seacock. The system is easy to operate and with correct usage and proper maintenance, will provide many
years of use.
IMPORTANT - Owners should familiarize themselves with all local and federal regulations
regarding proper discharge and avoid inadvertent discharge at all times.
Before operating the HEAD , ensure you have read its manual thoroughly and understand the proper
procedures. Silly mistakes can cause severe “head” aches at the worst possible time! And a word to the wise
PLEASE TRAIN YOUR GUESTS ON HEAD OPERATION.
NEVER ASSUME THEY KNOW HOW TO USE IT.
The head is a large pump which takes in seawater and flushes waste into the holding tank. The water intake
and discharge seacocks are located under the V-berth and galley sink respectively. Remember the
open/closed positions on these thru-hulls. It is good seamanship to close both the intake and discharge
seacock when not in use.
When seawater and effluent are pumped through the head, they’re pumped into the holding tank by the action
of pumping the toilet handle. The waste discharge fitting on deck is provided so a pump-out station can empty
the tank. Care should be taken not to overfill the holding tank as effluent can block the vent hose and may
damage the tank... or worse, burst the hose. If the toilet is difficult to pump, check to see if the holding tank
is overfilled. “When in doubt, pump it out!” A great resource for understanding and maintaining a marine
head system is a book called “Get Rid of Boat Odors” by Peggie Hall - Seaworthy Publications.
Recommended cleaning solutions:
Holding Tank: Use fresh water and one gallon of white vinegar solution… flush out twice. There are also
several holding tank treatment solutions available through local marine stores.
Head: refer to the head owner manual for proper cleaning solutions and maintenance.
Pumping a quart of fresh water type anti-freeze through the head system and hoses will prevent the seals
and equipment from cracking. The following hoses are connected to the tank.

Waste Discharge Hose from the head

Pump-out Hose leading to the deck fitting

Vent Hose to vent the tank overboard.
The holding tank must be pumped out before winter storage to avoid potential damage and the system shall
be empty during storage at freezing temperatures.


Alter or modify the rated current amperage of overcurrent protective devices;

Install or replace electrical appliances or devices with components exceeding the rated current amperage of the
circuit;
