Transom Shower
Your yacht is equipped with a freshwater transom
shower, located inside the port transom stowage tub.
Fresh Water Washdown Faucet
The freshwater cockpit washdown faucet is located
on the port side of the aft cockpit.
Gray Water Drain System
•
Gray water (water from sinks and showers) above the waterline
is gravity drained overboard, while gray water below the water-
line is drained into a small holding tank that contains the sump
pump and float switch.
• The holding tank is located in the aft section of the utility room.
When the holding tank reaches a predetermined level, the tank’s
float switch automatically activates the sump pump to empty the
tank’s gray water overboard. After the tanks are drained, the
sump pumps are designed to automatically shut off.
• The shower sump pump and holding tank is located under the
companion way floor hatch.
• The sump pump should be periodically cleaned of debris and the
float switch tested for proper operation according to the instruc-
tions outlined in the bilge pump and float switch sections of this
supplement.
Raw Water System
Seacocks
Seacocks are valves which are typically used to manage the intake of raw water
through the hull below the water line (raw water intake seacocks). Seacocks
may also be used to discharge waste or water through the hull below the water
line (discharge seacocks).
Seacocks are controlled by a 90º lever and are used on your yacht in the following
raw water intake/discharge systems: Engines, generator system, (optional) air
conditioning system and standard marine head (toilet) system.
Raw Water Strainers
Raw water strainers are used in water pickup systems to filter incoming raw water. The typical layout is one strainer
for each of the following: Engine, generator and optional air conditioning system. Raw water strainers are located
near raw water intake valves (seacocks) and should be checked every time you use your yacht for leaks/or debris. If
debris is found, clean the strainer as follows:
