I had my main line augered 2 months ago and now I am backing up again.There is overflow at the cleanout particularly laundry cycles and tub.But what baffles me is this,when I place a toilet plunger over the cleanout and pump it vigourously a few times or little while the water drains on forward.If it was a major blockage I shouldn't be able to get the water to pass? Does this sounds like a mild blockage or slight root infestation? Sometimes everything drains fine to a point it backs up again especially with a large volume of water.Does this sound like a pipe collapse surely not if a plunger forces the water on through.Any suggestions be appreciated.

My guess would be roots at the street raiser but to be sure have a plumber run a Sewer Cam through to the street. Let me know what he finds, Good luck, Tom

Tom you nailed it on the head.Roots were found at that connection and also waste/tissue was accumulating there affecting drainage.I asked for assistance they will,time to get out the checkbook oh boy.

You do have options here.
1- Dig up the raiser, remove the roots and recaulk the connection. **OR**
2- Keep the checkbook in your pocket and If you wish to control root problem RootX or Robics Foaming Root Killer that contain Dichlobrnic are two products you could try.
A less expensive way would be to call around to garden supply stores and ask for fine grain Copper Sulphate. Put a 1/2 pound in your toilet and flush it down. Repeat in 6 months.
Hope this helps and thank you for rating my answer, Tom
