toilet bubbling
Posted by Pat and Fred on November 10, 2001 at 12:14:25:
We have a 3 year old septic system. The the water softener drain connects to it. When the softener cycles, the toilet begins to bubble loudly and splashes water out. This continues for several hours. There is no bad odor when this happens. While this is going on we can flush the toilets but they fill to the rim and very slowly drain completely and then bubble. What is causing this and how is it fixed?
