My bathtub drains okay until almost finished. It stops draining for a few seconds and the toilet begins bubbling. The tub then finishes draining and the water bounces around the pipes (very loud rushing water) until it finally gurgles out the main exit pipe. Our septic was pumped less than a month ago. No problems with any other drains in the house. No septic smells. Could this be a partial blockage or venting issue?
