A few years ago I had the septic emptied. A few months after that I had all new leach lines installed which included doubling the length. Had no problems until this year when I got a backup. My laundry room has an exit point for backups (poor poor house design) so when ever there's a clog, everything in the house backs up into my laundry room. I opened the clean-out at the end of the porch, nothing in particular came out. Plumber came out and snaked it. Again nothing spectacular other then a small amount of kitchen grease so my wife and were extra careful making sure no kitchen grease went down the sink. Starting last night, backing up again. I am at a complete loss as to what the heck is happening. I'm waiting for a plumber to call back, hopefully they can come today and this time I've requested a video camera to see if there is a collapsed pipe or a crack under the house. Does anybody have any other ideas or suggestions as to what's going on? I'm so frustrated. Thanks.
