Kyle showed up this morning with the drain camera. The camera is on the tip of a long cable and communicates with a specialized iPad in a case.
The camera and cable go down into the clean out pipe and transmit video back to the computer which displays and records it.
Most of the video is uninteresting -- just a long sequence of a white pipe.
But you can see, in the upper left corner, a time-stamp. And in the lower left corner, in white, in brackets, how far down the pipe we are.
As I said, mostly it's uninteresting, but occasionally, you hit a joint
Or here, at 9 feet in, we have gone under the gate into the back yard and are turning to go over and run along the fence.
At 18 feet, we are along the fence and turn to run parallel to it.
Further down, we run into some twigs that got into the drain and have not yet been flushed down or decomposed. We actually ran into some at 26 and 34, but the camera will actually push them down the pipe as it moves forward.
At 53 feet, we hit another turn, where the side fence stops at the fence along the back of the lot (on the West side) and turns to continue down the back yard.
Then, at 59 feet, the bottom of the pipe seems to fall off. Kyle says this looks like the pipe has been broken or collapsed.
And a few feet more, a massive root ball. Kyle says this is most likely from the big old oak tree in the back.
Then, to know exactly where the camera is, Kyle could turn the cable into an antenna of some kind generating a signal that he could pick up with a locator device to follow the cable from the clean out pipe down the back yard to exactly where this root ball is, and he marked it on the ground with a big white circle ( and I stuck a yellow flag).
So we know exactly where the problem is. I can dig down and find the French drain at this location, take it apart, repair it and we will be back in business. Also this would be a good spot for another clean-out pipe. Apparently, good practice is a clean-out pipe every 50 feet.
