What is a Zabel filter?
Zabel’s patented filter design reduces and traps solids in the filter by allowing them to slough off and fall back into the tank for further digestion. Slots rather than mesh screens provide less surface area for solids to attach and promote the sloughing action.
Are effluent filters necessary?
Your septic will function normally without an effluent or wastewater filter. However, if your intentions are to reduce premature repair and replacement of the leach field, then you should definitely install an effluent/wastewater filter.
How often should I clean my effluent filter?

Under normal conditions, your effluent filter will function for several years before cleaning is necessary. At a minimum, the filter should be cleaned whenever the tank is pumped, at least every 3 to 5 years.
Why does my septic tank have a filter?
Filters are usually located in the septic tank near the end where the effluents leave the tank and flow to the leach field. A filter will help trap small particles of suspended solids and particle matter that was not caught in the portion of the tank where the majority of the sludge and scum is found.
Why does my effluent filter keep clogging?
The most common reason for why the effluent filters are clogged is that there is too much wastewater being generated in too short a period of time. If this happens, the abundance of wastewater will create some type of turbulence within the septic tank.

Where is the effluent filter located?
septic tank
An effluent filter is a filter that is installed on the drain side of your septic tank. It helps to keep any solid waste from flowing out of your tank, causing problems in your drain field or leading to failure or clogs in your outgoing septic tank line.
How do you tell if the leach field is clogged?
Stay vigilant for five signs your drainfield does not drain correctly anymore.
- Slowing Drainage. Homeowners first notice slower than usual drainage from all the sinks, tubs, and toilets in a home when they have a compromised drainfield.
- Rising Water.
- Increasing Plant Growth.
- Returning Flow.
- Developing Odors.
