How far from the main house were outhouses usually located?
Outhouses were common when running water was not available. Back then, outhouses were usually between 50 and 150 feet from the main house and often facing away.
Where is a water regulator located in the water line to your house when it is not by the water main?
The main vacuum unit is usually located in the basement with tubes running throughout the house. The tubes run to each room and have a hinged cover. You insert the hose in the tube and the vacuum unit automatically turns on and you can suck up the dust. All you have to move is the hose and not the main suction unit.
