Yes, over a year. A little over a year ago I had the toilet back up. Used a plunger and a few quick plunges and it was all cleared. A few days later the same thing. I used a toilet auger and nothing happened. Used a plunger and a few plunges and it was all clear. A week or 2 went by and the same thing happened. In a 2 month period this happened about 5 -6 times. Went and bought a new toilet to get rid of the problem. Put in in and a few weeks later the same thing. In the last year this has happened about 25 times. The toilet is located on the ground level. No basement and it is near the stack pipe I think it's called. We checked the roofpipe and the inside of the pipe for a birds nest and there is none. In the last week it has happened 3 times. I believe the downstairs shower and the toilet are hooked together as sometimes you can hear a gurgling in the shower when the toilet is going to clog. We have lived here for 25 years. 24 years and no problem. This is driving me crazy. Anyone got any ideas? I have poured draino, etc down the shower in hopes that maybe there was a clog.
