Overflowing & burping tub/toilets already snaked.
My middle bathroom toilet was burping when we used the shower in there and water would come up out of the tub in our master bath. The shower was draining slowly. We read that it might be the vents on the roof so we attempted to flush those out with a yard hose (water just came up in the showers). We rented a 75' auger and fed it through "clean out" in the back yard, the toilets in both bathrooms (now the toilet in the main bath is leaking... back to Lowe's for yet another wax ring hoping that will fix that issue) and the shower in both bathrooms. Returned the rented auger this morning even though we are still having the same problem. We are on a septic tank but it was just emptied about a year ago and we have only lived here about 9 months so we hope it is not that. The kitchen drain does not seem to be affected. Anyone have any ideas? PLEASE. I am pretty handy in the electrical field but am lacking with plumbing.
