Clogged Drain Pipe

I manage a four family building. Two apartments on the first floor, 2 on the second. Today, the second floor rear tenant called about a backed up kitchen sink that was also backing up into the bathroom sink. The bathroom and kitchen share a wall.

I call a local drain cleaner. He manages to clear the line using a snake and air pressure. As he opened the faucet to test the draining for several minutes, the downstairs tenant calls me frantically that his bathroom sink and tub were overflowing with sewage.

Seems like the clog from the 2nd floor was pushed down to the first floor.

The drain guy snakes the bath tub and the bathroom sink and nothing is moving. We go to the basement. The front trap/cleanout was flowing normally. The back trap showed no signs of backup.

Now it's a mystery....where is this clog and what is this clog? This is not the first drain clog in building as we have had many. However, in the past, the line was cleared easilty and everything flowed normally.

Who do I call now...another drain cleaner? a plumber?

Help!!! The two back tenants cannot use their bathroom sinks/tubs and one cannot use the kitchen sink. And of course, it's Saturday night of a three-day weekend.

BTW this is a 103 year old building in Brooklyn, NY

    What you have is likely close to 103 years of kitchen sink grease, hair, muck, mop strings and splooge that has built up like a clogged artery over the years and you need angio-plasty!  Dislodged clogs CAN migrate.  A good sewer cleaning pro can use of their many snakes and tricks to get the clog...usually without cutting in ti the pipes.  If that don't work you meant need a real plumber to cut out the bad section and snake it again. If they do try to have them leave a clean out wye or tee for easy future access. Good luck. Mad Dog 🐕

    A camera snake is invaluable in a situation like this.

    One solution would be to push a water jet rodder through the vent stack on the roof to clear the clog.

    They should run the camera down through the vent stack on the roof to find the blockage and they can use a high pressure water jet nozzle or the correct size drain blockage cutter with the heavy steel coil sections.

    I have found the drain flusher from peterson products work very well to clear clogs.

    All you need to do is hook it up to a garden hose attached to a hot water faucet and insert the bag as far as it will go and turn the hot water on and wait and it will force and flush the clogs out.

    www.petersonproducts.com/Drain-Flusher.

    Go to the local lowes or a plumbing supply place and you should be able to buy a peterson drain flusher with the canvas bag body.

    If you do not have a garden hose adapter for a standard sink faucet you will need one unless you have a hot water faucet in a nearby laundry or slop sink with a boiler drain connection thread.

    I second the need to run a camera down the line, all the way to the street, actually.
    Kitchen drains may need a jetter, as the grease sludge can just get pushed down the line with just a cable
