Many homeowners don’t know their septic tank. The tank is buried and forgotten, along with the rest of the system, until sewage is ankle deep in the basement or bubbles up in the yard. Then, the septic tank system is unfairly criticized for failing to do its job.

How many people would buy an expensive car and never change the oil? Similarly, regular maintenance of your septic system is necessary to ensure it’s proper operation.  Over time the solids will just naturally build up over time in the septic tank.  When the septic tank gets full, the solids can start to flow into the pipes leading to the drain field.  The solid particles will really cause problems in the drainfield, by not allowing the liquids to properly filter through the drainfield.  That is when the liquid starts backing up in the pipes and now there are slow drains and/or other problems.

Regular septic tank pumping is the best preventive maintenance you can do for a septic system.
