M-1 Tanks offers a comprehensive range of tank accessories designed to enhance the functionality, maintenance, and performance of your septic system. Our accessories are engineered for durability and seamless integration with our tank products. Risers: Our high-quality risers provide convenient access to underground tanks, bringing access points to ground level for easier maintenance and inspection. Available in various heights and diameters, our risers can be customized to meet specific installation requirements. Biotube Filters: These essential components help prevent solids from entering the drainfield, extending the life of your septic system. Our biotube filters are designed for efficient filtration while requiring minimal maintenance, featuring easy-to-clean designs that simplify routine service. Adapters: Concrete adapters are specifically designed to work with 24" ultra rib pipe. Often times the access to septic tanks are too large for the 24" pipe to sit on. Older tanks will need modified concrete adapters to sit on top of the tank and bush down to fit the 24" riser pipe. M-1 Tanks carries both a 34"(outside diameter) round adaptor and a 39" x 34.5" square adaptor with a round center. All our tank accessories are manufactured using high-quality materials that resist corrosion and degradation in the harsh septic environment, ensuring long-term performance and value for your investment.
