hey its Saturday and what else do you have to do huh,,,taxes

It is possible that it is a 3" PVC to 4" tile to sewer. My problem is did they tie into the 4" drain tile at the top or side of pipe, in other words a T connection of some sort. If they did it is possible the pipe moved into the 4" tile to far and is restricting the flow backing up into the old existing drain for the old bathtub.
Than slowly drains out. If it were a vent problem your toilet after flushing and refills, the water would bounce up and down showing that a suction is effecting it as it drains. If there is no bouncing of the water in toilet than the vent is ok and you have a blockage.
