I have the concrete stationary tubs, one big tub with a petition in the middle making two tubs. In the back right and left hand corners of the two tubs are the drains. These drains immediately go in one inch and one half pipe with a trap. The wash machine pumps the waste into the left tub. As it drains into the main drain, some of the waste to about a depth on one to two inches comes up into the right tub. However, if I fill up the right tub with water, it will drain without any of the drain water coming up into the left tub. And no, I don't want to drain the wash machine into the right tub. What's going on?
