Has anyone here used a pipe snake? Do they work well? Are they good for non-plumbers/is the learning curve small? How well do they handle forked pipes? We're having problems. Plungering doesn't work because we have some pipe joint issues, and a plunger with appreciable force will break the joints. A pipe snake, even at it's not-poor-friendly price would be cheaper. I'm wanting to go to Home Depot and by my mom one for mother's day today, but I was hoping for some quick opinions/reports first. TIA.
