In response to Re: washing machine drainage pipe size
A 2" pipe is pretty standard and it will actually handle almost twice the amount of water as the 1-1/2". (Area of a circle = Pi x radius squared, so a 1-1/2 has about 1-3/4 sq in. area and a 2" has over 3 sq in.) There should be a pee trap before the water enters the main drain. My Maytag washer drains into a 2" drain pipe, the pee trap is about 3 feet below the top of the pipe and the pee trap is connected to the drain. I have no problems with draining.
