How Often Should the Septic Tank Outlet Filter Be Cleaned?

Clogged DrainfieldA clogged drainfield is one of the most common (and expensive) causes of septic system failure. However, a septic tank outlet filter can be a simple solution to help you avoid clogged pipes in your drainfield. A septic tank outlet filter, also known as an effluent filter or grey water filter, protects your septic system by filtering effluent as it leaves the septic tank.

Screening Device

The screening device, made of slotted plastic, is installed in the outlet of a septic tank and helps prevent anything other than liquids from getting into (and potentially clogging) the drainfield. The slots are small enough that it allows the liquid to pass through while the larger solids will remain.

Why Does The Outlet Filter Become Clogged?

A properly working septic tank outlet filter will become clogged as effluent is filtered and leaves the septic tank. As the solid materials accumulate over time, they progressively clog more and more of the filter, requiring maintenance. Your septic tank outlet filter needs maintenance just like the rest of your septic system. They should also be cleaned when you get the tank pumped and cleaned.

When Should The Outlet Filter Be Cleaned?

When Should The Outlet Filter Be CleanedSeptic tanks need to be periodically pumped out to remove sludge and scum which do not break down quickly with the normal digestive processed in the tank. 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. Learn more about FloHawks’ recommended maintenance.

Septic tank maintenance is best left to trained FloHawks service technicians. The septic tank outlet filter should be removed from the septic tank and the solids need to be thoroughly removed. Once it’s clean, the outlet filter should be placed in the correct place and reinserted properly back into the septic tank.

What Happens If The Outlet Filter Isn’t Cleaned?

Without regular maintenance of the outlet filter, sewage could back up into your home. Slow drains and gurgling noises coming from your plumbing system are indicators that your septic tank needs a good cleaning and some routine maintenance. It is best to contact a trained professional to install a new filter or clean or replace an existing one.
