If you live in Lackawaxen, PA, or the surrounding Poconos, you likely enjoy a bit of elevation and beautiful, rugged terrain. While this makes for great views, it often makes traditional gravity-fed sewer lines impossible. That is where the grinder pump comes in. This hard-working piece of machinery is the heartbeat of your home’s wastewater system. However, it is also surprisingly sensitive to what you send down the drain.
Unlike a standard septic setup that relies on gravity, a grinder pump acts like a powerful garbage disposal for your sewage. It grinds up waste and pumps it uphill to a septic tank or a municipal sewer main. When it works, you never think about it. When it fails, usually because of a “forbidden” item, it can lead to messy backups, expensive repairs, and a lot of stress.
Triple J Services is here to help you avoid those “middle of the night” emergencies. We specialize in grinder pump repair and installation, and we have seen exactly what happens when the wrong items meet the pump’s blades.
Understanding How Your Grinder Pump Works
Before we get into the “no-go” list, it helps to understand the mechanics. Your wastewater—from the toilet, shower, and sink—flows into a holding tank buried in your yard. Inside that tank is the grinder pump. When the water reaches a certain level, the pump turns on. High-speed blades grind the waste into a fine slurry, which is then pumped through a small-diameter pipe.
The space between these blades is very tight. They are designed for organic waste and toilet paper only. Anything else can jam the impeller, burn out the motor, or create a “mop” that wraps around the shaft. Once the pump stops, the tank continues to fill until sewage has nowhere to go but back up your pipes.
The “Flushable” Wipe Myth
The single biggest enemy of the modern grinder pump is the “flushable” wipe. Despite what the packaging says, these wipes do not disintegrate like standard toilet paper. They are often made of synthetic fibers or plastic-reinforced paper.
When a flushable wipe enters your grinder tank, it doesn’t break down. Instead, it floats or sinks until it is sucked into the pump. Because these wipes are incredibly strong, they often wrap around the grinder blades rather than being sliced through. Over time, multiple wipes create a thick, rope-like mass that completely seizes the motor.
If you use wipes, always dispose of them in a trash can. This applies to baby wipes, makeup removal pads, and disinfecting wipes as well. At Triple J Services, emergency septic pumping calls are frequently caused by these non-biodegradable cloths.
Hygiene Products and Plastics
Your grinder pump is not a trash bin. Many common bathroom items are made of materials that the pump simply cannot process.
-
Feminine Hygiene Products: Tampons and pads are designed to absorb liquid and expand. This makes them a nightmare for grinder blades. They create massive clogs that can stall even the most powerful motors.
-
Condoms: These are made of latex or synthetic materials that stretch but do not break. They can wrap around the pump’s internal components like a rubber band, eventually causing a mechanical failure.
-
Cotton Swabs and Balls: The plastic sticks in Q-tips can jam the impeller, while cotton balls can bunch together to block the narrow discharge pipes.
-
Dental Floss: Floss is essentially a high-strength string. It wraps around the pump’s shaft and can cut through seals, leading to motor flooding and total system failure.
Kitchen Grease and Oils
Many homeowners think that because a grinder pump “grinds,” it can handle anything a kitchen disposal can. This is a mistake. Fats, oils, and grease (known in the industry as FOG) are devastating to septic components.
When hot grease goes down the drain, it eventually hits the cooler water in your outdoor holding tank. It solidifies into hard, waxy chunks. These chunks can coat the “float switches” that tell your pump when to turn on or off. If the float gets stuck in the “off” position because of grease buildup, your tank will overflow. If it gets stuck in the “on” position, the pump will run dry and burn out.
Always pour grease into a jar and throw it in the trash once it cools. For pipes already burdened by grease, Triple J Services offers high-pressure drain jetting (hydro-jetting) to clear out the buildup before it reaches your pump.
Harsh Chemicals and Solvents
Your grinder pump relies on certain seals and plastic components to remain watertight. Harsh chemicals can eat away at these materials over time. Avoid pouring the following down your drains:
-
Paint and Thinners: These are toxic to the environment and can damage the pump’s housing.
-
Strong Drain Cleaners: These are often highly acidic or basic. They can corrode the pump’s metal parts and seals.
-
Motor Oil or Gasoline: Never dispose of automotive fluids in your sewer system. They are a fire hazard and can cause permanent damage to the pump’s electrical components.
If you have a stubborn clog, it is much safer for your system to call for professional septic system inspections rather than pouring corrosive liquids into your tank.
Food Scraps and Solids
Even if you have a garbage disposal in your kitchen, you should limit the amount of food waste you send to your grinder pump. Items like coffee grounds, eggshells, and fruit pits do not dissolve. They settle at the bottom of the grinder tank, creating a layer of grit. This grit can act like sandpaper on the pump’s blades, dulling them prematurely and reducing the efficiency of the system.
Heavy solids also increase the frequency needed for septic tank pumping. The more solid waste you send down the line, the faster your system will reach its capacity.
Managing Laundry and Lint
Large amounts of lint from washing machines can accumulate in your grinder tank. This fiber often clumps together with grease to form “ragging,” which is a leading cause of pump blockages.
Consider installing a lint trap on your washing machine’s discharge hose. These inexpensive mesh bags catch the majority of fibers before they ever enter your plumbing. Additionally, try to spread out your laundry loads. Sending ten loads of water down the drain in one day can “slug-load” the tank, forcing the pump to work harder than necessary.

How to Spot a Grinder Pump Problem
Your grinder pump system is usually equipped with an alarm box, typically mounted on the side of your house or on a post near the tank. If the light is on or a buzzer is sounding, your pump is struggling or has failed.
-
Listen for Noises: If your pump sounds like it is “grinding rocks,” there may be a solid object stuck in the blades.
-
Slow Drains: If multiple drains in your home are slow, it usually points to a backup in the main line or the grinder tank.
-
Foul Odors: While some smell is normal, a sudden, strong sewage odor near the tank can indicate a leak or an overflow.
If you notice any of these signs, stop using water immediately and call us. Continuing to run water will only make the backup worse.
Protecting Your “Turkey Mound” or Leach Field
If your grinder pump pushes waste to a raised leach field—often called a “Turkey Mound” in Pennsylvania—maintaining the pump is vital for the health of the field. If the pump fails to grind the waste properly, larger solids can enter the leach field (“Turkey Mound”), clogging the distribution pipes and leading to a much more expensive repair.
A healthy pump ensures that only finely ground slurry reaches your treatment area, extending the life of your sand mound and keeping your property environmentally compliant. For more on how to manage these systems, you can visit the Environmental Protection Agency (EPA) Septic Guide, which offers excellent resources for homeowners.
Preventive Maintenance is the Best Cure
We recommend a professional inspection of your grinder pump every year. During an inspection, we can:
-
Clean the Tank: Removing accumulated grease and grit.
-
Check the Blades: Ensuring they are sharp and free of debris.
-
Test the Floats: Making sure the pump turns on and off at the correct levels.
-
Inspect the Alarm: Ensuring you will be warned before a backup occurs.
Regular maintenance costs a fraction of the price of a total pump replacement. In many cases, we can catch a small issue—like a worn seal or a tangled float—before it turns into a total system failure. You can also check out the National Association of Wastewater Technicians (NAWT) for more information on the standards of care for residential wastewater systems.
The Reality of Pump Replacement
Even with perfect care, grinder pumps eventually wear out. Most high-quality pumps have a lifespan of 8 to 12 years. When it is time for a septic system installation or replacement, Triple J Services can help you choose a pump that is sized correctly for your home’s needs.
Modern pumps are more energy-efficient and offer better grinding capabilities than older models. We handle the entire process, from excavation to electrical hookup, ensuring your new system meets all local Lackawaxen codes and regulations.
