Clogged septic tank filter.
How often should you clean a septic filter.
Your septic tank outlet filter needs maintenance just like the rest of your septic system.
The effluent filter is a plastic cylinder in your septic tank s outlet pipe that prevents solid waste from escaping.
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.
Even a well maintained functional septic tank outlet filter will eventually become clogged as effluent leaves the tank and travels to your drainfield.
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.
Build up of solid waste in your septic tank filter simply means your filter is functioning as it should.
As the solid materials accumulate over time they progressively clog more and more of the filter requiring maintenance.
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.
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.
Signs may include toilets backing up and slow draining sinks.
Then the tank and sewer line may not drain properly and back up.
