The numbers next to the small round steel cover (which is a cover over a steel pipe which leads down to, and maintains access to, a shut off valve in a water line) are telling you it's a 6" diameter vertical pipe under the cover, and it is 2' 7" down to the top of the valve.

Anyways, I know you can use the split pump but I’m interested to see if any landlords or home owners have installed a small diameter HVAC unit into their units?

Ok, so I have this rather large tree (4-5' diameter) in front of my SFH property.  

There was one time that I was in the top of a tobacco barn, standing on poles no more than 4-inches in diameter which were about 4 feet apart - and probably 30 feet off the ground.

But the function is limited by the diameter of the drain line, the slope and the length of the drop (added velocity=greater siphon). 

guysAt the back of my jacuzzi, the installer did a shoddy job by not covering a 6 inch diameter hole for the electrical wiring - we've seen mice droppings there.

This street drain has a large (probably 3 feet in diameter) culvert that runs right under the property to a  large concrete drainage ditch behind the house.

wells are priced of course by a few things.diameter of the bore.depth of the hole..what type of material they are going throughand how much casing. so just check around and get price for diameter and depth then check well logs if they are public for surrounding properties to see how deep the water table is.keep in mind you can have a dry hole move over 200 feet and hit a geyser.My daddy always used a douser local tribe members are some of the best dousers.

The house has a raised foundation and the crawlspace is pretty clean, but the ground is soft In a circle with at least a 12 foot diameter.  

Roof issues going on for many years with leaks, our parking lots are breaking up and one is sinking in the ground by 24" deep and 20 foot diameter.
