I sent this to the builder.
Who was the plumber? I had the septic backup yesterday and my septic guy came out today to resolve the issue. It turned out to be the water test pig was left somewhere in the lines. I just want to make sure I know who he is. Thanks. Power outside on the garage is also connected.
Stay dry and stay warm.

With the rain outside and the septic in the fritz we agreed not to lay the shower pebble floor.

What a wonderful day. The toilet appears to be backing up, but it turns out it is something wwith te septic system. I opened up the cleanout tube and water came out. I opened up the grey water line and water came out. I am unable to turn off the grey to black as the box shifted and I cannot turn off the connecting valve. If I could shut off the switch I may be able to better to identify the issue.

I called the septic installer for help. He said he will be out Monday afternoon or Tuesday.
