Not exactly a sewer main normally flows by graviety and a forced main is a pumped system
A leak in the slab is an under ground stream or broken line under the slab. It is NOT the same as a belly in a sewer line.
no.
If you have a basement, you can see where the line goes through the wall. It is probably a straight line from that point to the street or alley depending on where it is. If in a group of track houses, it may angle to the property line and those two house will run in the same ditch. It can be anyplace, there is no set place it has to be, only the depth. If you don't have a basement, you can use the same directions and go from the main vent in the roof.
ABOVE the sewer line and on an angle away
Yes, but with certain requirements as the water piping has to be higher then the sewer line among other code items
Same as any other .25 per foot
The problem could be anything from a small ball thrown down the drain, to roots clogging up the sewer line, to a cracked sewer line, all of which have been known to block sewer lines. Best bet is to dig down where the rods end and investigate the problem
Clog between there and the city sewer or the main line has collapsed or has tree roots growing into it. Probably time to call the plumber. Thanks, it turned out to be a block drain. We are having some work done and the builder had filled a redundant washer washer pipe with expanding foam, trouble is, he filled the drain to the main sewer at the same time, thanks again
You apparently have a creative drain system in your house. Your kitchen sink and your bath tub drains are tied together on the same branch flowing to your main line. I am assuming the toilets are not bubbling or overflowing when the kitchen sink drains. If they are, your main sewer line is clogged. If not, you need to have someone (preferably a plumber) run a cable or snake, as some people call it, through the kitchen sink drain.
"The condition of equilibrium or motion of a rigid body is remain unchanged, if a force acting on the rigid body is replaced by another force of the same magnitude and same direction but, acting anywhere along the same line of action."
The line of action refers to an imaginary line in the same direction as a force acting on an object. It helps determine the direction in which an object will move or rotate when a force is applied to it. Understanding the line of action is important in analyzing the effects of forces on objects.
YES, you do need a trap. Usually the bathtub drain is on the same sewer line as the nearby toilet.The smell from the toilet's discharge will sneak up through the bathtub's drain line without a trap ... not pleasant!.
