This 500 gallon septic pump tank is designed for underground installation and built to handle the demands of residential and light commercial wastewater systems. Constructed from polyethylene using an ANSI/NSF 61 approved resin, it arrives preplumbed with a 4'' gasketed PVC inlet pipe and a 4'' gasketed PVC tee outlet assembly, saving installation time and reducing the need for additional fittings on site. The single-compartment design keeps the workflow straightforward, while the 20'' manway cover provides convenient access for inspection and servicing once the tank is in place.

At 60'' W x 60'' D x 63'' H, this stationary tank fits standard underground pump chamber applications and is rated for liquid temperatures up to 130 degrees F (54 degrees C). The grey polyethylene construction resists corrosion and stands up to the underground environment without the maintenance concerns associated with concrete or metal alternatives.

A septic pump tank is used downstream of a primary septic tank to collect effluent and pump it to a drain field or secondary treatment system on a timed or demand-driven cycle. This tank fits that role as a dedicated pump chamber, keeping the pumping stage separate from the settling stage for a cleaner, more controlled system. Installers working on properties with challenging topography or elevated drain fields will find the preplumbed configuration particularly useful, since the inlet and outlet connections are already in place and ready to tie into the system. The 20'' manway cover allows a technician to access the pump and float controls without excavating the full tank footprint.

Key Features:

• 500 Gallon Capacity: Sized to serve as a dedicated pump chamber in residential and light commercial septic systems, providing adequate holding volume between pump cycles.
• Preplumbed Inlet and Outlet: Ships with a 4'' gasketed PVC inlet pipe and a 4'' gasketed PVC tee outlet assembly already installed, reducing field labor and connection time.
• ANSI/NSF 61 Approved Resin: The polyethylene resin meets ANSI/NSF 61 standards, supporting use in systems where material safety and resin quality are required by code or specification.
• 20'' Manway Cover: The included manway lid provides direct access to the tank interior for pump installation, float adjustment, and routine service without full excavation.
• Underground-Rated Stationary Design: Built specifically for below-grade, stationary installation and rated for liquid temperatures up to 130 degrees F (54 degrees C).
• Single-Compartment Construction: One-compartment layout with gasket-and-tee plumbing keeps the pump chamber function clear and the installation straightforward.

This 500 gallon polyethylene septic pump tank is a practical, ready-to-install solution for underground pump chamber applications. The preplumbed connections, ANSI/NSF 61 approved resin, and accessible manway cover make it a well-specified choice for contractors and property owners setting up or replacing a septic pump stage.
