Need some help with a back filling sink !!!!

[Smangle]

heya

we have just moved into a 3 story town house where the drainage runs through a pipe down the inside the house the problem is that when i pull the plug after washing up the water flows into my washing machine and when i drain the washing machine it just fills the sink and the drains away realy slowy (probly back into the machine ) i have niticed that the waste pipe runing from the sink i bowed in 2 places each about an inch higher than the washing machine drain conection on the bottom of the sink i got hold of the previous owner of the house and she has said that it has always done it. So my question is would it be the bowed waste pipe that is causing this any help would be spectacular because the local H/A seems to think that it is somthing to do with my washing machine but hot point man said its the waste pipe.

cheers.

sounds like a partial blockage, you could try using a plunger on your sink but would have to blank off the drainage connection from washing machine and sink overflow(assuming its a combined sink/washing machine trap)

sounds like drainage problem to me

hello Smangle,
difficult to call without seeing the problem, but yes the pipes need to have a continual fall to flow properly, possibly waste pipe is partially blocked as well. new waste pipe is not expensive, likely easiest to renew the section of pipe and add sufficient clips.
