A septic tank can be an important part of a home drainage system, helping in the treatment and elimination of wastewater. Septic tanks may often have to be replaced for reasons such as damages incurred to the tank or the age of the unit. When choosing the best septic tank replacement, some of the things you may want to consider are the different types of septic tanks, materials, and any professional companies that may provide replacement and installation services.
Septic tanks generally are located underground, at a safe distance from residential property, and away from any freshwater sources. Septic tanks are connected to waste drainage system such as toilets by a series of pipes. Wastewater from the building structure is carried to the septic system through these pipes, where it usually remains in the tank for a period of 24 hours. After natural bacteria in the tank assists in the decomposition of the waste, it is discharged from the tank. Septic tanks are common in areas where there is no connection to sewer pipes.
When a septic tank deteriorates over time or is damaged, it no longer can contain water. This leakage may prevent the septic tank from sufficiently decomposing the waste stored inside it. When this occurs, septic tank replacement usually is recommended.
Familiarizing yourself with the different types of materials from which the septic tank is made can help ensure that the replacement tank will last for a long time. Steel septic tanks may be more susceptible to rust, while concrete and plastic septic tanks generally are considered to have a longer life span. Experts estimate that a concrete or plastic tank can last for up to 40 years.
All septic tanks typically should have an installation guide included with the product. It can be a good idea to request a look at the installation guide before you purchase the septic tank at a septic tank dealer. This can help you determine how difficult or demanding the installation of the replacement tank could be.
Sometimes the best option for septic tank replacement may be to purchase the same brand of septic tank as the one you intend to replace. This generally should allow for an easier installation process, since the waste pipe system already is fitted for the septic tank you have installed. It may also prevent you from having to make any adjustments or changes to the piping system that connects to the tank.
Many contractors offer septic tank replacement services. They typically will offer a price that includes the cost of the septic tank and the labor necessary to install it. This can be a good option if you do not want to concern yourself with the replacement and installation process. In general, these companies will dig a hole to install a septic tank and connect it to the existing drainage system. They also may fill the old septic tank with dirt and properly dispose of it.
