How to Install a Sewer Pipe Line the Right Way
Sewage pipes from your home to the main branch of your municipal sewer line are called laterals. An appropriately prepared and slanted trench is typically utilized for this kind of pipe installation that is 4 inches in diameter. The installation of a sewer lateral involves five key steps. Local code inspections are necessary for all installation details to be approved before sewer pipe installation in Bridgeport.
Calculate the Altitudes
Most importantly, sewer pipes' length and elevation (depth) are vital factors to consider during the construction process. Beginning at the residence's foundation, an ordinary sewer pipe is called the "main drain" pipe. The line will then drop to a point referred to as a tap, connecting to the primary or city branch. A laser level, GPS, or classic surveying equipment is utilized to determine and record elevations.
Determine the Gradient
The first slope estimations are based on the elevations and length of the pipe. The total elevation drop can be determined by subtracting the elevation at the end from the beginning elevation. Divide the total length of the pipe by the drop to calculate the slope.
If the pipe connects to the city main at six feet, the slope is 2 feet. This is the slope for the 80-foot pipe.
Two-hundred-five percent (0.025 percent)
In most areas, the minimum slope is 2 percent or 2 feet of descent for every 100 feet of running distance. If they follow the local building code, slight slopes that are slightly steeper will be accepted. Since liquids are more mobile than solids, a steep slope could cause blockages. Because of the low velocity created by a low slope, no drainage problems can occur.
Find the pit and place the Bedding.
A lateral sewer trench must be carefully excavated to prevent the soil from being disturbed in a way that isn't needed. It is vital to compact any soil that has been disturbed to avoid it from settling. A small trench is ideal in most cases, but accurate information about where the pipe will finish is essential. A more deep trench is necessary.
There must be an uncompacted and smooth base to the trench and the necessary slope. To ensure that the pipe stays sturdy over time, it is recommended to use a bedding material such as sand that could be put into the trench. Because sand can be much simpler to slope than dirt, it can be put on top of the slope that has already been set.
Install the Tube
The latest PVC sewer pipes are connected using gasket fittings or solvent glue. The standard domestic water lines are four-inch pipes. The municipal code defines the material for pipes and the dimensions.
Each pipe segment should be fitted with its bell (female end) with its back facing upwards to lessen the chance of leaks at the junction. According to city regulations, the pipe is connected to the mainline in the city. Most codes at the home end will require two or three cleanouts so sewer augers can be used to cleanse the pipe.
Complete the Diggings
The trench is backfilled once the sewer lateral is constructed and passes the final inspection. Using a layer of sand for the first layer of backfilling is normal. This protects the pipe and fills any gaps. The trench then gets filled with soil layers. The goal is to ensure that the soil won't fall back in the future.
Warning tape should be positioned over any dirt that has been compacted. If there are any excavations in this area, crews will be alerted about the position of the pipe.
