Marine Head With Holding Tank

FLOODING HAZARD!
The marine head's seawater pickup seacock must be Closed before getting underway. This
seacock must remain Closed while the boat is underway or whenever the boat is left moored
and unattended.
Your boat may be equipped with a marine head
(toilet) and waste holding tank system. Be sure
to read the manufacturer's manual (included in
your boat's owner's packet)
• The marine head installed on your boat uses
seawater to flush waste from the toilet. The
seawater pickup valve (seacock) is located
under the entry steps in the cabin.
• Waste is routed directly from the head to the
holding tank.
• The holding tank is plumbed to a fitting on
the deck for dockside pump-out.
• You can determine the content level of the
holding tank by looking at the tank located
on the starboard side of the bilge. Empty the
holding tank at every opportunity.

Using The Marine Head

1. Open the marine head's seawater pickup
valve (seacock).
2. Before using the head, pump enough water
into the bowl to wet the sides.
3. After use, pump the head until the bowl
is clean.
• If excess waste causes the water to rise in the
bowl, stop pumping until the water recedes.
4. After the bowl is clean, pump a few more times to clean the lines.
If the seacock is Open, but you are unable to pump water into the bowl, the probable cause is debris in the pump
diaphragm. To remedy this:
1. Shut Off the seawater pickup valve (seacock).
2. Dismantle the pump. The pump is generally held together with six screws (the design is simple and the problem
will be obvious when the pump body is split Open).
3. Reassemble the pump.
4. Open the seacock.

Winterizing The Head

1. Shut Off the seawater pickup seacock.
2. Pump the head until the bowl is dry.
3. Remove the drain plug in the base and pump again to remove all of the water.
• Do not fill the bowl with anti-freeze.
