Not sure if this is the right spot for this post so if it needs to be moved thats ok. The floor in my basement is slanted where we have our washer. Its so bad I have a 2x4 under one side. This will hold for a few washes but it keeps sliding down hill over time. Yes I know just move the washer to another location but this is the most convenient for the water hook up and drain. Any suggestions to keep the washer in place?
