INSTALLATION INSTRUCTIONS (cont’d) Secure 5/8" vent hose, 1 ½" holding tank inlet hose, 1 ½" dockside discharge hose, and 1 ½" overboard discharge pump hose (optional). SeaLand recommends that all 1 ½" hoses be secured with double clamps to prevent any leaks that may occur if the fittings are undersized.
INSTALLATION INSTRUCTIONS (cont’d) CLEANING A small amount of water remains in all marine holding tanks. It is good practice to rinse the tank after the contents have been discharged. This can be accomplished by adding water to the toilet bowl. Add 8 ounces (237ml) of SeaLand Holding Tank Deodorant and Cleaner to the bowl. Flush the entire contents into the holding tank and continue flushing until the discharge from the holding tank is clear.

HOLDING TANK DISCHARGE INFORMATION OVERBOARD DISCHARGE When is it okay to discharge overboard? The answer to this question depends on where you are boating. If you are three miles or more offshore in U.S. coastal waters, you can legally discharge untreated effluent from the holding tank. Within three miles of shore, however, it is not legal to dump raw sewage into the water.
