The vent stops the siphoning. distance to well is a concern and then the size of septic tank and field if it was big enough to handle laundry.
Yeah. I think the well is about 20 feet away from the house and is on the side with the laundry. Septic tank is on the opposite side. Just had a new septic tank put in a few years back with larger capacity and got new drainfield set up.
I'll have to search through the files I transferred from my father's old hard drive to see if I can find any documents that mark waterline locations. I might need to get the right software to view it. He had CAD and some other stuff on his computer.
I made a rough sketch that shows the yard and spots where I know there are/were water faucets. Blue represents water. Orange is utility poles.
Only four water spots are still working--
1. The one just outside the back door
2. The one to the water trough just outside the fence to the right of the house
3. The utility sink inside the workshop
4. The faucet on the fence that is at the southeast corner of the house
The rest had to be capped off-- the one near the utility pole after the field lines was capped at the field lines. The one to the north of the house (left side) on the fence is capped off slightly south of that because of the arborists.
Just south of the fence below the house we used to have underground hose to water the blueberry patch, but the blueberries are long dead.
