Toilet bubbling after clearing stubborn bathtub drain!
OK so we had a bathtub that was draining very slow for a long time now. So we tried using some drain cleaning gel and it did nothing to it. Soo I have read about using a plunger, so after I rinsed the drain well with a lot of water, I took a plunger to the drain and Voilą! It worked perfectly. So I was happy that the tub drain worked, I scrubbed and cleaned the tub which had gotten dirty due to the slow draining. So then I start turning the water on and rinsing all the dirt down the drain and its working fine, then I hear a bubbling sound. I turn around and I see bubbles coming UP from inside the toilet!!
So I turn off the bathtub water, go to wash my hands and when I wash my hands the toilet bubbles again! Basically, every time I turn on the bathtub water or sink water I hear the toilet bubbling. What is causing this and how can I fix this! This has never happened before. Thanks a lot.
