This is installed in the outlet of the tank and helps prevent anything other than liquid getting into the leach field or clogging the outlet pipe.

Clogged septic tank filter.

Signs may include toilets backing up and slow draining sinks. If the septic filter at the septic tank is clogged effluent is being discharged abnormally slowly through it to the drainfield which gives the drainfield a relief but is abnormal. The effluent filter is a plastic cylinder in your septic tank s outlet pipe that prevents solid waste from escaping. Open the access lid on the tank that s furthest from your home.

Clean the effluent filter on the outlet pipe to improve drainage. Your septic tank outlet filter needs maintenance just like the rest of your septic system. Water treatment equipment can cause septic filter clogging or fouling a third cause of any type of septic filter or effluent filter clogging is overloading from ancillary water treatment equipment. Proper septic tanks should be fitted with an effluent filter or tank outlet filter.

Even a well maintained functional septic tank outlet filter will eventually become clogged as effluent leaves the tank and travels to your drainfield. A properly working septic tank outlet filter will become clogged as effluent is filtered and leaves the septic tank. If a filter is clogged or partially clogged it may not be letting the effluent water from the tank flow into the drain leach field. As the solid materials accumulate over time they progressively clog more and more of the filter requiring maintenance.
