I was taking a shower today and the washing machine was going. I heard the washing machine drain when I started hearing bubbles coming from the toilet. The shower drain started bubbling and stuff came up the drain and it won't go back down. The toilets filed with nasty looking water and it won't plunge down just like the tubs. This happened in both bathrooms. Now water is flowing from the toilets fludding the bathrooms!

Main drain clog... or worse... YIKES! Did the city/town sewer department come by and flood your place... or did the water stop flowing when you stopped using it..?

Answer those questions and will see how to best advise. Good luck!
