I just bought an older home, it came with a washing machine in the basement. My problem is as follows, waste water flows back into the washing machine. I get city water and sewage. There is a waste line with a 1 1/4 inch galvanized pipe drilled into it. I noticed that the washing machine discharge hose slides right into the galvanized pipe. There was also a cap sitting nearby, to cap the pipe when the washer wasnt being used.
So I assume i have to put in some sorta check vavle to stop water from flowing back into the washer. But do i need to do something else ? Thanks In advance for any help.
