Septic Tank Filter Cleaning in Evesham, NJ
A Dirty Filter Puts Your Whole Septic System at Risk
Your septic tank has a small screen called an effluent filter. It sits at the outlet baffle and catches solid particles before they leave the tank. When that filter clogs, wastewater has nowhere to go. Drains slow down, toilets gurgle, and sewage can back up into the house. The Sewer Kings keeps your filter clean so your system flows the way it should.
We provide filter cleaning as a standalone service and as part of routine septic system service visits. Our crew pulls the filter, hoses it down, inspects it for damage, and reinstalls it on the spot. If the filter is cracked or worn out, we carry replacements on every truck.
Most homeowners do not even know their tank has a filter. That is a problem because these screens need cleaning every one to three years. If yours has never been touched, it is likely restricting flow right now. One service call fixes the issue and prevents bigger problems down the road.

What a Septic Tank Filter Does and Why It Matters

Inside your septic tank, wastewater separates into three layers. Solids sink to the bottom as sludge. Grease and oils float to the top as scum. The liquid in the middle – called effluent – flows out to the drain field. The effluent filter sits right at the outlet pipe and screens out small particles that remain suspended in that liquid.
Without a filter, those particles travel into the drain field pipes and soil. Over time, they form a thick biological layer called biomat. Biomat seals the soil and stops water from draining. Once a drain field reaches that point, the only fix is a full replacement that can cost $10,000 or more.
The filter acts as the last line of defense. It traps particles as small as 1/16 of an inch and keeps them inside the tank where they belong. But the filter only works when it is clean. A clogged screen blocks effluent from leaving the tank entirely. That creates the same backups and damage you would see from an overfull tank.
How We Clean Your Septic Tank Filter
Our crew starts by opening the access lid over the outlet side of the tank. We pull the effluent filter straight up from the baffle housing. Some filters slide out easily. Others are stuck with years of buildup and need careful removal to avoid dropping debris back into the tank.
Once the filter is out, we rinse it with a high-pressure hose directly over the open tank. All the trapped solids wash back into the tank where they will be removed during the next pumping. We inspect every surface of the filter for cracks, warping, or broken fins. A damaged filter lets particles slip through and defeats the purpose of having one.
After cleaning, we reinstall the filter and check that it seats properly in the housing. A loose filter shifts out of position and creates a gap where solids escape. We also check the outlet baffle itself for cracks or corrosion. In older Evesham homes, concrete baffles deteriorate over time and need replacement. We handle that repair on the same visit if needed.

Signs Your Septic Tank Filter Needs Cleaning

Slow drains throughout the house are the most common sign. When every fixture drains slowly at the same time, the problem is not in a single pipe. It is a flow restriction at the tank. A clogged filter is one of the most frequent causes of this symptom in homes with newer septic systems.
Sewage backing up into floor drains or tubs means wastewater has nowhere to go. The tank is receiving water faster than it can discharge. In many cases, the tank itself is not full – the filter is simply blocked and choking the outlet. This backup can happen suddenly and without warning.
A high-level alarm going off on your pump tank can also point to a filter issue. If effluent cannot leave the septic tank, the pump chamber downstream runs dry or overflows depending on the system layout. Before replacing a pump or float switch, a good technician checks the filter first. It is a simple fix that gets overlooked.
Gurgling toilets and wet spots in the yard round out the warning signs. Gurgling happens when air gets trapped in pipes due to restricted flow. Wet spots near the tank area suggest effluent is surfacing because it cannot exit through the normal outlet path.
When to Clean or Replace Your Effluent Filter
Most effluent filters need cleaning every one to three years. The right interval depends on your household size, water usage, and how quickly solids build up in the tank. A family of five with a garbage disposal will clog a filter much faster than a retired couple with low water use.
We recommend combining filter cleaning with your regular pumping schedule. When we pump the tank, the filter gets cleaned at the same time. But some homes need filter service more often than pumping. If you notice slow drains between pump-outs, a standalone filter cleaning solves the issue without the cost of a full pump.
Replacement is necessary when the filter body is cracked, warped, or missing fins. Plastic filters degrade over time from constant exposure to wastewater gases. We carry the most common filter sizes on our trucks and can swap a bad filter in minutes. If your tank does not have a filter at all, we install one during any service visit. It is one of the cheapest upgrades you can make to protect your drain field.
