Product review (5 stars): I've lived in my house for over 20 years and ...
I've lived in my house for over 20 years and never used a lint trap on my washing machine drain hose. Even though every plumber has suggested I get a lint trap. Then, my utility tub drain backed up under the basement floor. I tried the usual remedies, all but calling a pro. Eventually, I angered my wife because she had to wash dishes in the kitchen right above the laundry tub very slowly, so the water didn't back up over the lower level tub.

In comes the professional plumber, and the Number One thing he pulled out of my floor drain causing the clog? Lint from the washing machine. After every load of laundry, I'm stunned by how much lint these things grab which means this is particulate that is NOT going down my floor drain. The plumber charged my $150.00, these little lint traps cost way, way less. I just won't ever, ever go without one again.
