A primary sewer cleanup is typically connected to the underground main sewer line. The pipe typically forms a horizontal line starting from the main line to the floor and extending up to ground level. The access hole is usually found outside of the building or residence and often covered by a cap. In some cases, a cover plate is added to add additional protection and aesthetics.
There are times when the main sewer is so large that it will need to be divided into a smaller drain field. This is accomplished by a series of smaller pipes that feed into an external drain field. An external sewer cleanout can be used in situations when your local sewer system is inadequate. In this case, you need to install an external sewer line or system to remove all of the waste from your building.
An external sewer line can also be used to create a bypass system. The main sewer may have been clogged with debris, leaves, and other material, causing blockages and back flow of sewage. An external system can then be placed between the main line and the building for a clean bypass. In most cases, the system has a sensor that will shut off water flow if the blockage is detected. When you are performing a sewer cleanout you may be required to run water through a hose into a separate section of the area to be cleaned.
Another type of drainage system is a combined sewer drain system. These systems combine both an internal and external sewer line to create a single system. The entire system runs from a sewer main pipe to the exterior drain field. As water is drained from the pipe into the drainage field, a discharge valve is closed on the external pipe, allowing the wastewater to drain away from the area. Some systems have a remote control valve to activate the discharge valve for you.
Once you have completed the sewer drain field you will want to empty the sewage and any other liquid matter from your floor drains. This may involve removing tree roots, and brush from around the edges of the floor drain field. After the drainage field has been emptied, you will be able to use a pump to push the accumulated material into a new drain field. You may also need to clear away leaves, branches, twigs, and sticks on the walls, flooring, ceiling, and ceilings to make the room for your new system.
It is important to note that an outside sewer cleanout should be installed only where there is no main drain field that will allow for back flow. This will prevent damage to the soil and the foundation of the structure as well as the damage to the existing structure will allow for back flow of sewage back into the main drain field.
