Hi, We just bought a house and the former owners had no issues with their washer draing, so here goes. We have a commercial grade Speed Queen washer and when we put in a large load and it spins, the drain pipe as well as the sink where the drain for the washer is also connected overflows from the sink as well as the drain pipe where the washer is connected as well as the kichen sink that is approx. a good fifty feet away. Can anyone help? Thanking you in advance for your immediate atttention in this very critical matter.
