My toilet seems to bubble when ever the shower is being used. We thought is was because of the washing maching, but we took it off the septic. We had the septic drained about 4 weeks ago. The toilet does not back up, just bubbles. Could it be the drain line? (it is only six years old.) Could it be from dirt and sand in the septic? Could it be the toilet? (the toilet I believe is the orginal to the house and the house was built in the late 1950’s) Please help!!!!!!
