4.1 General
Plumbing on a yacht (thru-hulls, valves, hoses and clamps), receives less attention regarding operation and maintenance than it deserves. Aside from bringing water in and letting water out, a yacht's plumbing has a third critical function, which is not analagous to domestic plumbing - namely to keep water out. As with most other components and systems, plumbing is also subject to the corrosive effects of saltwater and electrolytic action (see Section 1.12).
Lack of accessibility is partly the cause of neglect in many sailboats. Thru-hulls, valves and hoses are often hidden deep behind interior compartments and cabinet work. On the Ericson 34, this situation has been carefully considered and access to those fittings requiring regular and careful attention has been simplified by locating them in convenient areas. Opening a cabinet door or seat hatch provides easy exposure for anyone.
4.2 Thru-hulls - Specifications, Operation and Maintenance
The first step in familiarizing yourself with the Ericson 34 plumbing system is to locate all thru-hulls, know the function of each and its valve operation. Thru-hulls are located in three main areas:
Head compartment, beneath sink
- Sink drain with valve: 3/4" valve size | 1" black-wire rein
- Head intake with valve: 3/4" valve size | 3/4" black-wire rein
- Head discharge with valve (optional): 1-1/4" valve size | 1-1/2" black-wire rein
Galley, beneath sink
Larazette compartment
