Water Pipes keep clogging up
My water pipes keep clogging! The pipe from my house to the street sewer pipe keeps blocking. We've had it snaked, cleared and camera-ed and it continues to block. For instance, everything was fine for about a week, then tonight I ran the washing machine upstairs. When it drained, I heard the familiar bubbling sound in the downstairs toilet, went outside and sure enough the cleanout drain was gushing water. It is full as I write this bc I can't get it cleared out until daylight. All the pipes are good--camera proves it. The pipe that connects to the city is ROUND-not collapsed. The neighbors are not having trouble, My plumber thinks there is a block in the city's line but the city line is running ok too. I have 3 big guys (ahem), a couple of regular 1.6 gallon toilets (that aren't very good) and one pressure-assisted toilet downstairs. IDEAS?
