Triple J Services
The Heart of Your Pressure Distribution System
In Pike County, where challenging soil conditions and varied terrain are common, many homes rely on advanced septic solutions beyond the traditional gravity-fed system. At the center of these advanced systems lies the effluent pump.
While it may look identical to a standard sewage pump or grinder pump to the untrained eye, your effluent pump plays a distinct and critical role. It is the heartbeat of your pressure distribution system, responsible for moving pre-treated wastewater (effluent) from your dosing tank to your drain field. When this pump fails, your system doesn’t just stop working—it risks catastrophic flooding of your leach field, localized surfacing of wastewater in your yard, and thousands of dollars in damage to your property’s underground infrastructure.
At Triple J Services, we specialize in the diagnosis, repair, and replacement of high-head effluent pumps. As Pike County’s trusted septic experts, we combine precision plumbing skills with our excavation-led approach to ensure that your system isn’t just running, but is balanced, efficient, and protecting your family’s health.

Effluent vs. Grinder Pumps: Knowing the Difference
One of the most common misconceptions we encounter is the confusion between effluent pumps and grinder pumps. While both are submersible pumps found in septic systems, installing the wrong one can destroy your drain field.
The Effluent Pump
Location: Installed in the second chamber of your septic tank or a separate dosing tank.
What It Pumps: It handles effluent—wastewater that has already settled in the primary septic tank. This liquid is mostly clear (greywater) with very few solids (less than 3/4 inch).
The Job: Its primary function is distribution. It pushes water through small-diameter pipes in your drain field under pressure to ensure even absorption into the soil.
The Risk: Because it is designed for liquid, it cannot handle raw sewage. If solids carry over from the primary tank (due to lack of pumping), the effluent pump’s impellers can easily clog or burn out.
The Grinder Pump
- Location: Typically found in a basement ejector pit or a pump chamber before the main sewer line.
- What It Pumps: Raw, unscreened sewage (blackwater) directly from the home.
- The Job: It uses metal cutting blades to shred solids (toilet paper, waste, food scraps) into a fine slurry, allowing it to be pumped uphill to a main sewer line or septic tank.
- The Risk: You should never use a grinder pump to dose a standard leach field. The slurry it creates is so fine that it will not settle in the tank; instead, it remains suspended and flows out to the drain field, where it creates a biological mat (biomat) that permanently clogs the soil pores, leading to total field failure.

Understanding the "Dosing" System
To understand why your effluent pump is so important, you have to understand the system it powers. In a standard gravity system, water trickles into the drain field every time you flush a toilet or run a sink. However, in many parts of Milford, Dingmans Ferry, and Lackawaxen, the soil is too shallow or rocky for this trickle method.
Instead, we use a Pressure Distribution System.
Accumulation: Wastewater collects in the dosing tank until it reaches a specific level set by a float switch.
The “Dose”: The effluent pump activates and sends a high-volume “dose” of water into the drain field all at once.
Pressurization: This surge of water pressurizes the pipes in the field, forcing water out of small holes (orifices) along the entire length of the trench.
Resting: The pump shuts off, allowing the soil to drain and re-oxygenate before the next dose.
If your effluent pump is undersized or failing, it won’t generate enough pressure (or “squirt height”) to reach the end of the drain field lines. This means all the wastewater dumps into the first few feet of the trench, saturating that area while the rest of the field stays dry. Over time, this uneven distribution causes “creeping failure,” where your drain field dies one section at a time.
Common Failure Signs: Listen to Your System
Effluent pumps rarely fail without warning. Because they operate in a harsh, wet environment, electrical and mechanical components degrade over time. If you notice any of the following, call Triple J Services immediately for a diagnostic check.
1. The High-Level Alarm is Sounding
This is the most obvious sign. Your dosing tank is equipped with a high-water alarm float that sits above the “ON” float for the pump. If the water rises high enough to trigger the alarm, it means the pump has failed to activate despite the tank being full.
Immediate Action: Silence the alarm (usually a button on the panel) and reduce water usage immediately. Do not shower or run the dishwasher until a technician arrives.
2. Pooling Water Near the Dosing Tank
If you see wet spots or lush, green grass directly above your septic lids or the dosing tank, it may indicate a cracked discharge pipe. The pump might be running, but instead of pushing water to the field, it’s recirculating it into the ground around the tank.
3. Constant Cycling or Hum
- Constant Running: If you hear the pump running 24/7, the float switch may be stuck in the “ON” position, or the check valve may have failed, allowing water to drain back into the tank after every cycle.
- Humming but Not Pumping: If you hear a low hum/buzz but no water is moving, the pump is likely “airlocked” (trapped air preventing flow) or the impeller is jammed with debris.
4. Tripped Breakers
- If your pump trips the breaker the second it tries to start, the motor windings are likely shorted out or moisture has penetrated the electrical housing. This usually requires a full pump replacement.

The Triple J "Excavation-Led" Advantage
Why hire an excavation company for a pump problem? Because septic systems are underground, and often, the pump failure is just a symptom of a larger structural issue.
Many plumbers will simply swap out a burnt pump for a new one without asking why it burned out. At Triple J Services, we look at the whole picture.
Accessing Buried Tanks: Many older systems in Pike County have dosing tanks buried under 1-2 feet of soil without risers. We have the excavation equipment to safely dig up the lids without damaging the tank or your yard.
Fixing Settled Lines: If your dosing tank has settled (sunk) over the years, it can shear off the PVC pipe connecting the pump to the field. We can excavate the area, re-bed the tank, and repair the schedule-40 piping to prevent future breaks.
Check Valve & Union Assembly: We don’t just drop a pump in by the power cord. We build a proper disconnect assembly with a high-quality check valve and union. This ensures that water doesn’t flow back into the tank (saving the pump motor) and makes future service easier and cheaper.
Float Switch Configuration: We precisely set your tether lengths for the “ON,” “OFF,” and “ALARM” floats. Incorrect float settings are the #1 cause of short-cycling, which kills pump motors prematurely.

Proactive Maintenance: Prevent the Emergency
The best way to handle an effluent pump failure is to prevent it from happening. We recommend a service interval of every 2-3 years, ideally timed with your septic pumping.
Our Effluent Pump Maintenance Service includes:
Cleaning the Screen: We pull the pump and clean the intake screen. Even in a dosing tank, small amounts of hair, lint, and grease can accumulate and choke the pump.
Amperage Draw Test: We measure how much electricity the pump uses while running. A spike in amps is an early warning sign of bearing failure or motor drag.
Float Switch Testing: We manually trigger the floats to ensure they move freely and haven’t become coated in grease.
Check Valve Inspection: We listen for the “thud” of the valve closing to ensure it is holding back the pressure from the force main.
Why Professional Installation Matters
Replacing an effluent pump is not a DIY job. Aside from the obvious health hazards of working with septic waste, there are significant electrical and hydraulic risks.
Effluent pumps run on high voltage (often 220V) in a wet environment. Improper waterproofing of the wire splices can electrify the ground around the tank or cause a fire in your control panel. Furthermore, sizing the pump requires calculating the Total Dynamic Head (TDH)—the friction loss in the pipe plus the elevation gain to the drain field. If you buy a generic pump from a hardware store, it may not be strong enough to overcome the head pressure, resulting in zero flow to your field.
Trust the experts. Triple J Services ensures the right pump is selected for your specific elevation and system design.
