I have been giving them a lot of thought lately, starting with Cloacina (scroll down to Poster 6).
The line to the septic tank at the guest cabin was clogged beyond my ability to clear it with a hand-cranked snake, so I had to call Cory the plumber.
And since the tank itself had not been pumped for a decade, I called the septic service to pump it. When the pump truck showed up, we discovered the baffle on the outlet pipe had fallen off. I got new parts from the hardware store (a four-inch 90-degree PVC elbow and a neoprene coupling to attach it to four-inch clay pipe, if you're wondering) to replace it.
It's a small tank, so I was able to attach the baffle by just hanging over the opening and reaching down. Didn't drop the screwdriver--hurray. The tank was empty, but still pungent.
I figure that M. could have fit through the opening and climbed down on a ladder, but for some reason she was not interested in helping.
So all honor to Cloacina, a goddess below.
