Marine Holding Tanks Go Head-to-Head
A former PS pick, SeaLand tank squares off against new tank from Trionic.
In our 2002 holding tank test, SeaLand emerged as the winner. The material of choice for holding tanks continues to be rotationally molded linear polyethylene, which is light in weight, doesnt corrode, allows for seamless tank construction, is relatively inexpensive, and wont allow odors to permeate. This new test compares a pre-2009 model SeaLand tank to a new holding tank from Trionic Corp. The holding tank test looked at the tanks construction materials, price, size, valves, inlets, outlets, leaks, inspection ports, vent size, warranty, and performance-based panel deflection. Preventing threaded fittings from leaking was the hardest part of the test.
