Blocked vent?

Sometimes when the washing machine is draining, the toilet starts "glub, glubbing". I have also heard noise from the washer drainage pipe when the toilet is flushed. Is a blocked vent also causing this or is it something else?

Re: Blocked vent?

It sounds like a main line stoppage. Vents if piped properly get plugged very seldom. The main line may not be totally plugged, but in either case the line should be snaked.
