“No Discharge” is no problem with new pre-assembled holding SeaLand tank systems. With five popular tank sizes, boatbuilders can easily outfit 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 five new holding tanks are pre-plumbed with inlet and discharge fittings, a vent fitting, 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 fittings rotate to accommodate virtually any plumbing layout. Inlet and discharge fittings 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 fitting, plug, sealing grommet and hose lubricant for easy hose attachment. 

SeaLand DHT-L series holding tanks are sized to fit on the most popular boat models and lengths.
