Trionic Super Premium Holding Tank - 20 Gallon

Odor free and leak proof.
This tank is rotationally molded to form a seamless, one piece, non-corroding, virgin linear polyethylene unit that meets FDA CFR 177.1520 and Coast Guard regulations.

Top mounted hose connections eliminate sewage standing in discharge hose - which is the major cause of odor permeation through the hose.
An elevated vacuum relief valve with easy clean screw cap prevents tank from collapsing when using dock pumpouts with high levels of vacuum, or if the tank vent should be clogged.
This tank is guaranteed to be extremely durable.

• Overbuilt, stiff, full 3/8" wall thickness - won't allow odors to permeate
• All fittings mounted on the top of the tank - no leaks, no standing sewage in hoses
• 1-1/2" barbed inlet port (can be rotated to any position)
• 1-1/2" barbed outlet port for pumpout (can be rotated to any position)
• 5/8" barbed vent port (can be rotated to any position)
• 3" inspection port with screw cap
• Vacuum relief valve - with screw cap for easy cleaning, if necessary
• Complies with U. S. Coast Guard requirements
• An additional 1-1/2" discharge fitting can be added (by special order) for direct overboard discharge only where it is legal - eliminating the need for a "Y" valve

Note - Add 3 inches to overall tank height to accommodate fittings.
Tank bottoms should be fully supported when installed; connect using flexible hose

Dimensions - 24"L x 16"W x 12"H
