|In response to Re: washer drain effect on downstream toilets|
That would usually indicate a partially plugged sewer system, and since the washer is forcing water into the system, the studor vent is preventing the air from being expelled so it comes up in the toilets and the pressure which is developed prevents the toilets from draining.
: I have two upstairs toilets which are downstream from the upstair washing machine. When the washing machine drains, the water in the toilets moves up and down (sometimes a bubble comes up) and you cannot flush the toilets when the washing machine drains. I'm guessing it's siphonage from the force of the draining water. Is there anything I can do to prevent or minimize the siphonage? There is a 2 inch vent that terminates in the attic with a Studor AAV minivent - would changing to a bigger AAV help add venting or am I limited by the vent pipe size?
