I am installing a washer in a new location and PVC drain. It is fairly close to the 2" copper drain line for the bathroom and kitchen sinks. Will the 2" line be able to handle the bathroom and kitchen sinks and the washer? If so, would a Fernco Tee be the easiest way to connect to the copper drain? Any tips on ensuring a good trouble free drainage of the washer and what the min vent should be for the fixtures?
