Odd trap / drain depth question.

[Terry]

Just so you know, I turned down a job this Summer where I would have had to crawl under a patio slab to work on the connection of the house sewer to the septic tank. The ground had settled and the connection had broken and was leaking water and sewage there. I let someone else crawl in there on their belly and did the top out.

I cannot understand why a septic tank would have to be moved 100' if the existing one is under the house.

Nah, I'd still be grumpy. I was born grumpy

I cannot understand why a septic tank would have to be moved 100' if the existing one is under the house.

If it has to be 25' from the house, there is no place to move it and still have room for the field.

Exit the back door, take two strides, and you are standing on the tank. Take six more strides and you will fall straight down about 10'. It isn't straight down after that, but it is very steep.

Standing at the back door, to the right of the tank is a postage stamp sized yard that I believe is the lateral field. To the left is hillside. (The house is set into the hill on two sides.)

If you go up the slope far enough, we have a good sized pasture on the ridge top. We also have a couple of pastures in the opposite direction, but the pipe would have to cross a deep ravine.

It is a beautiful place. Lots of deer, turkeys, foxes, raccoons, and way too many coyotes.
