Yesterday the shower drain and the garage drain backed up at the same time. 15 minutes later both drains started draining again. This morning the garage drain backed up again and at same time the toilet nearest the drain was gurgling. Once again, 10-15minutes later it drained. Shower drain did not back up this time but toilet in bathroom didn't flush all the way(different toilet). All are built on a slab. What is going on? Please help.

City sewer or septic tank? You have a partial blockage downstream from the lowest point in the system. Which is the fixture nearest to where the sewer line either runs to the street or to the septic tank> Or is it the garage? I need more information before I can offer a solution. Back to you, Tom

City sewer

At this point you must locate the clog. Lovate and open up the house clean out. Give the toilet a few flushes and watch the water level in the pipe . If it builds up then snake to the street. If it backs up in the house pull the toilet that gurgles and snake from there, Good luck, Tom
