How deep is a sewer manhole?
Normal Manholes These types of manholes are typically about 150 centimeters or five feet deep. They are located in the sewer or storm water line and include a heavy manhole cover that is typically square or rectangular in shape.
Where does the sewer line go in a house?
The Sewer Line. Just to be clear about what we’re discussing here, a home sewer line is the big drain pipe (typically 4-inch) that runs from the bottom of main waste/vent stack (main drain) in the house, down under the yard, and into the city sewer main under the street.
What are the different types of sewer lines?
Similar to all typical house drain lines there are different types of common sewer lines. While the material required to install them is the same, typically extra heavy cast iron, they differ greatly in their purpose. They fall into three categories which are:
What kind of pipe do you need for common sewer line in NYC?
Extra heavy cast iron pipe is also typical for almost all house connections in NYC. When more than two houses share a common sewer line a clean-out manhole is required at the property line. Clean-outs installed every 100′ are typical. The clean-out type and size are shown on the approved plan detail, known as an attachment F.
Where is the cleanout plug on a sewer line?
Your cleanout may be a threaded plug at the end of a fitting or short length of pipe attached to the main drain (typically found in the basement or crawlspace). It could also be outdoors, evidenced by a plug or small manhole-like cover sealing the top of steeply sloping pipe that leads down through the ground and into the sewer drain pipe.
1 Combined sewer line. A combined house sewer line collects and combines the flow from both waste water and storm water into one combined line. 2 Sanitary sewer line. A sanitary sewer, as its name implies, solely takes the flow of sanitary water. 3 Storm sewer line. A storm sewer line is dedicated to taking in rain water of all sorts.
Where does the water go in a sanitary sewer line?

Is the sewer line in the House PVC or plastic?
A house drain is the horizontal main drain under your basement floor. In some areas the home sewer line itself is also PVC, or a different variety of plastic tubing. However, in NYC the house sewer line itself must still be extra heavy cast iron pipe.
Do you have to run a sewer line with less pitch?
It is advisable to use legal bends to alleviate extreme pitch in pipe entering a sewer trap. The other and more advisable option is to run the drain line with less pitch to avoid using unnecessary bends. All plumbing fixtures must be trapped individually so that there is a water seal after the drain outlet of the fixture.
