How to Install a Perforated Sewer Drain Pipe

Sewer perforation-Usually made of PVC in modern systems-Buried in gravel in an underground trench below the level of the septic tank.The septic tank is a pre-treatment part of the septic tank system in which bacteria digest the septic tank solids.The tank releases partially treated liquid and flows along a closed pipe to the septic tank or drain field.When the height of the septic tank is lower than the tank, the pipes in the septic tank and septic tank must be horizontal.The authorities that allow your county or city must sign your plan before you install the septic tank system, and the plan of the project will show the elevation and layout of the perforated pipe trench.Dig out the depth, width and configured soil you need for your approved plan in the trenches.Each floor plan is specific to the property to be built and depends on the size, shape, natural slope and soil composition of the property, as well as the penetration rate of water through the soil and the size of the family that the system serves.The ground of the Trenches ditch should be as close to the level as possible so that the wastewater is evenly distributed throughout the system.Use backhoe or similar excavation equipment in this work.Put 6 to 12 inch gravel at the bottom of the trench.Select the gravel with a diameter greater than the hole in the perforated tube.Your municipality may have specific requirements for the type of gravel you must use, the depth of gravel that the perforated pipe must be installed.Lay perforated pipe fittings on top of gravel, most of the holes point down and self-connect them with PVCpriming glue.The pipe part is made with a connecting flange at one end of each pipe, so the next pipe will slide inside the previous pipe.Before the glue has a chance to dry, apply the PVC glue to the inside of the female flange and the outside of the male end and quickly slide together;Make sure that the perforated holes all point in the same direction.Cover any end of the pipe with a bonded PVC cap.Not all leach field plans have terminals on the pipeline.Place a height over the long distance of the PVC and adjust the level of the pipe by swinging on the gravel and pushing the high part until the bubbles are in the middle of the glass at the height.You can add gravel under too low pipes.You can also use a transit layer or a laser layer to place your pipe and some municipalities actually ask you to do so.The introduction end of the perforated pipe is bonded to the joint on the non-perforated PVC pipe flowing out of the system distribution box.The distribution box ensures that the wastewater is evenly distributed across multiple lines of the perforated pipe.Place about 6 inch of gravel on the pipe and be careful to avoid interfering with the pipe placement.Your municipality may need to check before you do so.Cover gravel with single layer geologyTextile fabric to help prevent soil from infiltrating gravel and fill ditches with soil on the remaining roads.GravelGeo-Textile manufacturers level, laser level or transport level pvc self-Avoid straying from the plan approved by your licensing agency.If you do not follow the plan during the installation process, the final product, county or city will not be approved, and may even let you tear it off.Avoid planting trees or other plants with invasive roots on or near the drainage site.The root can grow into a perforated pipe and follow it all the way to the septic tank, completely blocking the system.
