Septic backup

Septic system owners often discover a Septic backup when the toilet no longer flushes properly or sinks and showers are not draining.  Solving the problem is a process of elimination.  Calling a plumber or septic installer is not always necessary.  
Each type of septic system has their own failure characteristics.  Mechanical systems with pumps are much different than conventional systems primarily because of the electrical power requirements.  Not all septic systems need power to function however, the ones that do need power are more prone to show issues before gravity (non-mechanical) systems.
Some of the common solutions for these units are verifying the breaker power source is on and working properly. Power surges can trip breakers which interrupt the mechanical devices of the unit to operate properly and prevent the effluent from leaving the unit which can back the flow up in the plumbing.  Always verify the power is on and working before requesting a service call.

Conventional (standard) septic systems typically do not have mechanical devices which require power.  Therefore, the process of elimination for trouble shooting is different.  Common failures in these types of systems are roots in the basic components of the system itself such as inlet pipes to the tank, or outlet lines which lead to the drain field or in the drain field itself.  Verifying this condition can take a little more effort to identify but in some cases is necessary to resolve the problem.  

All Septic systems need to be pumped.  Any vessel that handles solids and debris from a structure will eventually fill to a point where it could prevent the flow of effluent.  The best way to prevent problems is to be preventative!.  Take the time to consult with a professional in the trade that can guide you if necessary or consult with you at the site to provide experienced knowledge to aid in saving you money long term.
