Manual Flush Head System
The marine head installed on your boat uses seawater to flush waste from the toilet. The seawater intake valve (sea-
cock) is located under the removable entry step in the cabin.
Operating the manual flush marine head:
8.
Open the head’s seawater intake valve (seacock).
9. Before using the head, pump enough water into the bowl to wet the sides.
10. After use, pump until the bowl is thoroughly cleaned. Continue pumping a few more times to clean the lines. If
excess waste causes the water to rise in the bowl, stop pumping until the water recedes.
If you are unable to pump water into the bowl, the probable cause is debris in the pump diaphragm. To remedy this,
shut off the seawater intake valve (seacock) and 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).
To winterize the head, shut off the intake seacock and pump until the bowl is dry. Remove the drain plug in the base
and pump again to remove all of the water. Do not fill the bowl with anti-freeze. The intake seacock should be left
closed while the boat is underway or whenever the boat is left moored in the water.
