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.

Although a check valve will prevent sewage from backing up into your washer. You also need a trap to prevent sewer gas from coming back up into the washer and contaminating the clothing with smells. This whole job needs to be done to code. A proper tee needs to be cut into the riser, with the right connectors. A vent needs to be installed and reconnected back to the vent stack. Then you need to have a riser installed above the trap that is called the standpipe. Get a book on home plumbing at one of the home warehouse stores.

Good Luck
