I'm having an issue with suds in my toilet when I run the washer (when the washer drains). I have two bathrooms, and it's only happening in the master bath. It's also gurgling beforehand. Any help is appreciated, I hate to spend hundreds of dollars on a plumber if I don't have to.

Thanks,
Christina

Your vent stack is partially blocked and/or your drain line. One or both issues are causing your drain line to be over filled and backs up into the toilet. I am just surprised its going to the toilet and not your master shower or tub which are about 12" closer to the problem.
