....you know the rest. Had a drain blockage in my (slab foundation) home. 2nd bath and kitchen both backing up. Removed toilet and ran a flat iron pipe snake down until it stopped. Worked it back and forth with no luck. Couldn't clear the blockage. Called in a pro. He ran an electric auger down. When he brought it back out, there was a little mud on it...which is not good. Recommended running a camera down just to be sure...I agreed. Sure enough, camera shows the pipe wall is busted in a tee fitting right under the wall between my master bath shower wall and laundry room. So....shower has to be removed (likely will have to cut it up to remove it), tile pulled up, concrete cut/busted out and likely a portion of drywall to access and replace the tee fitting. Then of course patching it all back up and a whole new shower installed. The company I used is going to give me an estimate...of course I will get a few more. Off to an expensive new year.
