The Trionic Super Premium Marine Holding Tank is engineered for long-lasting, odor-free performance in even the harshest marine environments. Constructed from 100% virgin 3/8” wall polyethylene, this tank offers exceptional strength, leakproof reliability, and resistance to corrosion and odor permeation.

Designed for superior sanitation and ease of maintenance, the tank’s top-mounted hose connections eliminate sewage from standing in the discharge hose — a primary source of odor permeation in conventional systems. A raised vacuum relief valve with an easy-clean screw cap prevents tank collapse during high-vacuum dock pumpouts or when vents become clogged.

Each Trionic Super Premium Tank comes complete with precision-molded fittings and hardware for reliable operation and serviceability.

Includes the following fittings:

  • 1/2” NPT x 5/8” barb vent assembly

  • Inspection port

  • 1-1/2” inlet

  • 1-1/2” outlet (pumpout)

  • Vacuum relief valve

All inlet, outlet, and vent fittings are rotatable for flexible installation. An optional overboard discharge is available for an additional $30.

Dimensions:

  • Length: 24 in

  • Width: 14 in

  • Height with fittings: 13 in

This tank is odor-free, leakproof, and built to meet or exceed U.S. Coast Guard requirements, ensuring compliance, safety, and reliable long-term service.
