Plumbing Systems <br />

General <br />

The plumbing systems in your J/105 consist of fresh water, manual and electrical bilge pumps, <br />

and a Raritan head (toilet). This section will describe their locations and how they operate. <br />

<strong>Manual</strong> Fresh Water <br />

• Water Tank -­‐ is made of polypropylene, is collapsible, and is simple to install. Simply <br />

attach the hose from the foot pump to the tank. <br />

• Optional Water Tank -­‐ Part of the Systems Group package, this 20 gallon tank is made of <br />

rotationally molded polyethylene. Entire capacity may not be usable depending upon <br />

trim, loading, filling and draining points. Connected to it are the following hoses: a) fill <br />

hose -­‐ located on the tank top and connecting to the deck water fill pipe; b) feed hose -­‐ <br />

located along the tank bottom connecting the water system to the manual pumps; c) vent <br />

hose -­‐ internal and leads under the sheer line into the bow compartment. <br />

Thru-­‐Hulls & Seacocks <br />

All Seacock fittings are Forespar Marelon. For safety reasons, we recommend that you attach <br />

with wire or wire-­‐tie an appropriate size tapered wooden plug in the vicinity of each of these <br />

fittings in the event of a hose or valve failure. The fittings each have valve-­‐handles. To reduce <br />

confusion, remember the long end of the handle indicates the direction of flow. Please refer to <br />

the Seacock and Thru-­‐Hull diagram for a complete layout of locations and sizes. <br />

Pump Systems <br />

Pumps are easy to maintain and just as easily forgotten...they always happen to seize up when <br />

you need them most. Consequently, take care to keep their screens clean and rubber <br />

gaskets/bellows working correctly. There is one manual and one electric bilge pump system <br />

installed standard in the J/105. Two pump intakes are located forward in the keel sump under <br />

the main cabin centerline floorboard. <br />

• <strong>Manual</strong> Bilge Pump: The manual bilge pump is installed on the cockpit wall and operated <br />

by opening the cover/handle and using an up and down manual pumping action. Bilge <br />

water exits the boat from the manual pump through the transom. <br />

• Electric Bilge Pump: is wired direct with an in-­‐line fuse to the battery switch, so it is <br />

always "on." This useful feature helps eliminate any accumulation of water in the bilge. <br />

The switch is located near the electrical panel. The switch has three positions: ON, OFF, <br />

and AUTO for self tending when you are not on the boat. Bilge water exits the boat from <br />

the electric pump through a hose that loops up to a siphon break and then to the <br />

overboard through-­‐hull fitting under the head sink. <br />

• Sink Drains empty directly overboard through a seacock fitting beneath the galley sink.
