It was a 3/1/2 had gravity fed heat for the first floor & no heat upstairs, it had one 3/4 bathroom (that a 6 foot tall person could not stand up in the shower) and it would need to be significantly remodeled. 

Steam was fed up the line into the radiator, and then would recondense to condensate and return back down the same pipe via gravity to the condensate station or pump.

Since sewage relies on gravity to drain you can't really install new waste lines below the grade of the existing lines.

Using very simple concepts, Newton was able to put together laws for how time, gravity, mass, energy, momentum, etc all played together nicely.

The palmer valve had a gravity check valve on it that allowed the water to flow into the sewer, but did not allow sewage to backflow into the drain tile.

I wait until I have gained legal possession and let gravity go to work.

If you are in an area where you know a complete replacement with a gravity septic system will be fine you can estimate that. our area and parts of MA a newer higher cost pump system can be required for wetlands areas and if you have an old cesspool replacement with septic is required.

& in New York we have the dreaded Scaffold Law that has ruined many businesses & home owners.....take adequate precautions.The Scaffold Law, enacted in 1885 as Labor Law 240, places almost absolute liability on contractors and property owners for gravity-related accidents at construction sites, even when the workers are at fault in part or whole.

If brushing, grab the data sheet from SW or online and it will tell you how to thin/retard the paint to extend the dry times and thickness to help with gravity evening it out before fully drying.  

They sat at a computer, like you are now, but instead of learning about real estate they learned about gravity and the degradation effects of ultraviolet light.
