    Hello
    Has anyone seen this issue?
    It all started when we saw a puddle of water on the floor in the basement in the half bath / laundry and room. After checking all the water pipes and washing machine with no sign of a leak!
    Finally I noticed in this laundry room that turning the sink water on and flushing the toilet 3 times caused the backup and very large bubbles in the toilet! The water came out of the bottom of the toilet on the floor. Probably from the toilet Flange in the floor under the toilet. So after a while the water would eventually drain and the toilet could be flushed once or twice at the most with large bubbles.
    So I put a 25 foot snake into the cleanout that goes into the pipe into the front yard. I felt something at approx 10 feet and a pulled out a small amount of organic matter. No fix.
    Next I put a hose down and got pass the 10 foot problem area and turned on the 100 psi water full blast and it drained fine. Then I pulled the hose back less than 10 feet and again turned the water on full blast. Sure enough the pipe filled up and backed up on the floor! So the problem is at 10 feet or 8 feet from the front of the house approx 2 feet down. Got the shovel out and started digging. No water on the ground but this is close to where the new PVC line from the street sewer pipe connects to the old cast iron drain pipe into the foundation just below the concrete floor.
    After digging the connection looks good no sagging or collapse. See pic
    Now today after 5 days of this traumatic event the problem is gone! During a shower we ran the sink and flushed both toilets a total of 5 times and no bibles in the basement toilet and no backup!
    Before the water leak we did have a strange smell and put baking soda and liquid plumber down the drain with no fix!
    Therefore now that it is working?
    I checked with the neighbors and they did not have a problem?
    Could a piece of iron inside the pipe flak off and clog it up?
    Or
    Due to the record high rainfall this spring could something have floated back into the pipe from the high water table to clog it too?
    Did the baking soda help or has the water table in the ground drop?
    Any comments?

    Pic 2 - PVC cleanout that is in between pvc pipe to toilet and pvc pipe that connects to old iron pipe going to street. New PVC stack in back right corner that goes straight up to roof and second floor bathroom connects into it.

    Had sort of the same problem a few years ago at my Fathers home
    The only difference is it was roots growing into the clay pipe . Used a
    cutter to clean the pipe to the street . The house was sold 2 years ago
    last fall got a call from the new owner . It had happened again only this
    time they dug it up Eight feet down . The new owner wanted me to pay for it
    i said NO they then sent me a lawyers letter threatening to Sue . My Lawyer
    said go ahead and when you lose you will also pay costs Last I heard of it
    You may have knocked something loose that plunged the pipe again until it
    flushed itself away

    my first thought was that some roots have grown into the pipe... I have seen pvc crack just enough to let something take root down in the pipe and plug it. Your situation sounds very peculiar.

    Hello
    I just found out something! My neighbor who lives behind me had the same problem and spent thousands and they found in the pipe 3 feet from the front of the house by the stairs Which routes in the place as my house a stuck flapper valve that broke off the hinge in the metal sewer pipe!!! This happened in Feb 2014 to my neighbor and he saved the flapper and I took a pic of it! They had to put a camera in the pipe to locate this flapper and cut out that section of pipe to fix it for $1500.00!!

    The camera scoping is $275 around here but if I do it myself it cost $27.99 using my laptop from Amazon!
    See
    https://www.amazon.com/dp/B01N19YCC3/?tag=hearthamazon-20

    The valve was put in as a backflow preventer back in 1962!

    Is it just the pic or does the cast from your house go up hill into the city connection?
    I just had similar problem and it was organics, fats, etc that had built up in the pipe over years. Took me hours to get it freed up i finally got a small hole through the plug and just kept working at it and dumping boiling water down the line.. Probably running your hose down started to clear the blockage and the rest got pushed out during normal usage.. Putting baking soda down a drain is bad.. It will plug things up and if that ever dries up it will be like concrete im actually betting that was part of your issue..
    Leave that camera on amazon they are not worth it. The cable is so light that you will be lucky to shove it 5ft down your line and never the 50ft trust me i have one.
    Spend the money on the plumber and get a good picture of whats going on. If its organics plugging up the pipe its not going to cost you much more to have him auger it out while he is their compared to calling him in

    FYI, backflow preventers on sewer lines are a very critical component that is forgotten about until they are needed. In an older city, sewer lines can be undersized and during flooding events, if the backflow preventer is not in place, the sewerage will back up into the house. Many insurance companies specifically exclude sewer backups from coverage without a rider. Definitely think about it before removing them unless you plan to be selling your house soon.

    I just found out that running a snake is $549 if they have to go in through the toilet Flange by removing the toilet or $429 if there is a cleanout handy. Well I have an easy to undo clean-out in the floor and the 25 foot Lowe’s $18.48 snake that I can attach to my drill works just fine!

    The local profession roto rooter man’s camera TV view cost $379.00 so I will try the $27.00 lap top camera since as of Sunday everything is draining fine!

    That snake is going to do nothing... you need something with a cutting head on it to clean the pipes out.. Try your local rental place for a better quality and pray that since you are DIYing it that you dont brake the old cast pipe.. If you do that plumbers bill is going to look small in comparison.. As for teh camera theri is a reason that the professional camara cable is about a inch in diameter and stiff and the ebay camera cable is 1/4 inch if your lucky and flexible... trust me i have one and have tried it.
    What was the brake down of the quote from plumber? our locals only charge a hourly rate and i could have it done for a min one hour charge here. I had 200ft of pipe scoped for less than what they are quoting you
