Holding Tank System
“No Discharge” is no problem with new pre-assembled holding SeaLand tank systems.
With ve popular tank sizes, boatbuilders can easily outt any boat in their line with
a high-quality holding tank, and assure customers of long-lasting performance and
efficiency.
Available in capacities of 11, 16, 23, 29, and 36 gallons, SeaLand’s ve new holding
tanks are pre-plumbed with inlet and discharge ttings, a vent tting, inspection port and
pressure relief valve. Each “plug ‘n play”-style tank is pressure-tested and ready to install
– just bolt it down, fasten the hoses, and hit the water.
High-strength polyethylene tanks feature a heavy-duty wall thickness of 0.25-inch
to maintain integrity even under high pressure, and to avoid permeation of tank wall
with waste odor. Built-in mounting “feet” allow fast, secure bolting to the hull without
restraining straps. Top-mounted inlet, discharge and vent ttings rotate to accommodate
virtually any plumbing layout. Inlet and discharge ttings accommodate 1.5-inch ID
sanitation hose, but can be adapted to other plumbing system dimensions. Also included
with each tank are an extra inlet tting, plug, sealing grommet and hose lubricant for
easy hose attachment.
SeaLand DHT-L series holding tanks are sized to t on the most popular boat models
and lengths.
