Plumbing Systems
General
The plumbing systems in your J/105 consist of fresh water, manual and electrical bilge pumps,
and a Raritan head (toilet). This section will describe their locations and how they operate.
Manual Fresh Water
•
Water Tank
-­‐ is made of polypropylene, is collapsible, and is simple to install. Simply
attach the hose from the foot pump to the tank.
•
Optional Water Tank -­‐ Part of the Systems Group package, this 20 gallon tank is made of
rotationally molded polyethylene. Entire capacity may not be usable depending upon
trim, loading, filling and draining points. Connected to it are the following hoses: a) fill
hose -­‐ located on the tank top and connecting to the deck water fill pipe; b) feed hose -­‐
located along the tank bottom connecting the water system to the manual pumps; c) vent
hose -­‐ internal and leads under the sheer line into the bow compartment.
Thru-­‐Hulls & Seacocks
All Seacock fittings are Forespar Marelon. For safety reasons, we recommend that you attach
with wire or wire-­‐tie an appropriate size tapered wooden plug in the vicinity of each of these
fittings in the event of a hose or valve failure. The fittings each have valve-­‐handles. To reduce
confusion, remember the long end of the handle indicates the direction of flow. Please refer to
the Seacock and Thru-­‐Hull diagram for a complete layout of locations and sizes.
Pump Systems
Pumps are easy to maintain and just as easily forgotten...they always happen to seize up when
you need them most. Consequently, take care to keep their screens clean and rubber
gaskets/bellows working correctly. There is one manual and one electric bilge pump system
installed standard in the J/105. Two pump intakes are located forward in the keel sump under
the main cabin centerline floorboard.
•
Manual Bilge Pump: The manual bilge pump is installed on the cockpit wall and operated
by opening the cover/handle and using an up and down manual pumping action. Bilge
water exits the boat from the manual pump through the transom.
•
Electric Bilge Pump: is wired direct with an in-­‐line fuse to the battery switch, so it is
always "on." This useful feature helps eliminate any accumulation of water in the bilge.
The switch is located near the electrical panel. The switch has three positions: ON, OFF,
and AUTO for self tending when you are not on the boat. Bilge water exits the boat from
the electric pump through a hose that loops up to a siphon break and then to the
overboard through-­‐hull fitting under the head sink.
•
Sink Drains empty directly overboard through a seacock fitting beneath the galley sink.
