Proper maintenance and operation of a septic system rely on more than just the tank itself—quality septic tank accessories are essential for a well-functioning and long-lasting system.

Our selection of septic tank accessories includes everything needed to optimize system performance, durability, and accessibility.

Types of Accessories and How They Add Value to Your Septic System

A robust septic system is composed of various components, each playing a specialized role to keep wastewater treatment effective and safe. Septic pumps facilitate wastewater movement and oxygenation, breaking down solids and transferring treated wastewater to the drain field. Risers make above-ground access possible, simplifying regular inspections, maintenance, and pumping. To secure your system, septic lids provide durable tank covers, while alarms continuously monitor system performance, alerting you to potential issues like overflows or pump failures.

Components like distribution boxes and chambers ensure balanced and effective wastewater dispersal into the soil, critical for systems of all sizes. Float switches and control panels provide automated management of wastewater levels and pump cycles, preventing overloads and maximizing system efficiency. Septic gaskets, crafted from durable rubber or plastic, help seal critical connections, keeping your system airtight and leak-free. These septic tank accessories collectively enhance wastewater treatment and contribute to environmental protection by ensuring that your system operates as intended.
